Embracing uncertainty<br />

It was Winston Churchill who said,<br />

“Without a measureless and perpetual<br />

uncertainty, the drama of human<br />

life would be destroyed.” Well, life is<br />

certainly interesting at the moment<br />

but, like most business owners, I’d<br />

probably settle for a little less drama<br />

and a little more certainty.<br />

If the recent drama involving the<br />

two women from the UK who drove<br />

to Wellington to see a dying relative,<br />

resulting in a litany of isolation<br />

breaches, teaches us anything, it’s<br />

that nothing is certain. But, as all<br />

the experts tell us, it’s also from<br />

uncertainty, especially in tough times,<br />

that we learn to adapt, to change,<br />

leading to better products and ways<br />

of doing business.<br />

One change we’ve introduced is our newly redesigned, now A4<br />

magazine. We hadn’t planned the change; it was made in response to NZ<br />

Post’s decision to alter its processes as it attempts to improve efficiencies<br />

in the pandemic’s wake. We hope you like it. We think it’s a good change<br />

that has other benefits too, for us, for our advertisers and for you, we<br />

hope, as we will now fit better into your bags and your hand.<br />

This is also the last month we’ll be providing the magazine free online as<br />

soon as it’s published, returning to our pre-pandemic subscription model,<br />

which we paused for three months to help us all get through. Without<br />

planning, David Slack discusses the plight of the media in this month’s<br />

The only certainty is that<br />

nothing is certain,<br />

Pliny the elder<br />

Experiencing the emotional ups and downs of uncertainty isn’t always a bad thing<br />

Chalkeyes presents (p38) and puts into<br />

words something we espouse, “…<br />

publications that speak to our interests<br />

and values, that cares about our<br />

community of interest, about you, are<br />

something to prize.” Thus, this month’s<br />

magazine, together with all the news<br />

and clinical learnings, continues to<br />

provide what we hope is a plethora of<br />

useful advice to support you and your<br />

businesses during these uncertain times.<br />

As David Pearson, our long-term<br />

financial commentator, writes in<br />

his Focus on Business column (p32)<br />

getting through successfully isn’t<br />

about making big leaps, “…it’s about<br />

incremental change: take a small step,<br />

reflect, learn, adjust and take another<br />

small step.”<br />

The last several weeks have been a bit of a roller coaster ride<br />

emotionally, and probably continues to be for many of us, but as Siu-<br />

Yin Shing says in this month’s Style Eyes (p34), developing a resilient,<br />

successful business is based on creating a positive, lasting impression<br />

among your target audience. Hopefully,<br />

that’s something we’re achieving. We<br />

welcome your feedback.<br />

All the best,<br />

Sharing her work into the limitations of the B4 School<br />

Check when it comes to our kids’ visual acuity (p10),<br />

Auckland University researcher Rebecca Findlay<br />

says she’s always been interested in science, and<br />

optometry was a great way to combine science with<br />

working with people. “I love that in my job and in my<br />

research, I have the opportunity to make a difference in<br />

kids’ lives in a very meaningful way by improving not only their vision but<br />

their potential to learn in the school environment.” When not working,<br />

she says she particularly enjoys spending time with her family, travelling<br />

(pandemics allowing) and getting creative with craft activities.<br />

Tracey Ellin<br />

Behind the scenes, beavering away to make your<br />

NZ Optics magazine look as beautiful as it does, is<br />

our own Tracey Ellin, who this month gets a special<br />

‘contributor’ mention for redesigning our magazine,<br />

at short notice, to a standard A4 format. This is the<br />

second time Tracey has redesigned the magazine<br />

as she was also responsible for changing our old, A3<br />

newspaper format into our much lauded (thank you!)<br />

more reader-friendly, magazine-style publication in mid-2018.<br />

Tracey is a former nurse who retrained as a graphic designer after her<br />

children started school. From the get-go she loved the process of making<br />

a magazine and being part of a small team, she says. Having worked for<br />

several interior and lifestyle magazines, she’s also expanded her design<br />

knowhow by completing Unitec’s interior design programme and working<br />

part-time for Auckland design store, The Ivy House. In her spare time,<br />

she’s kept busy upskilling her photography and video knowledge, making<br />

things, walking the dog, spending time with family and taking the odd<br />

adult ballet class. For rest, she says she loves a good film or book and<br />

reading magazines, preferably printed ones!<br />

NEWS<br />

Celebrating excellence despite Covid<br />

By Lesley Springall<br />

THE MUCH-ANTICIPATED<br />

Excellence in Ophthalmology<br />

and Vision Research Prize<br />

Evening may have been<br />

knocked back by the Covid-19<br />

pandemic, but the <strong>2020</strong><br />

awardees are still being<br />

recognised and will be invited<br />

to receive their awards at a<br />

special, celebratory event later<br />

this year.<br />

Professor Charles<br />

McGhee, chair and head<br />

of ophthalmology at the<br />

University of Auckland, said<br />

it’s been two years of upset for<br />

the awards unfortunately, with<br />

last year’s 20-year anniversary<br />

celebrations cancelled<br />

following the Christchurch terror attack. The<br />

awards still went ahead, but were a sombre<br />

event given the effect of the attacks on many at<br />

the university.<br />

But now a new event is being planned,<br />

“hopefully” in September, said Prof McGhee,<br />

to truly celebrate the excellence awards 23rd<br />

anniversary and the growth and success of the<br />

expanded department as it notches up its 21st.<br />

It will also celebrate all past award winners,<br />

including this year’s, he said. “We never<br />

envisaged the Department of Ophthalmology<br />

would grow so rapidly, nor the number of truly<br />

outstanding undergraduate and postgraduate<br />

research students that would pass through<br />

our hands, but this now numbers more than<br />

100, many of whom are now in national and<br />

international leadership roles.”<br />

Prof McGhee congratulated this year’s award<br />

winners who have all been notified. They were<br />

all very worthy recipients whose work and<br />

commitment to ophthalmology continues<br />

the strong legacy of the awards and the<br />

department, he said. “Year-on-year, the standard<br />

of our students increases exponentially and<br />

this year, many exhibit outstanding academic<br />

credentials alongside impressive sporting, music<br />

and other achievements. Indeed, it makes me<br />

glad I am not competing for a career as a young<br />

doctor in <strong>2020</strong> as I might struggle in such an<br />

exemplary epoch!”<br />

The Calvin Ring Prize – Shin Jee Tang<br />

The Calvin Ring Prize is awarded to the best<br />

all-round undergraduate medical student in<br />

clinical ophthalmology.<br />

This year’s award winner, Shin Jee Tang, is<br />

a final-year trainee intern at Waikato Hospital.<br />

She hopes to pursue a career in ophthalmology<br />

as it offers a good mix of both medicine and<br />

surgery, she said. “Winning the Calvin Ring Prize<br />

meant a lot to me as my effort, enthusiasm and<br />

passion in ophthalmology were recognised and<br />

Excellence in Ophthalmology <strong>2020</strong> awardees, Shin Jee Tang, Sunny Sixiao Li and Keli Matheos<br />

acknowledged. It further fortifies my love for<br />

this specialty and hopefully serves as a good<br />

steppingstone when I apply to join the training<br />

programme.”<br />

The William MacKenzie Medal –<br />

Sunny Sixiao Li<br />

Recognising the significant contribution made<br />

by a medical student or trainee intern towards<br />

a published research project, the William<br />

MacKenzie Medal was awarded to second-year,<br />

Auckland-based house officer Sunny Sixiao Li.<br />

Li’s research focused on corneal wound<br />

healing following cataract surgery, which<br />

resulted in a number of published studies.<br />

These included the validation of questionnaires<br />

for prioritisation of elective cataract surgery<br />

in New Zealand (The New Zealand Medical<br />

Journal); corneal biomechanical changes<br />

following cataract surgery (Clinical and<br />

Experimental Ophthalmology); and prediction<br />

of pseudophakic refractive error (Journal of<br />

Cataract and Refractive Surgery).<br />

Li said she was both honoured and humbled<br />

to join the illustrious list of past recipients of<br />

the Medal. “This would not have been possible<br />

without my supervisors, Dr James McKelvie<br />

and Dr Stuti Misra, who have encouraged and<br />

supported me endlessly with their wealth of<br />

experience and wisdom.” Also thanking Prof<br />

McGhee and the ophthalmology department,<br />

Li said she hopes to continue her work in eye<br />

research for some time to come.<br />

The Arthur Thomas Paterson<br />

Scholarship – Dr Kaliopy Matheos<br />

The <strong>2020</strong> Arthur Thomas Paterson Scholarship,<br />

designed to assist with overseas postgraduate<br />

training, was awarded to Dr Kaliopy Matheos.<br />

Dr Matheos began her fellowship training<br />

with the glaucoma team at the Greenlane<br />

Clinical Centre in Auckland before using the<br />

award to help her gain further experience as<br />

the glaucoma and anterior segment fellow<br />

at the University of Toronto in Canada. Her<br />

focus there was primarily on the management<br />

of complex glaucoma cases but included an<br />

interesting foray into the surgical management<br />

of ectopia lentis, she said.<br />

Winning the award was a huge honour, said<br />

Dr Matheos. “The scholarship meant I have<br />

been able to achieve many of the goals I set out<br />

to achieve when embarking on my fellowship<br />

training.”<br />

Eyes reveal true age<br />

BOSTON UNIVERSITY<br />

MEDICAL researchers<br />

have discovered a<br />

specialised eye scanner<br />

that accurately measures<br />

spectroscopic signals<br />

from proteins in the lens<br />

can also detect and track A/Prof Lee Goldstein<br />

biological aging.<br />

Chronological age does not adequately<br />

measure individual variation in the rate of<br />

biological aging, said study lead, Associate<br />

Professor Lee Goldstein. “The absence of<br />

clinical tools and metrics to quantitatively<br />

evaluate how each person is aging at<br />

the molecular level represents a major<br />

impediment to understanding aging and<br />

maximising health throughout life. The lens<br />

contains proteins that accumulate agingrelated<br />

changes throughout life. Our eye<br />

scanner can decode this record.”<br />

The study was published in the Journal of<br />

Gerontology: Biological Sciences.<br />

oDocs’ inaugural award winner<br />

INNOVATIVE EYE CARE technology enterprise oDocs Eye Care has<br />

awarded it’s first oDocs Project Grant Award to fifth year Otago medical<br />

student Aqeeda Singh.<br />

The new $5,000 award is designed to promote sight saving initiatives<br />

and innovative research projects by medical students and residents, fellows<br />

and researchers in the field of ophthalmology, said oDocs founder and<br />

ophthalmology registrar Dr Sheng Chiong Hong.<br />

Singh was chosen as the inaugural recipient of the new award given her<br />

continuous achievement over the past year and the number of high-quality<br />

research papers she’s published, he said. “Her tenacity and hard work in<br />

ophthalmic science and research made her an outstanding candidate.”<br />

Singh is using the grant to continue her work into creating guidelines<br />

for acute ophthalmic conditions that present in primary care, creating a<br />

protocol for non-eye specialists as part of a bigger teleophthalmology<br />

project with oDocs’ sister company MedicMind. “This will help simplify<br />

the management for clinicians hopefully,” she said. “The project is also<br />

giving me a chance to satiate my eagerness to learn more about eyes!”<br />

Singh said she’s keen to continue her journey in ophthalmology when<br />

she graduates. “As a child, I used to say the eyes were my favourite body<br />

part and it hasn’t really changed… However, almost every consultant has<br />

advised us to remain flexible and keep our minds open!”<br />

Thanking Dr Hong and her senior lecturer Dr Kelechi Ogbuehi, she said<br />

she owes a great deal to their support and “encouraging nature” to have<br />

got to where she is today. “I couldn’t have asked for better supervisors.”<br />

The oDocs Project Grant Award will initially be awarded annually, but<br />

the plan is to increase this, said Dr Hong. Award winners are selected<br />

by Drs Hong, Ogbuehi and, oDocs co-founder, Ben O’Keeffe after being<br />

A RECENT AUSTRALIAN survey<br />

has found many parents are<br />

shocked to learn their children<br />

have vision problems and struggle<br />

with a range of issues and<br />

emotions at the time of diagnosis<br />

and during treatment.<br />

The Little Aussie Eyes Report<br />

by Kids Eye Gear surveyed 450<br />

Australian parents of children with<br />

vision issues to provide insight<br />

into their concerns, said Nicola<br />

Rivett, Kids Eye Gear founder and<br />

mother of a son who required<br />

patching due to congenital<br />

cataract and subsequent surgery.<br />

“Noticing that your child has a<br />

vision problem is not always easy.<br />

Kids don’t know that what they see<br />

isn’t ‘normal’. They learn to adapt to<br />

what sight they have and parents<br />

can be completely unaware there is<br />

an underlying issue.”<br />

Consequently, many parents<br />

are shocked to find out their child<br />

has a vision problem, she said,<br />

describing feelings of guilt, being<br />

overwhelmed and recalling the<br />

diagnosis as a very emotional<br />

experience. “I was actually very sad<br />

and emotional,” one respondent<br />

to the survey said while another<br />

said they were “shocked, confused,<br />

worried and overwhelmed”.<br />

The majority of parents<br />

surveyed had children who wear<br />

prescription glasses (81%), with<br />

70% diagnosed between the ages<br />

of two and five. The three main<br />

challenges parents identified with<br />

kids and glasses were: keeping<br />

glasses clean (62%); finding<br />

frames that fit (43%); and finding<br />

affordable glasses (41%).<br />

Of those surveyed, 82% had<br />

experience of patching, with one in<br />

four of their children<br />

prescribed at age<br />

four and just over<br />

half (53%) prescribed<br />

between two and<br />

five. The main reason<br />

for patching was<br />

amblyopia (60%).<br />

By far the<br />

Nicola Rivett<br />

biggest challenge<br />

with patching, identified by<br />

parents, was getting the child<br />

to actually wear the patch in the<br />

first instance (65%), followed by<br />

finding affordable patches (43%)<br />

and patches that didn’t irritate<br />

the child’s skin (30%), and fitting<br />

in the required patch time in<br />

their daily lives (30%). As many<br />

as 58% of parents surveyed said<br />

it was stressful having to patch<br />

their child. Though many said<br />

establishing a routine helped, with<br />

51% preferring to patch in the<br />

morning while providing close-up<br />

activities for the child, such as<br />

iPad/tablet, television, playing<br />

with toys or doing crafts.<br />

Commenting on the report,<br />

Rivett said she has “huge” respect<br />

for eye health professionals and<br />

hoped the findings<br />

will encourage<br />

them to continue<br />

advocating for early<br />

vision screening and<br />

providing exceptional<br />

care.<br />

“As the study<br />

showed, many<br />

parents experience<br />

feelings of surprise, shock and<br />

guilt when their young one is<br />

diagnosed with a vision problem.<br />

If eye care professionals can be<br />

empathetic to these feelings and<br />

equip parents with resources to<br />

understand their child’s condition,<br />

or at least point them in the<br />

right direction for additional<br />

information, this will help alleviate<br />

any initial negative feelings or<br />

fear about the diagnosis. I believe<br />

this would create increased<br />

positive outcomes for the child’s<br />

vision and further strengthen the<br />

practitioner/patient relationship.”<br />

RESEARCH<br />

Worrying results from WTS study<br />

By Rebecca Findlay<br />

UNCORRECTED REFRACTIVE ERRORS<br />

account for up to 96% of visual impairment<br />

in school-aged children and are<br />

associated with amblyopia and strabismus<br />

development, and reduced performance<br />

in early literacy tests, reading ability<br />

and academic achievement. Amblyopia<br />

treatment is most effective before seven<br />

years of age, thus, it’s important to identify<br />

children with amblyopia risk factors at a<br />

young age.<br />

Preschool children in New Zealand<br />

receive a universal, free, well-child check,<br />

the B4 School Check (B4SC), at four-yearsold<br />

to identify behavioural, developmental<br />

and other health concerns which could<br />

negatively impact their ability to learn. The<br />

B4SC has excellent coverage, with 96.7%<br />

of eligible children and 94.5% of children<br />

living in high deprivation communities in<br />

the Auckland region, completing the check<br />

in 2017. As part of the B4SC, children’s<br />

visual acuity (VA) is screened using the Parr<br />

vision chart, specifically to identify children<br />

with amblyopia. Distance VA measurement<br />

is more effective for myopia detection than<br />

hyperopia and astigmatism. There are currently<br />

no contemporary refractive error data for New<br />

Zealand children and it’s unknown whether<br />

ethnic differences exist, particularly for Māori<br />

and Pacific children.<br />

The study<br />

The Welcome to School (WTS) study was<br />

a multidisciplinary, collaborative study of<br />

children from schools in the Manaiakalani<br />

Community of Learning in Tāmaki: the<br />

Auckland suburbs of Glen Innes, Point England<br />

and Panmure.<br />

The aims of the study were to determine<br />

the prevalence of refractive error and visual<br />

impairment in a cohort of six to seven-year-old<br />

children and evaluate the efficacy of the B4SC<br />

programme in the multicultural community of<br />

Tāmaki, where the majority of children are of<br />

Māori or Pacific ethnicities.<br />

Coffee’s surgery impact<br />

Children were recruited on school entry<br />

and received a comprehensive health,<br />

developmental and social assessment. These<br />

same children and whānau were contacted by<br />

the WTS research nurse approximately one year<br />

later at six to seven years of age. 114 children<br />

received a comprehensive cycloplegic vision<br />

examination in their schools.<br />

Results<br />

Almost one third (31.6%) of participants had<br />

significant refractive error, of which 80.6% was<br />

astigmatism. Myopia prevalence was low (3.5%)<br />

and seven participants (6.1%) had amblyopia<br />

risk factors. The B4SC vision screening was<br />

effective in detecting amblyopia, with no<br />

child with amblyopia risk factors passing the<br />

screening. Though a significant number of<br />

children (11.4%) did not receive a B4SC vision<br />

screening and a similar number (10.5%) were<br />

identified for B4SC rescreening which had not<br />

been completed. Both included children with<br />

amblyopia risk factors.<br />

The B4SC was ineffective, however, at<br />

study assessed the effects of caffeine alone, a β-blocker (propranolol)<br />

alone or a β-blocker and caffeine combination on the surgical<br />

performance of 15 VR surgeons with less than two years surgical<br />

experience.<br />

Propranolol alone was associated with improved surgical<br />

performance compared with caffeine alone and the combination of caffeine and propranolol,<br />

suggesting caffeine negatively affects surgical performance. “These results may be helpful for<br />

novice vitreoretinal surgeons to improve microsurgical performance,” said the authors.<br />

detecting significant refractive error with<br />

more than half the children with significant<br />

refractive error passing. Only 13.9% of<br />

children with significant refractive error<br />

and 57.1% with amblyopia risk factors were<br />

wearing glasses at the time of assessment.<br />

Nearly 60% of children with significant<br />

refractive error passed the screening and<br />

none were wearing glasses, suggesting<br />

children who passed were unlikely to have<br />

had a comprehensive eye examination<br />

which would have detected mild to<br />

moderate uncorrected refractive error.<br />

Consequently, many children in this cohort<br />

started school with uncorrected refractive<br />

errors potentially impacting their academic<br />

performance.<br />

Recommendations<br />

There is currently a mismatch between the<br />

aims of the vision screening programme,<br />

which is targeted at detecting amblyopia,<br />

and the overall B4SC which aims to detect<br />

and intervene on issues which could adversely<br />

impact educational outcomes, particularly for<br />

socioeconomically disadvantaged Māori and<br />

Pacific children. This mismatch, in combination<br />

with the differential reach of the B4SC, is likely<br />

to be increasing inequities.<br />

This study suggests urgent attention is<br />

required to review the B4SC vision screening<br />

protocol to ensure it is appropriate and<br />

equitable, so all children receive high quality<br />

vision screening and eye care to improve<br />

their health, educational and social outcomes.<br />

Alternative screening strategies may be more<br />

appropriate to detect refractive error. A review<br />

of the Well Child Tamariki Ora programme<br />

is currently underway and provides an<br />

opportunity to re-examine the rationale for<br />

preschool vision screening and follow-up<br />

protocol. While eligible children can receive the<br />

Enable subsidy for glasses, the process can be<br />

difficult for families to navigate. Cost should<br />

not be a barrier. Eye care services should be<br />

available for all children. Culturally appropriate<br />

coordination is necessary to ensure children<br />

who are referred or identified for rescreening<br />

receive follow up and are assisted in accessing<br />

services.<br />

The post-Covid<br />

shopping street<br />

By Jai Breitnauer<br />

NEW ZEALAND HAS fared well globally in<br />

the fight against Covid-19, but it has not been<br />

without cost. It is only now the smoke is clearing<br />

enough to see how the pandemic has affected<br />

our main shopping thoroughfares and what<br />

impact that may have on optometry practices.<br />

Thankfully, the big picture is looking much<br />

better than expected. With a fiscal stimulus<br />

package amounting to $62.1bn mixed with<br />

quantitative easing and a low interest rate,<br />

we’ve seen commentators roll back on their<br />

dire predictions. Indeed, figures from early<br />

June show retail spending is down just 2% on<br />

last year, with The Bank of New Zealand now<br />

predicting GDP will return to pre-Covid levels<br />

by mid-2022, rather than the fourth quarter<br />

of 2023 as previously suggested. However,<br />

a recent Euromonitor International report<br />

suggests globally, real economic growth will be<br />

at its lowest this year since 1961, so there’s no<br />

room to be complacent.<br />

Complacency is one path Andrew Judd<br />

could not afford to take. The owner of New<br />

Plymouth-based Judd Opticians said they used<br />

their time in level 4 lockdown to evaluate their<br />

business model.<br />

“The week prior to lockdown we were<br />

already starting to be impacted by Covid-19,<br />

mostly in a reduction of forward appointments<br />

and foot traffic,” Judd said. “Obviously, going<br />

The need for<br />

eyewear hasn’t gone<br />

away. Use social<br />

media to promote<br />

your business in a<br />

gentle way<br />

into level 4 the impact was immediate. We<br />

used the time to evaluate and plan what postlockdown<br />

could look like. Fundamentally what<br />

we do remains, but it’s how we now do it.”<br />

Increased online power<br />

Judd identified that for his business, one<br />

key area of deficit was online, and with the<br />

Euromonitor report suggesting e-commerce<br />

retailers are one of the four types of retail<br />

business that will fare best through this crisis,<br />

that doesn’t seem like a bad place to start.<br />

“We researched all available business<br />

support and secured regional development<br />

funding towards upgrading our online activity.<br />

We also reached out to surrounding businesses<br />

to jointly promote on social media,” said Judd,<br />

adding the joint online promotion had an<br />

immediate positive impact on his business.<br />

Daniel Feldman, a founding member of<br />

The Visionaries Group in the US and owner<br />

of the Optical Journal podcast, said in a recent<br />

instalment of his show that if businesses aren’t<br />

advertising, he doesn’t know how they are<br />

staying afloat.<br />

“You Tube have stopped optimising their<br />

videos to save on bandwidth, a recognition<br />

of the amount of time people are spending<br />

online,” he said. “The reach I am getting in<br />

Google ads is three to four times what I was<br />

getting in February. Everyone has stopped<br />

FEATURE<br />

advertising, so I am not competing for eyeballs<br />

as I was before. The need for eyewear hasn’t<br />

gone away. Use social media to promote your<br />

business in a gentle way.”<br />

New Zealand retail consultant Chris<br />

Wilkinson agreed for reaching consumers<br />

online sales and advertising activity is of<br />

greater importance right now.<br />

“There is likely to be less footfall as we<br />

come out of this as consumer behaviour<br />

changes with more ‘purposeful’ journeys, less<br />

browsing and, consequentially, fewer impulse<br />

sales opportunities. More transactions will<br />

likely start online as people browse ranges<br />

and availability but still, the majority will end<br />

in store. This means that businesses need to<br />

redouble efforts around their online profile<br />

and user experience.”<br />

Doubling efforts in-store<br />

User experience in-store is another essential<br />

area optometry businesses need to be working<br />

on as things ramp up, continued Wilkinson.<br />

“Trust, welcome and recognition will be<br />

even more vital as we come out of the Covid<br />

environment. There is already trepidation<br />

from consumers about medical environments,<br />

so any situation which relies on one-on-one<br />

interactions needs extra reassurance and<br />

confidence.”<br />

Lisa Donaldson of Retail X consultancy<br />

said business owners should plan out their<br />

physical stores in line with social distancing<br />

measures, but with user experience at the<br />

forefront of their<br />

mind.*<br />

“Walk your<br />

store as a shopper<br />

would to assess<br />

how your current<br />

environment meets<br />

the recommended<br />

health<br />

requirements.<br />

What can you do<br />

to improve the flow<br />

of shoppers in your<br />

space?”<br />

Katrina Hammon: look at<br />

local marketing<br />

Donaldson<br />

recommended<br />

freeing up space<br />

where you can,<br />

especially in the ‘landing zone’ at the front<br />

of your practice, by removing displays. “You<br />

might have to adapt to trade with less product<br />

on the floor. To support this, you may need<br />

to reorganise storage space, replenish your<br />

product displays more frequently or present<br />

your product in new ways.<br />

“Engage with shoppers through<br />

How will shoppers’ habits change post-Covid?<br />

meaningful, well-thought-out displays and<br />

storytelling – not just loads of product on a<br />

stand.”<br />

Solicitor Katrina Hammon, a franchise<br />

specialist and partner at Wynn Williams in<br />

Christchurch, said she believes that franchise<br />

opportunities may become more desirable in<br />

this new post-Covid climate, offering greater<br />

security to franchise holders.<br />

“The larger, corporate-owned or franchised<br />

networks have been ramping up their<br />

digital marketing and pushing online sales.<br />

Larger competitors will also be leveraging<br />

relationships and special offers to gain more<br />

market share and exploit additional channels<br />

to market to these potential new patients.”<br />

Hammon said it is a big decision, but<br />

if you are now considering a franchise<br />

opportunity, make sure you understand the<br />

fees and exit payments, and complete your<br />

own due diligence. Also look at what help the<br />

franchisor can offer with rent on premises,<br />

especially if you can’t trade.<br />

Consider local marketing initiatives<br />

For those flying solo, she also has good advice.<br />

“[Smaller businesses should] look at local<br />

marketing opportunities… local papers or<br />

radio advertising… building partnerships<br />

and relationships with aged-care facilities,<br />

industry associations, business groups and<br />

even larger businesses may be an option.<br />

Given the diverse population in New Zealand,<br />

it is also sound advice to consider if you could<br />

better market to different ethnic groups. For<br />

example, have advertisements translated for<br />

The Indian News, Chinese Herald or Home<br />

Voice Chinese Newspaper. Your employees<br />

should take the time to understand crosscultural<br />

communication and focus on the<br />

experience being welcoming for all.”<br />

Andrew Judd said<br />

this post-Covid retail<br />

landscape actually<br />

presents some<br />

good opportunities<br />

for independent<br />

optometrists given<br />

their business model<br />

is based on longstanding<br />

patients and<br />

building trust.<br />

“These changing<br />

times offer an<br />

exciting opportunity Andrew Judd: consider<br />

for private practice joint, online promotions<br />

to re-establish the<br />

narrative of our<br />

profession. As a dispensing optician who<br />

qualified with the skills of edging and fitting,<br />

frame repairs and adjustments, I was called<br />

upon over level 4 and level 3 to use those skills<br />

to assist frontline workers. I mention this to<br />

remind our profession that we have many<br />

aspects to patient care. It is the practice that<br />

builds long-term trust and service that will<br />

remain and grow.”<br />

MyHealth1st launches managed<br />

advertising services<br />

By 1st Group<br />

THE COVID-19 PANDEMIC has, to put it mildly,<br />

made things hard for businesses across New<br />

Zealand. Even with lockdown restrictions being<br />

eased and the world slowly returning to the<br />

new normal, consumer confidence is low, so<br />

making sure patients return to your practice<br />

is vital, not only for the financial wellbeing of<br />

your practice but for the eye health of your<br />

patients as well.<br />

Since 1stGroup launched MyHealth1st in<br />

2012, it has been dedicated to one mission –<br />

making it simple for patients to connect with<br />

practices to get the healthcare they need in<br />

a timely and effective manner. This mission<br />

statement drives all our efforts, from how<br />

we consistently improve our online booking<br />

process to the launch and support of new<br />

products and services. As such, expanding<br />

into helping practices succeed through digital<br />

advertising was a necessary step to ensure our<br />

goal of connecting patients with the eye health<br />

services they need.<br />

At MyHealth1st, we understand the<br />

challenges that come with running an<br />

independent optometry practice because we<br />

work with thousands of practices just like yours,<br />

right around New Zealand and Australia. It’s<br />

because of this understanding of the needs of<br />

independent practices that we have developed<br />

our managed advertising service.<br />

So what exactly are we offering? We will<br />

provide managed Google and social media<br />

advertising campaigns for all practices, with<br />

packages and offers being individually tailored<br />

to meet the needs of single practices and<br />

chains alike. Google advertising, an active<br />

social media presence and well targeted social<br />

Covid-19 breathalyser<br />

media advertising on Facebook and Instagram<br />

are of vital importance when it comes to<br />

increasing the visibility of any practice.<br />

An effectively managed Google advertising<br />

plan can help you climb to the top of search<br />

engine rankings, so you can reach more<br />

patients at every stage of the booking funnel,<br />

from patients researching symptoms to<br />

making the decision, to actively booking<br />

an appointment for an eye test, glasses or<br />

contact lens fitting or other consult. Our<br />

team has extensive experience planning,<br />

OHIO STATE UNIVERSITY researchers are testing a new breathalyser that could act as a cheap,<br />

quick and more patient-friendly test for Covid-19 compared with the current deep nasal swab.<br />

The new project builds on primary investigator Professor Perena Gouma’s invention of a<br />

hand-held breath monitor for the early detection of flu. The sensor detects nitric oxide and<br />

volatile organic compounds from a person’s breath, which can indicate the onset of an infectious<br />

disease. Testing for this has now been expanded to two other metabolites that can reveal if a<br />

person is infected with Covid-19, even if they’re<br />

asymptomatic, she said. “Exhaling once in the<br />

breathalyser may help with earlier detection of<br />

the onset of the disease, as well as monitoring<br />

the severity of infection… allowing more timely<br />

therapeutic intervention.”<br />

If proved accurate, the breathalyser could become<br />

a key diagnosis platform for a range of metabolic<br />

diseases such as cancer, Alzheimer’s or diabetes,<br />

by simply choosing the appropriate biomarker to<br />

sample, said Prof Gouma adding it will also allow for<br />

mass screening at airports or other gatherings.<br />

Prof Perena Gouma with the prototype<br />

implementing and managing successful and<br />

cost-effective Google AdWords campaigns. We<br />

want to drive new patients to optical practices<br />

and a managed Google advertising service<br />

allows practices to monitor and measure the<br />

advertising spend and return on investment for<br />

each campaign.<br />

A social media presence is vital, but there’s<br />

no point in putting money or effort into ads<br />

if they’re not being seen by the right people<br />

or the messaging is wrong. Managed social<br />

media advertising can plan and roll out<br />

campaigns across Facebook, Instagram and<br />

LinkedIn and help practices reach the right<br />

people in the right areas to help you achieve<br />

your goals.<br />

With a tailored Google and social media<br />

marketing campaign, you will be able to<br />

reach more patients in your area as well as<br />

re-engage with existing patients that may have<br />

been putting off visiting your practice due to<br />

Covid-19 fears. With our tailored, managed<br />

advertising services your messaging will be<br />

unique to your practice, speaking directly<br />

to your market, speeding your recovery<br />

after this time of economic uncertainty<br />

and differentiating your practice from your<br />

competitors.<br />

Vision therapy inspired by bats<br />

EUROPEAN SCIENTISTS HAVE developed a new therapeutic approach<br />

based on gene therapy, that could provide a new form of sight to<br />

patients suffering from degenerative eye diseases such as macular<br />

degeneration (MD) and retinitis pigmentosa (RP).<br />

MD and RP are caused by the degeneration of photoreceptors.<br />

Researchers from the Institute of Molecular and Clinical Ophthalmology<br />

Basel and the German Leibniz Institute for Primate Research (DPZ)<br />

successfully re-activated degenerated photoreceptors allowing animal<br />

models to see infrared heat signatures without negatively affecting<br />

remaining vision.<br />

The team were inspired by bats and snakes which use infrared heat<br />

signatures alongside typical vision to hunt prey. This enables bats and<br />

snakes to superimpose thermal and visual images in the brain and thus<br />

react to their environment with greater precision. To replicate this, the team<br />

developed a three-component system. The first element was engineered<br />

DNA, ensuring gene coding for the heat-sensitive channel is only expressed<br />

in photoreceptors; the<br />

second, a gold nanorod<br />

that efficiently absorbs<br />

near-infrared light; and<br />

the third, an antibody<br />

to bind the first two<br />

together.<br />

Trialling the system<br />

on mice with retinal<br />

degeneration, the<br />

team confirmed nearinfrared<br />

light effectively excited the photoreceptors and the signal was<br />

transmitted to the higher visual centres in the brain. Encouraged by this,<br />

co-author, Assistant Professor Arnold Szabo from Semmelweis University<br />

in Hungary, tested the model on cultured human retinas, successfully<br />

reactivating their visual circuitry. The study was published in Science.<br />

THE FINAL REPORT on the<br />

government’s long-awaited Health<br />

and Disability System Review<br />

confirmed New Zealand’s health<br />

services and workforce are under<br />

considerable stress and the health<br />

system is complex and fragmented.<br />

Though our system is better than<br />

many, the review sets out a path<br />

towards a better, more sustainable<br />

health system with clear lines of<br />

accountability, said health minister<br />

Dr David Clark. “One that is more<br />

responsive to the needs of local<br />

communities.”<br />

Chaired by health economist<br />

l Creating a new crown entity,<br />

provisionally called Health NZ,<br />

Primary retinal telangiectasia<br />

By Dr Shanu Subbiah<br />

PRIMARY OR CONGENITAL<br />

retinal telangiectasia, more<br />

commonly called Coats’ disease<br />

or Coats’ syndrome, is a nonhereditary,<br />

developmental, retinal<br />

vascular disorder characterised<br />

by dilatation and exudation of<br />

the retinal vasculature, and an<br />

important cause of leucocoria in<br />

children.<br />

Case report<br />

A 13-year-old boy attended the<br />

emergency eye clinic with a oneday<br />

history of sudden onset loss<br />

of superior field of vision affecting<br />

his right eye. He had been<br />

trampolining the previous day.<br />

There was no history of trauma,<br />

photopsia or floaters. He had no<br />

past ocular history and was in<br />

good general health. He was not<br />

premature and had achieved all<br />

developmental milestones.<br />

On examination, visual acuity<br />

was 6/24+1 right and 6/4 left.<br />

He had a relative afferent pupil<br />

defect in his right eye. He was<br />

orthotropic on cover testing.<br />

Anterior segment examination<br />

was normal. Dilated fundal<br />

examination of his right eye<br />

revealed marked intraretinal<br />

exudation with an inferior<br />

non-rhegmatogenous retinal<br />

detachment and multiple large<br />

telangiectatic vessels with light<br />

bulb-shaped aneurysms (Fig<br />

1 and 2). The left retina was<br />

normal. Indirect indentation<br />

ophthalmoscopy of his right<br />

retina did not reveal any<br />

peripheral retinal tears. Ocular<br />

ultrasound revealed no posterior<br />

segment mass. A provisional<br />

diagnosis of Coats’ disease was<br />

made. Baseline bloods, including<br />

autoimmune and infective panels,<br />

were all normal. Both parents<br />

underwent fundal examination<br />

which was normal.<br />

Considering the patient was<br />

very cooperative, Argon focal<br />

laser was carried out directly to<br />

the telangiectatic vessels in the<br />

right eye. The patient was seen<br />

two weeks later for further focal<br />

laser. A large degree of the exudate<br />

had resorbed with a reduction in<br />

the size of the detachment (Fig<br />

3). Visual acuity had improved to<br />

6/9-2. The patient had a further<br />

final episode of focal laser three<br />

weeks later. Visual acuity improved<br />

and has been maintained at 6/6 in<br />

this eye. Twelve months later the<br />

macula remains flat with peripheral<br />

subretinal fibrosis (Fig 4). There has<br />

been no reoccurrence of subretinal<br />

fluid or exudation.<br />

History<br />

In 1908, George Coats described<br />

“exudative retinitis,” which<br />

was best characterised as<br />

vascular abnormalities with<br />

massive subretinal exudation 1 .<br />

Today, congenital or primary<br />

telangiectasia goes by his name,<br />

Coats’ disease. It consists of<br />

dilated retinal capillaries, microand<br />

macroaneurysms, ischemia,<br />

nonperfusion and retinal vascular<br />

leakage. It typically presents<br />

unilaterally in males.<br />

Four years later, Theodor Leber<br />

described “miliary aneurysms 2 ,”<br />

which were quite similar clinically<br />

to the cases seen by Coats.<br />

The term retinal telangiectasis<br />

was coined by the paediatric<br />

ophthalmologist Algernon Reese<br />

in 1956. He suggested that<br />

Coats’ disease and Lebers’ miliary<br />

aneurysms were one and the<br />

same, occurring either in child or<br />

adulthood 3 .<br />

In 1968, Donald Gass described<br />

a new distinct entity which he<br />

called idiopathic juxtafoveolar<br />

retinal telangiectasis to<br />

differentiate it from Coats’<br />

disease. This resulted in a detailed<br />

classification of all telangiectatic<br />

diseases in 1993 4 .<br />

By 2006, Lawrence Yannuzzi,<br />

using new imaging systems such<br />

as optical coherence tomography<br />

(OCT) and high-speed stereo<br />

angiography, simplified<br />

telangiectasias classification<br />

into two distinct types: Type I,<br />

aneurysmal telangiectasia (Coats’<br />

disease); and Type II, perifoveal<br />

telangiectasia 5 . Now when we<br />

refer to macula telangiectasia or<br />

MacTel, we are often talking about<br />

the common bilateral disease<br />

(Type II) that we see in middleaged<br />

patients.<br />

Aetiology<br />

Coats’ disease is a non-hereditary<br />

ocular disease. The exact<br />

underlying mechanism remains<br />

unknown but a mutation of the<br />

norrin disease protein (NDP) gene<br />

has been proposed 6 , as this results<br />

in a deficiency of the protein<br />

norrin which regulates vascular<br />

development in the developing<br />

retina.<br />

The pathophysiological<br />

processes of Coats’ disease include<br />

the breakdown of the blood-retina<br />

barrier at the level of the vascular<br />

endothelium, predominantly<br />

affecting the capillaries but often<br />

with focal arterial involvement.<br />

Subsequent leakage leads to<br />

aneurysm formation and vessel<br />

blockage with exudation of blood,<br />

lipid and fibrin into the intra<br />

and subretinal spaces 7 . Vascular<br />

endothelial growth factor (VEGF),<br />

which plays an important role in<br />

the formation of normal retinal<br />

vessels and vascular permeability,<br />

is also elevated 8 .<br />

The end result is exudative<br />

retinal detachment. Chronic<br />

detachment can involve the<br />

anterior segment secondarily and<br />

lead to neovascular glaucoma and<br />

blindness 9 .<br />

NEUROTECH AND ARTIFICIAL<br />

intelligence start-up C Light has<br />

developed a non-invasive, fast<br />

and objective retinal eye-tracking<br />

technology to help doctors<br />

quickly and more accurately<br />

diagnose neurological conditions,<br />

such as multiple sclerosis (MS).<br />

Based at the University<br />

of California Berkeley’s tech<br />

incubator, the company was<br />

formed around a tracking<br />

scanning laser ophthalmoscope<br />

(TSLO) developed by C Light cofounder<br />

Dr Christy Sheehy. The<br />

TSLO technology measures the<br />

motion of the eye on a cellular<br />

scale; movements as small as<br />

1/100 the size of human hair.<br />

“The back of your eye is actually<br />

the front of your brain. We use<br />

AI paired with eye tracking to<br />

create a digital fingerprint of<br />

your neurological health with<br />

unprecedented speed and<br />

sensitivity,” said co-founder Dr<br />

Zachary Helft. “Other technologies<br />

use the pupil to track eye motion,<br />

Dr Zachary Helft<br />

but our technique images<br />

the retina for 120 times more<br />

sensitivity… C Light measures eye<br />

motion that has been otherwise<br />

invisible through existing pupil<br />

tracking technologies.”<br />

In this era of digital health, C<br />

Light is creating a completely new<br />

data stream about the status of<br />

brain health via the eye, said Dr<br />

Sheehy. “Our growing databases<br />

and accompanying AI can change<br />

the way we monitor and treat all<br />

neurological diseases for future<br />

generations.”<br />

Patients can be tested in<br />

10 seconds, are free to blink<br />

and don’t require eye drops or<br />

dilation, said Dr Sheehy. Though<br />

testing has begun with MS,<br />

future applications can extend<br />

to Alzheimer’s, Parkinson’s,<br />

Amyotrophic lateral sclerosis (ALS)<br />

and concussions, she added.<br />

Art and optics:<br />

The beautiful and the curious<br />

By Susanne Bradley<br />

In the artist’s self-portrait as Saint Lucy, patron of sight, the eyes on a plate<br />

have been replaced with the medication that cured da Silva from acute<br />

diplopia<br />

(Left) da Silva’s glass eyes were inspired by the museum’s diseased eye<br />

models. The double pupil represents her experience of double vision<br />

THE BRITISH OPTICAL<br />

Association Museum’s<br />

latest exhibition,<br />

Pathos Ocularis – The<br />

Beautiful and the<br />

Curious, was inspired<br />

by artist Iluá Hauck da<br />

Silva’s own experience<br />

of dry eye, diplopia<br />

and photophobia.<br />

Brazilian-born da<br />

Silva, the museum’s<br />

third artist-inresidence,<br />

is an artist<br />

and glassmaker<br />

who specialises<br />

in anatomical<br />

and pathological<br />

symbolism. Drawing<br />

inspiration from her<br />

personal experiences,<br />

the museum’s<br />

collections and from<br />

Iluá Hauck da Silva<br />

medical, scientific and<br />

historical research<br />

conducted in the College of Optometrists’ library, da Silva’s exhibition<br />

creates a modern-day ‘cabinet of curiosities’ dedicated to eyes.<br />

Her residency at the museum resulted when a collector friend<br />

commissioned an eye sculpture, she said. “I thought I’d go to the British<br />

Optical Association Museum, which I had been meaning to visit for<br />

quite some time, to look at eye models and get inspired. My friend and I<br />

booked an appointment with curator Neil Handley and during our visit…<br />

Neil asked to see my work and immediately asked me if I wanted to<br />

exhibit there, which I was delighted about!”<br />

Conceptually, da Silva said her art focuses on the human condition<br />

with body parts and internal organs featuring heavily in her work.<br />

“Growing up in Brazil as the daughter of a doctor, I spent countless time<br />

in hospitals and practices… I have always had an interest in the depiction<br />

of medicine,” she said in the podcast, Through the eyes of an artist.<br />

Developing work about ocular pathology felt particularly pertinent,<br />

said da Silva, as she developed sixth nerve palsy and acute diplopia in<br />

2015, after contracting a severe ear infection which spread. Her residency<br />

and this exhibition offered da Silva an opportunity to creatively explore<br />

eye dryness and photophobia, conditions she still suffers as a result of her<br />

illness. “Creating art that raises awareness of (these conditions), as well<br />

as how to prevent and soothe their symptoms, is not only relevant, but<br />

important to the general public.”<br />

Although the exhibition is a story of recovery, da Silva wanted to<br />

include the word ‘pathos’ in the title as in many cultures it “evokes<br />

suffering and pain, thus prompting empathy and compassion in the<br />

viewer for the sufferer,” she said.<br />

The British Optical Association Museum at the College of Optometrists<br />

in London was founded in 1901. It is the oldest optical museum in the<br />

world with a collection of more than 28,000 items. The Pathos Ocularis<br />

exhibition has been extended due to Covid-19 and will be available to<br />

visit by appointment for a minimum of six weeks once current restrictions<br />

have been lifted in the UK.<br />

US MEDICAL START-UP Rebion has<br />

developed a handheld paediatric vision<br />

scanner to help clinicians screen for<br />

amblyopia.<br />

The Blinq scanner can detect even<br />

subtle strabismus, said inventor Dr David<br />

Hunter, head of ophthalmology at Boston<br />

Children’s Hospital and co-founder of<br />

Rebion. “It can help facilitate earlier<br />

identification of children who need visionsaving<br />

treatment when therapy is likely to<br />

be more effective and reduce unnecessary<br />

referrals to ophthalmologists.”<br />

Dr Hunter and co-inventor Dr<br />

David Guyton, professor of paediatric<br />

ophthalmology at Johns Hopkins Hospital, said eye charts work well for<br />

six-to-seven-year-olds and some five-year-olds but detect amblyopia too<br />

late to fully treat. “Though photo screeners help identify more children at<br />

risk of amblyopia, their accuracy is limited by low detection of strabismus<br />

and high false positive rates,” said Dr Hunter.<br />

Using a polarised laser scan to probe the nerve fibres inside the retina,<br />

Blinq can detect a 1° misalignment between foveas, a sign amblyopia is<br />

present, he explained. “When detected with precision, misalignment of<br />

the foveas identifies essentially 100% of children who have amblyopia,<br />

with fewer false positives compared with photo screeners.” The scanner<br />

also calculates a binocularity score indicating whether a child requires<br />

referral to an ophthalmologist for further investigation.<br />

Two separate studies supporting Blinq’s effectiveness were presented<br />

at the American Academy of Ophthalmology. One, including 80 children,<br />

found Blinq offered 100% accuracy and a false referral rate of just 3%.<br />

FEATURE<br />

By Louise Wood<br />

ELECTRONIC CIGARETTES<br />

(E-CIGARETTES) or vaping devices heat<br />

nicotine, flavours and other chemicals to create<br />

a vapour the user inhales. Vaping has been<br />

marketed as a substitute for tobacco cigarettes to<br />

help smokers kick their addiction, but vaping’s<br />

harmful effects are still largely unknown.<br />

Nicotine is addictive¹ and is found in the<br />

majority of e-cigarettes, potentially making<br />

them as addictive as tobacco, leading the US<br />

Food and Drug Administration to classify<br />

them as “tobacco products”. More worryingly,<br />

a 2019 study found 64% of e-cigarette users<br />

in New Zealand were still smoking tobacco²,<br />

compounding health risks.<br />

Vapour vs tobacco?<br />

The health implications of vaping are starting<br />

to emerge in the literature. A paper published<br />

last year in Respiratory Research, revealed<br />

the bacterial persistence and inflammatory<br />

potential in the lungs caused by e-cigarette<br />

vapour is similar to that found in a tobacco<br />

smoker³. Lead researcher Dr Deirdre Gilpin<br />

said, “Bacteria have long been associated with<br />

the development of lung diseases, such as<br />

bronchitis and pneumonia, where smoking<br />

plays a role. Our study is the first of its kind<br />

which aimed to compare the effect of cigarette<br />

smoke and e-cigarette vapour on key lung<br />

bacteria. E-cigarettes are perceived as being<br />

safer and we are really concerned about that.”<br />

Nicotine in tobacco and e-cigarettes is<br />

associated with cardiovascular risks and<br />

activation of carcinogenic pathways, including<br />

proliferation and angiogenesis, and can<br />

predispose a person to inflammation, infection<br />

and neoplastic disease¹ , ⁴. Studies have also<br />

shown second-hand e-cigarette exposure leads<br />

to the same nicotine blood levels as secondhand<br />

cigarette smoke inhalation⁴. Plus, like<br />

tobacco, e-cigarettes contain high levels of<br />

formaldehyde and other carcinogens, such as<br />

acetaldehyde⁴, and a 2015 study showed an<br />

increase in bacterial virulence and decrease in<br />

host defence with e-cigarettes when compared<br />

with tobacco⁵.<br />

Tobacco and the eye<br />

We have long understood how smoking<br />

tobacco can affect the integrity of the ocular<br />

surface and contribute to the development<br />

of macular degeneration and cataracts.<br />

Chronic smoking has also been linked to<br />

squamous metaplasia and loss of goblet cells<br />

which makes it a significant risk factor in the<br />

development of ocular surface disease⁶ , ⁷.<br />

Smoking promotes molecular and<br />

pathological changes in the body: vascular<br />

inflammation, endothelial cell abnormality,<br />

oxidative and toxic damage⁸. These changes can<br />

lead to the development of macular degeneration<br />

and choroidal neovascular membranes. An<br />

increased prevalence of age-related cataracts<br />

has also been associated with smoking⁹. Several<br />

biological mechanisms have been put forward<br />

for the likely cause including oxidative damage,<br />

chemicals causing lens toxicity and opacity and<br />

increased aldehyde levels in smokers’ blood<br />

which modifies lens proteins.<br />

Vaping and the eye<br />

The effect of vaping on ocular health is still<br />

widely unknown but literature is evolving.<br />

Complaints of eye irritation by users and<br />

bystanders when exposed to vaping aerosols<br />

have been reported but there’s been few peerreviewed<br />

studies. Formaldehyde is a biproduct<br />

of combustion in tobacco and e-cigarettes<br />

and the American National Cancer Institute<br />

warned that when airborne, it can cause a<br />

burning sensation and watering of the eyes.<br />

Another known eye irritant, propylene glycol<br />

is also one of the common base ingredients of<br />

vape e-liquid. Exposure to it can cause ocular<br />

and respiratory irritation 10 .<br />

In the first study of its kind, published in<br />

September 2019, Malaysian researchers looked<br />

at ocular surface data from 21 vapour users<br />

and compared it with 21 non-smokers¹¹. They<br />

looked at the clinical features of the ocular<br />

surface, tear breakup time, fluorescein breakup<br />

time, surface staining, tear meniscus and<br />

Schirmer test scores to evaluate ocular surface<br />

health. Results revealed a significant reduction<br />

in non-invasive tear breakup time, fluorescein<br />

breakup time and tear meniscus height when<br />

compared with non-smokers, while an increase<br />

in vaping voltage increased tear film instability,<br />

indicating vapour users experience moderateto-severe<br />

symptomatic dry eye when compared<br />

to healthy non-smokers.<br />

There has been no specific research into<br />

other ocular side effects of e-cigarettes though<br />

a 2014 study found that nicotine can affect the<br />

eye when ingested¹². In this study, patients<br />

who chewed nicotine gum had significantly<br />

thinner choroids than non-gum chewers,<br />

possibly as a result of reduced ocular blood<br />

flow from the vasoconstrictive properties of<br />

nicotine. Thus, given the presence of nicotine<br />

in most e-cigarettes, it is reasonable to assume<br />

comparable side effects. Similarly, an increased<br />

prevalence of age-related cataracts may be<br />

connected to the toxic chemicals found in<br />

e-cigarette vapour in much the same way<br />

studies have found with tobacco use.<br />

In conclusion<br />

Vaping is becoming a popular craze, especially<br />

among younger people. Vaping products have<br />

been found to transiently reduce blood flow<br />

and oxygen use in the body, and the eye has a<br />

great demand for both. It may take decades to<br />

categorically determine if it is a safer longterm<br />

option than tobacco, but e-cigarette use<br />

is rapidly increasing and preliminary research<br />

shows close similarities between the two.<br />

We should continue to counsel patients on<br />

their lifestyle choices and how these may affect<br />

their health with time. E-cigarettes may be<br />

used as an alternative to tobacco to help with<br />

smoking cessation but should be stopped as<br />

soon as possible to mitigate long-term health<br />

issues, including eye disease.<br />

Vaping legalities in NZ<br />

The Ministry of Health (MoH) ruled<br />

the sale of nicotine-containing vaping<br />

devices was legal in New Zealand in May<br />

2018. Following criticism, the Smokefree<br />

Environments and Regulated Products<br />

(Vaping) Amendment Bill was put to<br />

Parliament on 24 February <strong>2020</strong> to:<br />

• Ban the sale of vaping products to under-18-year-olds<br />

• Stop vaping or smokeless tobacco use in smokefree areas<br />

• Prohibit advertising of vaping products<br />

• Restrict the sale of flavoured vaping products and e-cigarettes<br />

to R-18 specialty stores, and limit general retailers’ sales to three<br />

flavours<br />

• Introduce a product safety system, enabling the MoH to recall,<br />

suspend and issue warnings about vaping products<br />

“The Bill aims to strike the right balance between making sure<br />

vaping is available for smokers who want to use it as a quit tool<br />

for cigarettes while ensuring vaping products are not marketed or<br />

sold to children and young people,” said associate health minister<br />

Jenny Salesa.<br />

But many are concerned restrictions don’t go far enough,<br />

including some who profit from the industry. “Currently, it appears<br />

that anyone will still be able to make a purchase from an overseas<br />

website and have the product shipped to their door, which may<br />

bypass age restrictions and quality controls,” said Paul Williamson<br />

from Shosha, the country’s largest retailer of e-cigarettes.<br />

The government has set a long-term goal of making New<br />

Zealand essentially smokefree by 2025. Submissions on the Bill<br />

closed at the end of April with the Health Select Committee<br />

expected to report back this month.<br />

CXL-assisted infection reduction: a<br />

randomised clinical trial evaluating the<br />

effect of adjuvant CXL on outcomes in<br />

fungal keratitis<br />

Prajna NV, Radhakrishnan N, Lalitha P, Austin<br />

A, Ray KJ, Keenan JD, Porco TC, Lietman TM,<br />

Rose-Nussbaumer J.<br />

Ophthalmology <strong>2020</strong> Feb;127(2):159-166<br />

Design: Randomised control trial of 403 patients<br />

with smear-positive filamentous fungal keratitis.<br />

Eyes were randomised to one of four treatment<br />

arms: (1) topical natamycin 5% alone; (2) topical<br />

natamycin 5% plus cross-linking (CXL); (3) topical<br />

amphotericin B 0.15% alone; or (4) topical<br />

amphotericin B 0.15% plus CXL.<br />

Outcome: There was no difference in culture<br />

positivity 24 hours after commencing treatment<br />

between those randomised to amphotericin or<br />

natamycin, regardless of whether they received<br />

CXL. Those that received CXL had worse visual<br />

acuity (VA) outcomes: best corrected VA was<br />

0.22 logMAR (2.2 Snellen lines) worse at three<br />

weeks and 0.32 logMAR (3.2 Snellen lines) worse<br />

at three months. There was no difference in<br />

infiltrate, scar size or adverse events between<br />

the groups.<br />

New RP therapy<br />

SCIENTISTS HAVE DEVELOPED a new gene<br />

therapy approach that could treat retinitis<br />

pigmentosa (RP).<br />

Genetics, virology and ophthalmology<br />

researchers from Trinity College Dublin and<br />

University College London (UCL) teamed up<br />

to deliver a normal, functioning copy of the<br />

RP2 gene, which provides instructions for<br />

making a protein essential for normal vision,<br />

into ‘mini retinas’, engineered from stem cells<br />

and containing a defective form of the gene.<br />

The mini retinas successfully took up the<br />

functioning RP2 gene and produced the<br />

essential protein resulting in significant<br />

improvement, said PhD researcher Ciara<br />

Shortall, co-author of the study published in<br />

Stem Cell Reports.<br />

“It is an important development that we<br />

can now reproduce so many elements of<br />

inherited disease using these mini retinas.<br />

It makes it possible for us to study in<br />

detail why people go blind and try to find<br />

ways to prevent blindness,” said Professor<br />

Michael Cheetham from UCL which led the<br />

development of the mini retinas to road-test<br />

the gene therapy.<br />

Limitations: This study was performed in<br />

India, where there is a high incidence of fungal<br />

keratitis often associated with agricultural<br />

exposure. The spectrum of organisms<br />

responsible for fungal keratitis in New<br />

Zealand and other developed countries may<br />

be different and exhibit dissimilar response<br />

patterns to treatment. As the study included<br />

eyes with fungal keratitis due to multiple<br />

filamentous organisms, only small numbers<br />

of individual fungi were included making it<br />

difficult to detect the presence of a benefit for<br />

CXL for any particular organism.<br />

Comment: Fungal keratitis remains a<br />

challenging condition to manage. Despite the<br />

recent interest in CXL as a treatment option in<br />

microbial keratitis, this article suggests there<br />

is no benefit in using adjuvant CXL in the<br />

treatment of filamentous fungal keratitis and it<br />

may result in worse visual outcomes.<br />

Efficacy of amniotic membrane<br />

transplantation for the treatment of corneal<br />

ulcers<br />

Schuerch K, Baeriswyl A, Frueh BE, Tappeiner C<br />

Cornea <strong>2020</strong> Apr;39(4):479-483<br />

Design: Retrospective analysis of 149<br />

patients treated with amniotic membrane<br />

transplantation (AMTX) for refractory corneal<br />

ulcers. The underlying cause of the ulcers<br />

were diverse, including herpetic, bacterial and<br />

rheumatic disease, previous corneal surgery,<br />

bullous keratopathy, limbal stem cell deficiency<br />

and neurotrophic ulcers.<br />

Outcome: The mean duration between ulcer<br />

onset and AMTX was 42 ±46 days. However,<br />

it occurred much earlier for cases following<br />

chemical injury (mean 14 days) compared to<br />

bacterial keratitis (mean 65 days). In 70% of<br />

cases, a single AMTX was sufficient to achieve<br />

epithelial closure: 21% within the first month,<br />

40% within one to three months and 9% within<br />

three to six months. Epithelial closure was also<br />

achieved in 41% and 40% respectively of those<br />

undergoing a second and third AMTX. The<br />

highest epithelial closure rates were found in<br />

neurotrophic, herpetic and bacterial ulcers (93%,<br />

85% and 80% respectively). The lowest success<br />

rates were found in ulcers after corneal surgery<br />

or associated with rheumatic disease (52% and<br />

57% respectively).<br />

Limitations: This was a retrospective study<br />

with no control group.<br />

Comment: Amniotic membranes contain a high<br />

concentration of fibroblast growth factors and<br />

cytokines. It forms a mechanical barrier and<br />

promotes epithelial recovery while suppressing<br />

inflammation. It offers a valuable treatment<br />

option to promote corneal epithelial healing<br />

in refractory ulcers particularly neurotrophic,<br />

herpetic and bacterial ulcers. Even if not initially<br />

successful, a second or even third AMTX may<br />

result in epithelial healing.<br />

A case-control study of keratoconus risk<br />

factors<br />

Moran S, Gomez L, Zuber K, Gatinel D.<br />

Cornea <strong>2020</strong> Jun;39(6):697-701<br />

Design: Single centre, prospective case control<br />

study evaluating 202 patients with keratoconus<br />

and 355 controls. Patients were surveyed<br />

regarding their ophthalmic and medical<br />

histories and data regarding multiple variables<br />

was gathered and analysed.<br />

Outcome: After multivariate analysis, the<br />

following factors showed significant results:<br />

eye rubbing with knuckles or fingertips, history<br />

of dry eye, male sex, night-time work, increased<br />

screen time, prone and side sleep position were<br />

all associated with keratoconus. Conversely,<br />

sleeping supine was found to be a protective<br />

factor. No link was found between a family<br />

history of keratoconus and development of the<br />

condition.<br />

Limitations: Most of the data required for this<br />

study was reliant on patients’ history which is<br />

dependent on patient recollection and subject<br />

to recall bias, and there was a relatively small<br />

number of patients included.<br />

Comment: The high prevalence of keratoconus<br />

in New Zealand is well known. Despite great<br />

improvements in diagnosis and management<br />

in recent years, the underlying pathogenesis<br />

is still a subject of debate. Eye rubbing has<br />

long been implicated as an exogenous<br />

environmental factor in the development of<br />

keratoconus, however this study also implicates<br />

other associations including sleep position,<br />

night-time work and screen time. These<br />

associations may merit further investigations<br />

and may guide future advice to patients at risk.<br />

EYLEA ® (aflibercept) EYLEA is used in ophthalmology. Prescription medicine. 40 mg/mL solution for intravitreal injection containing aflibercept. INDICATIONS: EYLEA (aflibercept)<br />

is indicated in adults for the treatment of neovascular (wet) age-related macular degeneration (wet AMD), visual impairment due to macular oedema secondary to central retinal vein<br />

occlusion (CRVO), visual impairment due to macular oedema secondary to branch retinal vein occlusion (BRVO), diabetic macular oedema (DME), visual impairment due to myopic choroidal<br />

neovascularisation (myopic CNV). DOSAGE REGIMEN AND ADMINISTRATION: 2 mg aflibercept (equivalent to injection volume of 50 µL). The interval between doses injected into<br />

the same eye should not be shorter than one month. Once optimal visual acuity is achieved and/or there are no signs of disease activity, treatment may then be continued with a treatand-extend<br />

regimen with gradually increased treatment intervals to maintain stable visual and/or anatomic outcomes. If disease activity persists or recurs, the treatment interval may be<br />

shortened accordingly. Monitoring should be done at injection visits. There is limited information on the optimal dosing interval and monitoring interval especially for long-term (e.g. >12<br />

months) treatment. The monitoring and treatment schedule should be determined by the treating ophthalmologist based on the individual patient’s response. If visual and anatomic outcomes<br />

indicate that the patient is not benefiting from continued treatment, EYLEA should be discontinued. For wet AMD: Based on the physician’s judgement of visual and/or anatomic outcomes,<br />

the treatment interval may be maintained at two months or further extended using a treat-and-extend dosing regimen, by increasing injection intervals in 2- or 4-weekly increments while<br />

maintaining stable visual and/or anatomic outcomes. If visual and/or anatomic outcomes deteriorate, the treatment interval should be shortened to a minimum of four weeks based on<br />

anatomical and/or visual outcomes. Generally, once optimal visual acuity is achieved and/or there are no signs of disease activity, the treatment interval may be adjusted based on visual and/<br />

or anatomic outcomes. Treatment intervals greater than four months (16 weeks) between injections have not been studied. For CRVO: Treatment is initiated with one injection per month for<br />

three consecutive months. After the first three monthly injections, the treatment interval may be adjusted based on visual and/or anatomic outcomes. For BRVO: Treatment is initiated with<br />

one injection per month for three consecutive months. After the first three monthly injections, the treatment interval may be adjusted based on visual and/or anatomic outcomes. For DME:<br />

Treatment is initiated with one injection per month for five consecutive months, followed by one injection every two months. After the first 12 months, the treatment interval may be adjusted<br />

based on visual and/or anatomic outcomes. For myopic CNV: EYLEA treatment is initiated with one injection of 2 mg aflibercept (equivalent to 50 µL). Additional doses should be administered<br />

only if visual and/or anatomic outcomes indicate that the disease persists. Recurrences are treated like a new manifestation of the disease. CONTRAINDICATIONS: Known hypersensitivity<br />

to aflibercept or excipients; ocular or periocular infection; active severe intraocular inflammation. PRECAUTIONS: Endophthalmitis, increase in intraocular pressure; immunogenicity;<br />

arterial thromboembolic events; bilateral treatment; risk factors for retinal pigment epithelial tears; treatment should be withheld in case of rhegmatogenous retinal detachment, stage 3 or 4<br />

macular holes, retinal break, decrease in best-corrected visual acuity of ≥30 letters, subretinal haemorrhage or intraocular surgery; treatment not recommended in patients with irreversible<br />

ischemic visual function loss; population with limited data (diabetic macular oedema due to type 1 diabetes, diabetic patients with HbA1c >12%, proliferative diabetic retinopathy, active<br />

systemic infections, concurrent eye conditions, uncontrolled hypertension, in myopic CNV there is no experience in the treatment of non-Asian patients, previous treatment for myopic CNV<br />

and extrafoveal lesions), see full Data Sheet for effects on fertility, pregnancy, lactation, effects on ability to drive or use machines. INTERACTIONS: No formal drug interaction studies have<br />

been performed. ADVERSE EFFECTS: Very common: conjunctival haemorrhage, visual acuity reduced, eye pain. Common: retinal pigment epithelial tear, detachment of retinal pigment<br />

Understanding<br />

Charles Bonnet Syndrome<br />

By Naomi Meltzer<br />

IMAGINE BEING A passenger in a car and a<br />

brick wall suddenly appears in front of you, or<br />

rows of brown, high-rise buildings start to sway<br />

and bend gracefully towards you. Perhaps, as<br />

you prepare for bed, you pull back your covers<br />

and find a brown, furry thing there. You’re not<br />

afraid because although you have no pets,<br />

you have seen this furry thing quite frequently<br />

recently.<br />

These are real examples of Charles Bonnet<br />

Syndrome (CBS) as told to me by sane, lucid and<br />

sometimes, understandably, extremely anxious<br />

people.<br />

Another patient of mine recalled finding<br />

her retirement village garden planted with<br />

gloriously coloured flowers and even thanked<br />

the gardener before returning to her apartment<br />

to find the flowers had disappeared. While<br />

another said she saw an army of Roman-like<br />

soldiers, marching around the room before<br />

disappearing into the ceiling. Her husband<br />

laughed and called her a “silly old ding-bat”.<br />

Though CBS hallucinations are rarely the<br />

stuff of horror movies, they are confusing and<br />

worrying for patients, leading many to question<br />

their own sanity.<br />

Patient hallucination description, involving Lilliputian visions, which<br />

are commonly seen in patients suffering from CBS³<br />

The syndrome is named after the 18thcentury<br />

Swiss naturalist and philosopher<br />

Charles Bonnet who first described the visual<br />

hallucinations in 1760, after his 87-year-old<br />

grandfather began telling him what he’d been<br />

seeing. Bonnet’s grandfather was thought<br />

to have macular degeneration and possibly<br />

cataracts and, until quite recently, it was<br />

thought that CBS only occurred in conjunction<br />

with macular degeneration. Recent research,<br />

however, indicates it’s associated with a loss of<br />

a patient’s visual ability to distinguish an object<br />

from its background, which can occur with<br />

many visual or neurological conditions.<br />

Mary Lou Jackson, an ophthalmologist and<br />

director of the Vision Rehabilitation Center at<br />

Harvard Medical School, has published several,<br />

frequently quoted papers investigating CBS<br />

in glaucoma patients. Her research indicates<br />

CBS occurs in similar frequency in glaucoma<br />

patients to other eye and neurological<br />

conditions and also concluded its appearance<br />

is most closely linked to contrast sensitivity loss<br />

rather than visual acuity.<br />

In CBS, a person often sees complex visual<br />

hallucinations such as patterns like brickwork,<br />

“Not one, but a whole herd of elephants, blocking the main street of Taupo…”<br />

said Gael Spence, sharing one strange, realistic hallucination 2<br />

basketwork or lace, superimposed on everyday<br />

items like walls or furniture, or people,<br />

animals or inanimate objects, not necessarily<br />

identifiable as something previously seen. The<br />

defining elements which differentiate CBS from<br />

other hallucinatory conditions include:<br />

l Well-formed visual hallucinations the patient<br />

can describe, rather than vague flashes of light<br />

l Insight into the unreal nature of the<br />

hallucination, especially after it is explained to<br />

the patient. For example, a patient told me how<br />

on waking she’d found papers scattered on her<br />

bedroom floor. She knew there was no open<br />

window and no pile of papers that could be<br />

blowing around, yet she still got out of bed to<br />

pick them up before they disappeared<br />

l Some degree of vision loss before<br />

experiencing the hallucinations<br />

l No other previously diagnosed psychiatric<br />

or neurological diagnoses to explain the<br />

hallucination, i.e. the patient appears to have<br />

no other sign of dementia or cognitive change<br />

CBS hallucinations are thought to<br />

originate in the brain. Many attribute them<br />

to deafferentation causing a lack of true<br />

visual input into the<br />

visual cortex, which<br />

results in a release<br />

phenomenon analogous<br />

to phantom pain after<br />

limb amputation. Others<br />

simply describe the<br />

phenomenon as the<br />

brain trying to fill in the<br />

gaps in a patient’s vision,<br />

where, without visual<br />

input, unregulated visual<br />

cortex activity emerges<br />

as hallucinations.<br />

28 | NEW ZEALAND OPTICS JULY <strong>2020</strong>


EDUCATION<br />

The exacerbation of social isolation<br />

Regardless of the origin, it is well documented<br />

that the occurrence of visual hallucinations<br />

increases at times of sensory deprivation,<br />

such as when a person is socially isolated or<br />

in the early hours of the morning when the<br />

sufferer is awake, but there is nothing much<br />

else happening. Usually it disappears when<br />

distractions, such as the radio or television, or<br />

some new activity are initiated.<br />

The prevalence of CBS in elderly patients is<br />

reported to be anywhere from 0.5% to 40%;<br />

the high variance due to CBS frequently being<br />

attributed to mental illness. Generally, however,<br />

it is thought to affect about 30% of patients<br />

with some form of vision loss. But it is believed<br />

to be heavily under reported due to patient<br />

anxiety about the onset of dementia and<br />

negative comments from family, friends and<br />

medical personnel.<br />

My experience, from talking to almost all of<br />

my low vision patients about CBS, is that this<br />

anxiety is warranted. It does not matter how<br />

sensitively I initiate the conversation, a large<br />

proportion of accompanying family and indeed<br />

patients, will immediately make some sort of<br />

joke or negative comment. For those who have<br />

experienced CBS however, I can usually sense a<br />

change in body language immediately.<br />

A simple question such as, “has<br />

anything like that ever happened<br />

to you?” can result in a myriad<br />

of responses from tears of relief<br />

to embarrassment or anger that<br />

nobody took them seriously when<br />

they tried to speak of it.<br />

Although CBS is usually associated Charles Bonnet<br />

with visual hallucinations, it also occurs<br />

with other sensory deprivation. There are<br />

similar phenomena reported for the olfactory<br />

and auditory senses. Olfactory deprivation has<br />

been shown to result in functional changes<br />

and even structural changes, such as decreased<br />

mucosa thickness in the nose and possible<br />

changes in the number of receptor neurons.<br />

In the auditory pathways, tinnitus is defined<br />

as a perception of a sound that is not related<br />

to an acoustic source or electrical stimulation.<br />

Usually, but not always, this is associated<br />

with hearing loss. It can range from simple<br />

sounds to complex musical or even verbal<br />

hallucinations. Was Beethoven experiencing<br />

auditory CBS?<br />

One experience of a 99-year-old widow<br />

continues to resonate with me. Fiercely<br />

independent and very lucid, this lady had<br />

resisted moving out of her home into a rest<br />

home for a long time. Three weeks after she<br />

gave in and moved, and before staff<br />

had really got to know her, she<br />

noticed a man standing by her bed<br />

in the early hours of the morning.<br />

As she watched he floated up into<br />

the top corner of her wardrobe and<br />

disappeared. He appeared several<br />

times over the next few weeks and<br />

unwilling to speak to staff about it for fear<br />

that they would write her off as a dementia case,<br />

she concluded it was the ghost of a previous<br />

occupier and continued to worry he was trying<br />

to tell her something. As she related this to me,<br />

her younger sister who was hearing all this for<br />

the first time was clearly aghast at what must<br />

have been a frightening experience alone in<br />

this new place. She asked her sister, was it her<br />

husband who appeared by her bed leaning<br />

over her? “Oh no” said the 99-year-old with a big<br />

smile, “he was much more handsome.”<br />

Residual refractive error after<br />

cataract surgery<br />

By Drs Ye Li and Mo Ziaei<br />

CATARACT SURGERY IS the most<br />

commonly performed operation globally,<br />

with over 30,000 performed per annum in<br />

New Zealand. The surgery has transformed<br />

into a refractive procedure in recent years,<br />

with patients often expecting the surgery<br />

to minimise their dependence on glasses.<br />

However, residual refractive error following<br />

surgery is still relatively common. In 2015,<br />

postoperative visual and refractive outcomes<br />

in New Zealand were found to be comparable<br />

to international standards¹, which aims to<br />

have 85% of patients achieve a spherical<br />

equivalent (SE) within 1 dioptre (D) and 55%<br />

of patients within 0.5D of the intended target².<br />

This translates into more than 4,500 patients<br />

a year with a residual refractive error of >1D<br />

following surgery every year.<br />

Multidisciplinary care of the cataract patient<br />

is continuously evolving to meet postoperative<br />

refractive benchmarks, with the development<br />

of an assortment of intraocular lenses (IOLs),<br />

advanced biometric measurements, modern<br />

IOL calculation formulae and the improvement<br />

in surgical options available to perform<br />

postoperative enhancement.<br />

Current cataract surgery techniques<br />

Phacoemulsification remains the gold standard<br />

technique for cataract surgery. It has replaced<br />

previously conventional methods such as<br />

intracapsular cataract extraction (ICCE),<br />

extracapsular cataract extraction (ECCE)<br />

and manual small incision cataract surgery<br />

(MSICS), due to advantages in visual outcomes<br />

and a lower complication rate.<br />

Recently, the femtosecond laser has been<br />

employed for use in cataract surgery due<br />

to theoretically higher precision in surgical<br />

incisions, more predictable capsulotomy<br />

and reduced ultrasound energy. There is a<br />

sparsity of large, long-term studies comparing<br />

femtosecond laser-assisted cataract surgery<br />

to phacoemulsification, however, at this<br />

stage, there is no compelling evidence to<br />

suggest significant differences in refractive<br />

or visual outcomes. One European registry<br />

study suggests that femtosecond laserassisted<br />

cataract surgery has a similar<br />

intraoperative complication profile compared<br />

with phacoemulsification but a higher rate of<br />

postoperative refractive surprise due to corneal<br />

oedema and posterior capsule opacification.<br />

and anterior capsular contraction with circumferential fibrosis (right)<br />

Minimising preoperative sources of error<br />

Recognising potential sources of postoperative<br />

refractive error is instrumental in achieving<br />

desirable postoperative outcomes. In most<br />

cases, a detailed ocular history, thorough<br />

examination and appropriate imaging is<br />

adequate for detecting significant risk factors<br />

that converge to lead to inappropriate IOL<br />

power selection. Such risk factors include<br />

ocular surface disease (OSD), contact lens<br />

wear, prior refractive surgery, keratoconus,<br />

astigmatism and extremes of axial length<br />

(AL).<br />

Ocular surface disease<br />

OSD is an underdiagnosed condition that has<br />

a prevalence of 5-50% globally. One study of<br />

patients presenting for cataract assessment<br />

revealed that 77% of cases exhibited corneal<br />

fluorescein staining, while only 22% had a<br />

formal diagnosis of dry eye. Untreated OSD<br />

resulting in hyperosmolarity and tear film<br />

instability, compromises the quality of the<br />

refractive surface, which directly affects<br />

keratometric measurements and can lead to<br />

erroneous measurements of keratometric<br />

astigmatism. Errors in measured astigmatism<br />

can be significant in IOL power calculations,<br />

particularly for astigmatic correcting (toric)<br />

IOLs.<br />

Error due to OSD can be avoided<br />

through vigilant assessment and subsequent<br />

comprehensive treatment of the ocular surface<br />

for at least four weeks, at which point repeat<br />

biometry measurements will be necessary.<br />

Treatment should involve frequent lubrication<br />

and lid hygiene with adjuvant treatment<br />

such as topical steroid and oral azithromycin<br />

reserved for recalcitrant cases.<br />

Contact lens wear<br />

Contact lens wearers are also subject to an<br />

increased risk of postoperative refractive<br />

error. Extensive contact lens wear leading<br />

to prolonged hypoxia and subsequent<br />

corneal warpage can influence the<br />

accuracy of keratometric measurements³.<br />

Discontinuation of contact lens wear for<br />

a minimum of two to three days for soft<br />

lens and one to two weeks for rigid gas<br />

permeable lenses, prior to biometric and<br />

topographic measurements, is essential. A<br />

more prolonged discontinuation period may<br />

be required if the preoperative biometric<br />

and topographic measurements still exhibit<br />

evidence of corneal warpage, and multiple<br />

visits and measurements may be required in a<br />

small proportion of patients.<br />

Refractive surgery<br />

Prior refractive surgery, such as laser in<br />

situ keratomileusis (LASIK), laser epithelial<br />

keratomileusis (LASEK), photorefractive<br />

keratectomy (PRK) and radial keratotomy<br />

(RK), can instigate multiple errors in<br />

IOL power calculations due to erroneous<br />

preoperative keratometric measurements⁴.<br />

Traditional topography and biometry<br />

devices only measured the anterior radius<br />

of curvature while assumptions were made<br />

about the posterior cornea contribution<br />

for the index of refraction. After all types<br />

of refractive surgery, with the exception of<br />

RK where anterior-posterior changes are<br />

relatively proportional, these assumptions<br />

are violated. If not accounted for, patients<br />

with myopic refractive surgery generally<br />

experience a hyperopic shift following<br />

cataract surgery and a myopic surprise<br />

can be expected after hyperopic refractive<br />

surgery. Development of multiple modern<br />

IOL formulae and supplementary adjustment<br />

tools have tailored calculations to account for<br />

these factors, but it remains prudent upon<br />

the referring optometrist and the cataract<br />

surgeon to actively ask for a history of<br />

refractive surgery.<br />

FOR ALL EYE CARE PROFESSIONALS<br />

indicating ocular surface disease<br />

Keratoconus<br />

Other conditions resulting in corneal<br />

irregularities, such as corneal ectasia, present<br />

similar challenges in IOL calculations. Accurate<br />

biometry measurements are notably difficult to<br />

obtain in patients with keratoconus, especially<br />

in those with severe disease who are more<br />

prone to cataract formation due to concurrent<br />

atopy and possible previous topical steroid<br />

use. Displacement of the steep axis causing<br />

misalignment with the visual axis and the<br />

presence of severe corneal distortion induces<br />

error in keratometric measurements and<br />

effective lens position, typically resulting in an<br />

underestimated IOL power and postoperative<br />

hyperopia. In preoperative assessments, vigilant<br />

detection for keratoconus, accurate staging and<br />

obtaining an understanding of the patient’s<br />

disease status and possible progression can be<br />

essential in minimising postoperative refractive<br />

error which may have accentuated downstream<br />

effects due to future interventions that may be<br />

required for the treatment of the ectatic process<br />

(eg. keratoplasty).<br />

Astigmatism<br />

Astigmatism can be challenging to address<br />

and accurate assessment of its magnitude<br />

is helpful in surgical planning. Previous<br />

research has revealed the residual refractive<br />

error is more common in individuals with<br />

higher levels of preoperative astigmatism.<br />

Varying degrees of astigmatism are managed<br />

differently. Patients with 1D often benefit from<br />

a toric IOL⁵. A recent meta-analysis showed<br />

that toric IOLs are superior in astigmatism<br />

correction compared to corneal incisions, but<br />

these lenses need to be placed accurately on<br />

the steep axis in order to effectively neutralise<br />

astigmatism⁶.<br />

Axial length and modern formulae<br />

Patients with extremes of AL are also more<br />

prone to refractive surprise. The use of<br />

modern biometry devices that use optical<br />

coherence tomography (OCT) to generate<br />

Fig 3. LASIK enhancement in a patient with hyperopic<br />

refractive surprise following routine cataract surgery<br />

accurate AL measurements as well as modern<br />

formulae has led to a significant reduction<br />

in refractive error. The recently introduced<br />

formulae analyse multiple biometric<br />

parameters such as AL, keratometry, lens<br />

thickness, anterior chamber depth and whiteto-white<br />

distance, and employ regression<br />

models or artificial intelligence to better<br />

predict the postoperative position of the IOL<br />

(effective lens position) and improve refractive<br />

outcomes. In one recent study, the refractive<br />

accuracy was found to be most challenging to<br />

achieve in short eyes


BUSINESS<br />

Best practice.<br />

Made easy.<br />

Business post-Covid-19: our new normal<br />

By David Pearson<br />

THE COVID-19 PANDEMIC will likely change<br />

the way we do business for a long time<br />

to come. For most businesses’ turnover is<br />

down and owners are having to deal with<br />

an environment that is constantly changing,<br />

affecting inventory requirements (especially<br />

those reliant on imports) and staffing capacity.<br />

Maintaining profitability or, in some cases<br />

viability and liquidity, can prove challenging.<br />

Here are some key elements to increase the<br />

likelihood of success.<br />

Short-term cash flow forecast<br />

Prepare a 13-week cash flow forecast. This<br />

is often an eye-opening exercise and will<br />

effectively capture most entities’ business cycles.<br />

The forecast will help navigate stormy waters<br />

in the near-term, as it will highlight shortfalls<br />

in necessary cash balances. Maintaining an<br />

up-to-date forecast will allow you to easily<br />

identify if and when there is an upcoming risk of<br />

running out of cash and will reveal if borrowing<br />

requirements fall short of actual availability from<br />

credit lines. You will need to ensure any forecast<br />

is subject to regular revisions in light of Covid-19<br />

and its ongoing impact on the market.<br />

Being in a position to identify when cash<br />

may be short puts you on the front foot to<br />

source more capital or organise new payment<br />

arrangements for extended loan facilities, tax<br />

payment plans, starting conversations about<br />

supplier arrangements and/or liaising with<br />

landlords regarding rent relief.<br />

Monitor actual against forecast<br />

Cash is king! A business can be reporting<br />

profits but still have trouble meeting current<br />

obligations to lenders and key creditors. Having<br />

accurate, monthly financial statements can<br />

prove invaluable in keeping on top of where<br />

your cash flow is at in real time. This also helps<br />

you to fully utilise short-term cash flow to its<br />

full capacity, allowing you to identify problems<br />

that may develop as patients become slower<br />

to pay or don’t pay at all. Some problems<br />

may also not be immediately recognised,<br />

including changes in product/service demands,<br />

increasing overhead costs, use of obsolete<br />

pricing methods or increasing competition due<br />

to industry adaptation.<br />

Where possible review all non-essential<br />

expenses and capital projects to identify<br />

opportunities to free up cash surpluses quickly<br />

if needed. Reviewing inventory levels cannot<br />

be underestimated as post-Covid optimums<br />

may be quite different to pre-Covid optimums<br />

and these changes may also free up working<br />

capital. Finally, ensure your patients clearly<br />

understand your payment terms which must<br />

be targeted at minimising credit terms.<br />

Learning by doing<br />

When faced with great uncertainty, we<br />

have three options: remove the uncertainty<br />

and proceed; proceed anyway and adjust<br />

as necessary; or do nothing. If we assume<br />

option one is unrealistic and option three is<br />

unacceptable, we’re left with only one option<br />

– take action, learn and adapt. The objective<br />

of adaptive management is to provide a<br />

framework that drives action now, despite<br />

uncertainty. The goal is not necessarily a<br />

predetermined target, at least not initially, it’s<br />

about achieving incremental change: take<br />

a small step, reflect, learn, adjust and take<br />

another small step.<br />

Adaptation goes past simply responding to<br />

disruptive events; it also means seeking out<br />

and seizing opportunities created by market<br />

forces. At times like this, it’s this sort of iterative<br />

decision making that should be the foundation<br />

of your strategic planning.<br />

Short-term action plan<br />

The potential output of a short-term action<br />

plan should be a succinct, fit-for-purpose plan<br />

that prioritises the what, who and when for<br />

your business, and can be used as a roadmap<br />

in upcoming months as well as a discussion<br />

document for sharing with stakeholders. The<br />

following areas should be noted:<br />

l Current government rules and requirements<br />

for your business<br />

l What you know for certain, what you can be<br />

doing now to prepare<br />

l Short-term goals<br />

l SWOT analysis<br />

l Overall solvency<br />

l Working capital needs<br />

l Supply chain continuity, logistics<br />

l Patients and sales<br />

l Employment issues and business structure<br />

l Finance and funding (cashflows, plans etc.)<br />

Ideally, a short-term action plan should focus<br />

on a 90-day time period that lends itself to<br />

becoming the basis for a reviewed annual plan.<br />

It’s important you not only focus on the threats<br />

and weaknesses of the current market, but<br />

also identify opportunities to reinvent, grow or<br />

diversify your business offerings and operating<br />

style. While you may not be in the right place<br />

financially to take advantage of these now, they<br />

could possibly be worked into your long-term,<br />

more growth-orientated action plan.<br />

While the above tools will help ensure<br />

your business is well placed to adapt to this<br />

uncertain operating landscape, it’s paramount<br />

the planning put in place is robust and brutally<br />

honest. There is no room for rose-coloured<br />

glasses here! Remember, your business is there<br />

to serve you, not for you to serve it; being<br />

aware of what you need to get out of the<br />

business will provide direction and guidance<br />

for forward momentum.<br />

Continued from p31<br />

When counselling patients regarding<br />

postoperative residual refractive error,<br />

it is important to acknowledge the<br />

patient’s concern and ensure preoperative<br />

measurements are reviewed to confirm the<br />

correct IOL was implanted. After ensuring<br />

the correct IOL was implanted, it is also<br />

important to reiterate that residual refractive<br />

error is not an uncommon issue. Patient<br />

reassurance regarding the availability of<br />

solutions can eliminate potential distress<br />

and dissatisfaction, but before committing<br />

to an enhancement procedure, it is vital to<br />

ensure the patient understands the visual<br />

consequences, particularly if they are left<br />

myopic after surgery and are enjoying the<br />

benefits of unintended “monovision”.<br />

Conclusion<br />

Advances in cataract surgery have enabled<br />

patients to achieve improved visual<br />

outcomes, with the rise of more IOL options,<br />

surgical accessories and improved precision<br />

in IOL power calculation . Despite such<br />

developments, postoperative refractive error<br />

remains relatively common.<br />

Refractive error after cataract surgery<br />

can be minimised through recognition<br />

and correction of potential risk factors. In<br />

instances where the amount of refractive<br />

error is perceived as unacceptable,<br />

enhancement procedures can provide<br />

excellent refractive and visual outcomes.<br />

Whilst perfection in postoperative<br />

refraction cannot yet be guaranteed,<br />

achieving patient satisfaction is absolutely<br />

within reach through patient-centred care,<br />

appropriate counselling and adequate<br />

utilisation of enhancement procedures<br />

following cataract surgery.<br />

Vision monitor app<br />

UK-BASED OKKO Health has launched a new<br />

app allowing eye care practitioners (ECPs) to<br />

monitor their patients’ eyes remotely.<br />

Developed by vision scientists, optometrists<br />

and ophthalmologists, the app instructs<br />

patients to tap on visual cues and pattern<br />

anomalies to assess their visual acuity and<br />

contrast sensitivity. It uses a secure online<br />

portal for ECPs to access readings and identify<br />

patients needing help.<br />

Founder Dr Stephanie Campbell said she<br />

is optimistic about the positive impact the<br />

software will have on vulnerable patients. “With<br />

our app, they can now track key indicators of<br />

De Rigo’s early Christmas<br />

their eye health from the safety of their own<br />

homes. I have no doubt this technology will be<br />

a sight-saver for many.”<br />

DE RIGO HAS launched a Christmas promotion to help independents tempt customers back into<br />

practices while creating a bit of fun and reward participating staff.<br />

“Covid-19 has been very challenging for everyone, however<br />

New Zealand has led the world with its recovery,” said De<br />

Rigo’s Chris Hanley. “De Rigo NZ is running a Christmas<br />

promotion to help continue that recovery by giving practice<br />

staff an added incentive to gain extra Christmas gifts.”<br />

The promotion is running for the next six months and the<br />

rewards catalogue is full of local brands and products which<br />

will also support local businesses, he said.<br />

To be eligible, a practice must stock four De Rigo brands<br />

with a minimum of 12 pieces in each brand. The campaign<br />

runs from 1 June to 30 November <strong>2020</strong>.<br />

When marketing and a crisis don’t mix!<br />

By Siu-Yin Shing<br />

BEFORE EYEWEAR, I worked in PR and marketing for the fashion<br />

sector, so I understand how essential it is for businesses to broadcast<br />

the right messages in today’s social media world because, if you get it<br />

wrong, people are quick to voice their opinion. So, I was curious, when<br />

I saw how many people were angry at cut-price, online frame and lens<br />

company Polette Eyewear. “Ooooo, what did they do to upset their<br />

followers?” I thought.<br />

It wasn’t hard to spot the issue.<br />

Right now, we are in the worst pandemic of<br />

our lifetime. Covid-19 is on the news every day.<br />

Different countries are tackling it (or not) in all<br />

sorts of different ways but wherever you are,<br />

there is no way of not knowing about it.<br />

In the UK, the news regularly reported there<br />

were not enough protective medical supplies for<br />

healthcare workers as cases continued to rise.<br />

It became a top priority to source and deliver<br />

enough masks and sanitisers and other personal<br />

protective equipment (PPE) for health staff on<br />

the frontline, fighting the virus to keep their<br />

patients alive.<br />

Riding the back of this, at the beginning<br />

of the outbreak in Europe in March, Polette<br />

thought it was a good idea to run a See clear,<br />

stay safe promotion giving away two free face<br />

masks with every purchase. The response was<br />

immediate and angry, upsetting about 95% of<br />

the company’s followers on social media.<br />

People felt they were at best insensitive to<br />

the pandemic; at worst, helping to fuel it. Many<br />

asked, “Why give masks to ordinary people like<br />

us when medical staff don’t even have enough<br />

and they are the ones battling Covid-19,” and,<br />

“Why not donate what you have to them?” Both<br />

very valid questions!<br />

Polette’s ill-considered pandemic promotion<br />

Was Polette insensitive?<br />

After SARS in 2002, almost everyone across Asia adopted the habit of<br />

wearing a mask for minor things like a common cold. Wearing a mask<br />

is normal practice; it’s no big deal. But this is not the case in all cultures.<br />

Polette has factories in China and when the outbreak first happened,<br />

masks were hard to find, so many businesses in Hong Kong, for example,<br />

gave out free masks to the general public as a marketing tool.<br />

So I don’t think Polette purposely meant to be<br />

insensitive, but their marketing team should have<br />

done more research and a lot more thinking and<br />

discussing before they jumped into grab some<br />

publicity off the back of the pandemic.<br />

Fuelling the furore<br />

The public reaction was so negative, Polette<br />

made two separate statements explaining its<br />

reasons for the campaign.<br />

The first apologised for any<br />

‘miscommunication’ then rattled on about caring<br />

for its staff in China and the self-proclaimed<br />

good work the company was doing to provide<br />

masks to all, and that the company had values<br />

and heart, “…maybe you considered it misplaced<br />

tonight but if you follow us, you should by now<br />

know where our hearts stand! We thank you for<br />

your support and sorry for hurting all of your<br />

feelings! Polette loves you.”<br />

Instead of quelling the rage, the statement<br />

fuelled it with many lambasting the way they<br />

thought the company had responded with an ad<br />

rather than any words of contrition.<br />

Statement number two was written by the<br />

boss, “Hello everyone, I am Pierre Wizman, I am<br />

French and the founder of polette.com. Our last<br />

communication was not an advertisement but<br />

an act of support in this crisis! I regret that our<br />

34 | NEW ZEALAND OPTICS JULY <strong>2020</strong>


STYLE NEWS<br />

message was wrongly interpreted, and I<br />

hope you will understand our intention<br />

was never about business but to share<br />

information...”<br />

Again, the statement was long. Again,<br />

Wizman attempted to explain why the<br />

company had run the promotion, “…It is<br />

purely an act of kindness from a country<br />

that is slowly getting out of the crisis.”<br />

But instead of apologising, he claimed<br />

the negative response was not deserved,<br />

“Polette is a brand that always puts a stress<br />

on solidarity and benevolence. All our<br />

actions express more than this message<br />

itself!” He continuing with how good<br />

the company has been and called on its<br />

followers “…to remain united… Polette is a strong and loving family and<br />

will continue to be! Love Pierre Wizman.”<br />

He might have ended the statement with ‘love’, but again all it did<br />

was compound the situation. The company was labelled “arrogant” for<br />

blaming its audience for not understanding what the company was<br />

trying to achieve and stating it was simply trying to do everyone a favour.<br />

This is a non-apology. The company said it was sorry, but then went on<br />

to say that it hadn’t actually done anything wrong and it wasn’t its fault<br />

it had been misunderstood. It even said its followers understood that –<br />

after it had deleted most of the really bad comments, leaving behind just<br />

the not-so negative ones in an attempt to rewrite social media history.<br />

My advice to Polette’s marketing team is to do a lot more research<br />

about different cultures before they launch their next promotional<br />

campaign and, if they muck up again, don’t issue a statement trying to<br />

justify what they did otherwise they will lose yet more of their current<br />

and future customers. Sometimes there is simply no way to rectify a<br />

marketing disaster, except to say, “Sorry. We messed up and we will learn<br />

from it. We can now see why this may be insensitive. Please forgive us.”<br />

How this relates to you<br />

Polette is a big company, so perhaps you’re thinking, what can an<br />

independent practice learn from this? The key for any business of any<br />

size when it comes to your marketing ideas is to know and understand<br />

your audience. If the area you practise in is family orientated for example,<br />

make sure you run events and promotions aimed at families, with plenty<br />

of eyewear suitable for the entire family. Be thoughtful about which topics<br />

might upset your audience, but also think about what might grab their<br />

attention. For families, children’s health is always at the heart of their<br />

parents’ interest and actions, so a good campaign idea might focus on<br />

simple tips to help protect their children’s eyes and eye health, for example.<br />

Many independent practice owners are often a little afraid to use social<br />

media to promote their businesses. Some may even choose not to have<br />

a social media presence to avoid the possibilities of backlash and dealing<br />

with angry or unreasonable customers. But don’t be afraid to reach out to<br />

customers and potential customers through social media and, if you do<br />

get it wrong, to apologise and show empathy. Consumers would much<br />

rather deal with a business that can demonstrate these traits and, if you<br />

handle the situation well, you can actually turn a negative situation into a<br />

positive one.*<br />

So, in summary, here’s a couple of ideas for building awareness for your<br />

business online:<br />

l Understand your local area – is it family, older people or business<br />

orientated, for example? And what sort of things do your audience enjoy/<br />

find interesting/important? Target social media interaction appropriately<br />

l Follow local groups to keep up to date with what’s happening and gain<br />

an even greater understanding of and involvement in your local area,<br />

offering your help and expertise when appropriate to reach more groups<br />

within your area<br />

l Consider timely promotions and information for your audiences. In the<br />

summer say, run a special sunglasses promotion; during winter, when<br />

people are more indoors, on their devices,<br />

discuss blue-light lenses for example<br />

Everyone wants to see instant results<br />

with marketing, but successful marketing<br />

is based on creating a lasting impression<br />

of your business among your target<br />

audience. All marketing should be viewed<br />

as a long-term investment, building<br />

subsequent promotions to gain a lasting,<br />

positive reputation. There is no point in<br />

having a great looking practice, top quality<br />

optometrists and dispensers, offering<br />

great products if you don’t tell people<br />

about it. But, most importantly, do your<br />

research to really understand your practice’s<br />

demographics, so whatever you do say,<br />

makes a good impression on those you’re wishing to reach and, if you do<br />

get it wrong, apologise!<br />

Decades of California style<br />

American surf brand O’Neill was founded in 1952 by Jack O’Neill in San<br />

Francisco and, nearly 70 years later, still embodies its original laidback,<br />

California style. O’Neill’s new optical range includes Kellsy, a glossy, crystal<br />

layered 100% plant-based and biodegradable acetate frame, available<br />

in bright teal, brown, black or purple. Kellsy’s stainless steel moulded<br />

temples and adjustable core-wire tips ensures a comfortable fit. Model<br />

Aidan offers a sheet stainless<br />

steel front and bespoke O’Neill<br />

acetate printed temples,<br />

available in four different colour<br />

combinations. O’Neill also offers<br />

a smaller fit for younger surfers.<br />

Street actor, footballer and<br />

witty presenter of UK ITV’s The<br />

Chase, now starring in Bradley<br />

Walsh & Son: Breaking Dad on<br />

TVNZ, suffers from blepharitis.<br />

It was during a Chase episode that<br />

viewers flocked to Twitter remarking<br />

on Walsh’s odd behaviour when<br />

he decided to speak out about<br />

his condition. Walsh developed<br />

blepharitis in his teens and told<br />

This Morning hosts that viewers<br />

often mistake him for being<br />

drunk because of his condition. “People don’t realise I have seriously<br />

bad blepharitis. I have to take one pill a day (anti-allergy medication)<br />

for it or I really struggle.” Walsh said he is pondering surgery as a<br />

solution to his problem. “I am going to need my eyes operated<br />

on at some point to sort it out. So many times, people have<br />

commented on how I look. But they don’t realise<br />

that if I take medication, I’m fine,” he said.<br />

Chalkeyes presents...<br />

Read all about it<br />

By David Slack<br />

IF YOU ARE reading this in its lustrous<br />

glossy printed form, you have in your hands<br />

a suddenly quite rare and precious thing: a<br />

magazine.<br />

Things are in turmoil in all kinds of ways<br />

and the media is not missing out on its share.<br />

That party was well underway before this<br />

pandemic.<br />

The worse it gets, the more it seems to<br />

echo farming in 1984: there was clearly a place<br />

for it; there was also clearly no way things<br />

could go on the way they were. Things were<br />

proceeding on the fond assumption the glory<br />

days of export dollars for slabs of frozen meat<br />

and bales of wool would return and all we had<br />

to do was wait and dish out subsidies. It was a<br />

delusion.<br />

Media has had a long, golden age, awash<br />

in advertising dollars. Now those dollars are<br />

being hoovered up by Facebook, Google and<br />

YouTube. Good luck ever getting them back.<br />

Moreover, in a world of free online media,<br />

how do you get people to pay?<br />

For farming, the moment of truth arrived<br />

in 1984 with Rogernomics. In came the free<br />

market, out went the subsidies; no more<br />

oxygen for the patient. For several years, it<br />

was awful carnage. Eventually farming found<br />

a new level; off it went again. Before long, the<br />

accepted wisdom was it had all been inevitable<br />

and the sector was the better for it.<br />

What will become the accepted wisdom<br />

for the media? Probably the prevailing order<br />

was no longer the right size or shape, that<br />

a sustainable future lies beyond the present<br />

arrangement of huge media organisations and<br />

expensive executives.<br />

What are the prospects for those of us who<br />

toil in this particular field, making lustrous<br />

publications, and what are the prospects for<br />

you, the reader, who might like to turn their<br />

lustrous pages?<br />

It doesn’t take all that much to tell a story.<br />

You need someone to begin with, “once upon a<br />

time”, and you need an audience that wants to<br />

hear what happened after that. That’s what the<br />

media is at its heart, perhaps with a preference<br />

sometimes for the story that involves<br />

something that someone, somewhere doesn’t<br />

want anyone to hear.<br />

In this digital world, it’s become possible<br />

to do that without much costly overhead. So,<br />

how about in place of the costly giants, we get<br />

an abundance of smaller operations, offering<br />

many different perspectives to many different,<br />

smaller audiences – crucially – connecting<br />

people sharing a common interest? They<br />

might live in the same neighbourhood, they<br />

might have a love for the same subject, they<br />

may follow a particular field, let’s say, oh,<br />

optometry and ophthalmology.<br />

The important thing is that whatever you<br />

do, whatever your interest, the media can<br />

enrich it, improve it, if it does its job well. The<br />

effect can be remarkable.<br />

For many years now I have had an<br />

association with a newspaper man in Mexico.<br />

His family had a small daily paper, a modest<br />

affair. He went off to study journalism in<br />

America, came home with a head full of ideas<br />

about freedom of the press in a country where<br />

there was none. This was 40 years ago. Back<br />

then, what got printed was determined by how<br />

much someone paid, or how much you were<br />

being threatened. He set about making a whole<br />

new kind of newspaper, one that printed the<br />

truth without fear or favour; no kickbacks, no<br />

censorship. They put it in the paper and put it<br />

on the streets. Every vested interest hated it.<br />

The people loved it.<br />

In the face of fierce and unending resistance<br />

and intimidation, he and his young idealistic<br />

team kept their nerve. They kept on reporting<br />

Credit: pxhere.com<br />

without fear or favour and each day more<br />

people bought a copy, and day by day, year<br />

upon year, that little newspaper grew. Today<br />

they print some of the country’s biggest daily<br />

newspapers and their influence, through<br />

exposing corruption, has been profound. They<br />

continue to succeed because their readers know<br />

they will be able to read in those newspapers<br />

what they cannot find anywhere else.<br />

In an age where you can read for free about<br />

Kardashians and trash, the publication that<br />

reports what no one else is reporting is the one<br />

you turn to. When the online world seems to<br />

be subverting democracy, publications that<br />

speak to our interests and values, that cares<br />

about our community of interest, about you,<br />

are something to prize.<br />

When the dust settles, I hope those will be<br />

the hearts still beating.<br />
