Vision improvement with low vision aids and functional vision assessment among children studying in schools for the blind in North-East India

Abstract

Background: The study aimed to assess the vision improvement with low vision aids (LVA) and functional vision among children learning in schools for the blind in North-East India. Material and methods: 515 students from 17 blind schools of North-East India were recruited. The comprehensive ocular examination, functional vision assessment, and vision assessment using LVA were carried out for all the subjects after determining the magnification required for each subject. Results: Of 515 children, 124 required LVA. Spectacle magnifiers were the most preferred (73 students, 58.87%), followed by magnifiers (50 students, 40.32%). A statistically significant improvement in the mean visual acuity was noted after the use of LVA (p < 0.001). Conclusion: A detailed assessment of low vision prior to admission to schools should be made mandatory in blind schools. These schools would be able to cater to really blind children, while children with low vision could attend regular schools.
