To evaluate Glaucomatous Optic Neuropathy (GON) and blindness in narrow angle glaucoma patients. MATERIALS AND METHODS: This is a hospital based retrospective analysis primary angle closure glaucoma patients attending eye OPD between June 2013 to May 2014.The demographic data related to age, sex, IOP and type of glaucoma was analyzed. Primary angle closure glaucoma (PACG) was diagnosed and categorized into symptomatic and asymptomatic groups according to the history and clinical presentation. Disc damage likelihood scale (DDLS) was used to evaluate glaucomatous optic neuropathy. RESULTS AND CONCLUSION: Out of 96 cases of all primary glaucoma cases, narrow angle glaucoma was present in 54 patients. Out of 54 cases, 36(67%) were asymptomatic and 18(33%) were symptomatic. Moderate to severe glaucomatous optic neuropathy was found in 64% in asymptomatic group. There were 45% cases with unilateral blindness in asymptomatic group as compared to 19% in symptomatic narrow angle glaucoma group. CONCLUSION: Asymptomatic narrow angle glaucoma was more commonly found. Increasing age, female gender and high IOP were significantly associated with it. Blindness due to asymptomatic narrow angle glaucoma was double as compared to acutely presenting narrow angle glaucoma.
