Abstract
Purpose: To determine the causes of severe visual impairment and blindness in children in schools for the blind in Maharashtra, India. Methods: Children aged <16 years, enrolled in the schools for the blind in Maharashtra state, India were examined between October 2018 and December 2019. The anatomical sites and etiology for blindness were recorded using the World Health Organization’s standard reporting form. Causes of blindness were compared among different regions of the state and also by different age groups. Results: Of the 1,969 students examined from 39 schools for the blind, 188 children (9.5%) had severe visual impairment and 1,666 children (84.6%) were blind. Whole globe anomalies (794, 42.8%) were the most common anatomical site of vision loss in children, followed by corneal (289, 15.6%) and retinal abnormalities (280, 15.2%). Corneal causes were second most common in the poorer districts of Vidarbha (15.3%) and Marathwada (14.6%), whereas retinal causes were second most common in the wealthier regions of western Maharashtra (18.3%) and Khandesh (24.1%). Nearly one?third (593, 32%) of children were blind from potentially avoidable causes. Preventable blindness consisting of corneal causes and retinopathy of prematurity was seen in 281 (15.2%) cases, whereas treatable causes comprising of lens?related causes, glaucomas, refractive errors, amblyopia, and uveitis accounted for another 311 (16.8%). Among the younger children (?10 years), the proportion of corneal blindness was lower (83/623, 13.3% vs. 206/1232, 16.7%) and that of retinal blindness was higher (119/623, 19% vs. 163/1232, 13.2%) than the older children. Conclusion: Whole globe anomalies constitute a major cause of SVI and blindness in Maharashtra. There seems to be an increase in the proportion of retinal blindness, especially retinopathy of prematurity, suggesting a need for increased screening coverage
