Abstract
PURPOSE To determine the severity and various causes of visual impairment in patients seeking visual disability certificate. METHODS Cross-sectional study of patients seeking visual disability certificate from November 2014 to April 2015 was done. Severity of visual impairment was calculated as per the guidelines of Ministry of Social Justice and Empowerment 1999. Cause was ascertained after detailed examination which included slit-lamp examination, direct ophthalmoscopy, indirect ophthalmoscopy, slit-lamp biomicroscopy with 78D lens, Humphrey visual field analysis wherever necessary. RESULTS Of the 267 patients, category 0-7 (2.62%), category 1-37 (13.85%), category 2-42 (15.73%), category 3-157(58.80%), one eyed- 24 (8.98%). Male preponderance was seen (56.55%). The causes were congenital malformations-78 (29.21%), retinitis pigmentosa- 71 (26.59%), refractive errors with amblyopia-52 (19.47%), corneal opacity related to trauma and infectious keratitis 22(8.23%), glaucoma-14 (5.24%), phthisis bulbi-9 (3.37%), ARMD-3 (1.12%), miscellaneous-9 (3.37%). The causes were preventable in 41.19%. CONCLUSION Most of the patients who sought disability certificate were totally blind. The leading causes for visual impairment were congenital malformations, retinitis pigmentosa and refractive errors with amblyopia. 41.19% patients suffered from visual impairment caused by potentially preventable conditions. The burden of visual impairment can be reduced by taking necessary preventive measures with the leading causes being identified.
