The Future of Imaging in Glaucoma
Schmetterer Leopold
Imaging of the optic nerve head has become a standard tool in glaucoma
management. Optical coherence tomography (OCT) may be superior to other
methods due to its unprecedented reproducibility and sensitivity. It is, however,
not clear yet whether OCT has the potential to fully replace older imaging
technologies in glaucoma diagnosis. The present talk gives an overview
of the current status and also introduces some approaches to extend OCT
technology towards assessment of functional parameters.

The Value of Imaging in Clinical Praxis
Hommer Anton (1)

The exact documentation of appearance and changes in optic nerve head and
retinal nerve fiber layer is essential in our daily management of glaucoma and
ocular hypertensive patients. Detailed manual drawing is the minimum for
documentation. Digital Colour photography provides objective documentation,
but quantitative imaging is only possible with computer assisted devices
like GDx, HRT or OCT. Especially for follow up it is very difficult to quantify
progression in fundus photography. The quantitative data for assessing
progression like in HRT, GDx and OCT is providing important information to
offer best follow up for structure analysis. The modern 3-dimensional imaging
techniques are very promising to detect early changes but we always should
remember that our clinical management should be in context with other
important clinical data to evaluate correctly the relevance for the individual
patient.

Purpose: To evaluate the risks and benefits of simultaneous bilateral surgery in
congenital cataract .
Methods: We retrospectively evaluated the postoperative course of 64 eyes of
32 children who underwent bilateral cataract surgery in single sitting. There
were 20 cases of congenital rubella syndrome, 8 with heart diseases, 2
galactosemia, 2 very low birth weight and one case each with homocystinuria
and hemophilia. Age of the patients ranged from 2 months to 7 years with most
being under 2 years of age.
Results: No major intraoperative complication was noted. On postoperative
follow up for 6 months, none of the cases developed endophthalmitis. One
case developed traumatic hyphaema at 2nd postoperative week. Two cases
developed grade 4 uveitis in both eyes which was relieved with topical steroid
medication.
Conclusion: Simultaneous bilateral congenital cataract surgery is a useful
option for cases with high systemic risk profile like associated heart diseases
as to avoid a second general anesthesia. It also reduces the risk of amblyopia.
In selected cases of bilateral cataracts, the benefits of cataract surgery in
single sitting outweighs, the potential risks and should be considered the
primary option.

Purpose: To determine the safety, refractive outcome and the prediction error
in surgically aphakic children undergoing secondary intraocular lens
implantation (IOL).
Methods: Retrospective, interventional case series of children who underwent
secondary IOL implantation, post congenital cataract surgery, between January
2000 and December 2010. Study parameters included patient demography,
best corrected visual acuity (BCVA) at presentation and final follow up, target
refraction, complications and prediction error at 3 months.
Results: 174 eyes of 104 children (M/F=68/36) were included in the study.
Mean duration, for secondary IOL implantation was 6.08± 3.75 years for males
and 5.6±2.8 years for females, after primary cataract surgery. Mean follow-up
was 25.70+ 24.99 months (3 to 127 months; median-18 months). BCVA was
≥20/80 in 31.03% of children. Target refraction was age appropriate.
The mean prediction error at 3 months was 1.65+2.46 diopters (3.25 D to 11D).
Mean spherical equivalent at 3 months was -0.009D+ 2.43D (range -7 D to
6D). Complications included wound leak (2), hyphema (2), glaucoma (11), and
optic capture (15).
Conclusion: Secondary IOL implantation is a relatively safe procedure in
children. Though age based refraction is targeted, there is a possibility of
prediction error and refractive surprises.

Objective: To analyze mode of presentation and effect of prognostic variables
on clinical outcome following surgical management of traumatic cataract
amongst children.
Methods: Retrospective review of 77 eyes with traumatic cataract in patients
younger than 17 years who underwent surgical intervention at our institute
from March 2005 to December 2010. Results: Open globe injuries accounted
for 69% of cases. 59.7% of the trauma occurred in rural setting. Commonest
cause of trauma was wooden sticks and arrows in both rural (32.6%) and urban
(32.2%) settings. Visual acuity improved from < 20/200 in 91.7% of patients
preoperatively to ? 20/80 in 72.6% of patients postoperatively (P=0.0001).
Involvement of retina (36%) was the major factor leading to decreased
postoperative vision. Improvement in visual acuity was not significantly
associated with type of trauma (P=0.86), timing of surgery (P=0.69), lens
implantation (P=0.33) or type of lens implanted (P=0.95). Visual axis
opacification (VAO) occurred in 12.9% cases, 20% of which needed surgical
intervention. While VAO was significantly associated with intact posterior
capsule (P=0.01), it was not statistically associated with lens implantation
(P=0.11) or type of lens implanted (P=0.61).
Conclusion: Primary management of posterior capsule should be attempted in
all cases for better visual outcome.
