Purpose: To assess associations between age-related macular degeneration
(AMD) and ocular and general parameters.
Methods: The Central India Eye and Medical Study included 4711 subjects.
Fundus photographs were assessed using the Wisconsin Age-Related
Maculopathy Grading system.
Results: Early AMD was present in 215/4542 subjects (4.7 ± 0.3%), and late
AMD was detected in 8/4542 (0.2 ± 0.03%) subjects. After adjustment for age,
prevalence of AMD was associated with hyperopic refractive error (P=0.001),
shorter axial length (P=0.01), and higher corneal refractive power (P=0.02).
Each diopter increase in hyperopic refraction or each mm decrease in axial
length was associated with an 15% (odds ratio (OR):1.15; 95% confidence
interval (CI):1.06, 1.24) and 19% (OR:0.81; 95% CI:0.69, 0.95) increased
probability of early AMD, respectively. AMD was not significantly associated
with blood pressure, serum concentration of cholesterol, glycosylated
haemoglobin Hb1Ac, high-density lipoproteins and postprandial glucose,
gender, level of education, any parameter of smoking, alcohol consumption,
psychiatric depression or of daily activities, anterior chamber depth, lens
thickness, intraocular pressure, size of the optic disc, neuroretinal rim and
parapapillary atrophy, nor amount of nuclear cataract and status after cataract
surgery.
Conclusions: Hyperopia (and short axial length) besides age was the single
most important associated factor for AMD in adult Indians.

Aim: To evaluate the presence of vision impairment in combination with other
disabilities and to assess the need for extra assistance in accessing the
educational curriculum.
Methods: As part of a needs analysis in determining the prevalence of vision
impaired children aged 0 to 18 years in 2006, vision screening was conducted
at the 7 special schools in the Central Medical Division, Fiji. Students from
the Fiji School for the Blind were not included as they were already getting
maximum support in accessing the educational curriculum. Results: A total of
201 students aged 0 to 18 years were screened. 79% had normal vision and
39% were identified as having some vision impairment that needed referral to
either the optometrist or ophthalmologist. Of those who were referred, 26%
had low vision while 51% had uncorrected refractive error. All students with low
vision were referred to the low vision clinic and hence to the Fiji Society for the
Blind for extra support and assistance as required.
Conclusion: Vision impairment is common in children with disabilities; these
results underline the importance of screening vision in special schools to
ensure that the children receive correction or treatment of vision loss and
appropriate educational support.

Purpose: The blind school data published in 2006 from Western India region of
India Retinopathy of prematurity (ROP) as a cause of blindness is not
mentioned. We are involved in ROP screening activities and we see lot of
children with blindness due to ROP in our clinics. So a study was planned to
assess the recent pattern of childhood blindness in schools for the blind in
Pune region with special emphasis on ROP as a cause of blindness in these
children.
Methods: We collected data from schools for the blind in 2010 at Pune to know
the recent trends in childhood blindness by examining children with visual
impairment using WHO/PBL eye examination record for children with blindness
and low vision.
Results: Out of 243 children examined in blind schools 12 (4.9 %) had ROP
blindness. This is much higher than the previously reported figures from same
area.
Conclusions: Considering this data there is an urgent need to intensify the
ROP screening program and train more people in detection and treatment
of Retinopathy of prematurity. Also a monitoring mechanism should be
established for neonatal intensive care units to prevent occurrence of ROP.

Objective: Incidence and causes of blindness among Kuwaiti citizens evaluated
by the Visual Disability Committee from January 2005 to December 2009.
Methods: Age-specific rates per 100 000 person years of observation in 4 age
groups and age - standardized incidence rates per 100 000person years of
observation for the total population in 4 severity groups according to ICD - 10
Edition.
Results: Total age-standardized incidence rate was 31.88 for the males and
18.59 for the females, the majority with BCVA light perception to finger
counting at 1 m, males twice more in all categories except the group with no
light perception. Age-specific incidence rates doubled for the age 41-60 (37.12
for the males and 21.88 for females) and tripled for those over 61 (77.30 for
the males and 57.51 for the females). Retinitis pigmentosa was leading cause
for those below 40, followed by optic atrophy and congenital anomalies. Endstage
diabetic complications and glaucoma were major causes for patients
over 41.
Conclusions: Hereditary disorders prevail in younger age due to wide-spread
consanguinity marriages, while more effective screening and treatment of
diabetic eye complications and glaucoma will be needed for those over 40.
