“…16,17 The Beijing study (2008) estimated the blindness prevalence at age 3-6 was 0.3/1,000 16 and the national survey of 0-6 year old children in 2004 produced a prevalence estimate of blindness in this age group of 0.3/1000. 17 In contrast, the prevalence was lower than estimates from other Asian settings, such as India, 8,18 and Bangladesh. 12 The prevalence estimate from this KIM study is a minimum estimate for the following reasons.…”

“…The major causes of childhood blindness vary from place to place. 5,[8][9][10][11] In low income countries, corneal scarring from measles, vitamin A deficiency (VAD), ophthalmia neonatorum, and harmful traditional medical practice predominate as the leading causes. Cataract, congenital abnormalities and hereditary retinal dystrophies are important in all areas.…”

Childhood cataract is an avoidable cause of visual disability worldwide and is a priority for VISION 2020: The Right to Sight. There is a paucity of information about the burden of cataract in children and the aim of this review is to assess the global prevalence of childhood cataract. The methodology for the review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We performed a literature search for studies reporting estimates of prevalence or incidence of cataract among children (agedo18 years) at any global location using the Cochrane Library, Medline and Embase up to January 2015. No restrictions were imposed based on language or year of publication. Study quality was assessed using a critical appraisal tool designed for systematic reviews of prevalence. Twenty prevalence and four incidence studies of childhood cataract from five different geographical regions were included. The overall prevalence of childhood cataract and congenital cataract was in the range from 0.32 to 22.9/10000 children (median = 1.03) and 0.63 to 9.74/10000 (median = 1.71), respectively. The incidence ranged from 1.8 to 3.6/10000 per year. The prevalence of childhood cataract in low-income economies was found to be 0.42 to 2.05 compared with 0.63 to 13.6/10000 in high-income economies. There was no difference in the prevalence based on laterality or gender. This review highlights substantial gaps in the epidemiological knowledge of childhood cataract worldwide, particularly from low and lower middle-income economies. More studies are needed using standard definitions and case ascertainment methods with large enough sample sizes.

“…9-12 Two population-based studies from India have reported a much higher proportion of blindness in female children compared to males, 13,14 which suggests that the preponderance of males in schools for the blind is likely to reflect social bias toward education of males rather than gender differences in causes of blindness. 4 Of the 95 children in this study, over 65% were BL/SVI, with the lens being the most common major site of abnormality (27.4%) and the majority of these being cataracts (24.2%).…”

Childhood Blindness in a Rural Population of Southern India: Prevalence and Etiology

Abstract: More than half of the blindness detected was potentially avoidable. Genetic counseling, early identification and access to tertiary care would reduce the burden of childhood blindness in the local community.
