Purpose: To determine the etiological spectrum of irreversible blindness in Kashmir Valley in India. Methods: Patients presenting to a tertiary care hospital in Kashmir, India, with unilateral or bilateral blindness from April 2019 to March 2020 were included in this cross-sectional study. Blindness was defined using the World Health Organization (WHO) criteria. All subjects had a complete ophthalmologic examination and information was gathered regarding their demographic profile, nature of ocular disorder whether primary or secondary and laterality, if the ocular involvement was unilateral. Results: 248 patients were enrolled in the study. The mean age of the patients was 57.17 years. The male: female ratio was 2.17:1. The commonest cause of unilateral or bilateral blindness was glaucoma (22.58%) followed by diabetic retinopathy (DR) (17.74%). Unilateral blindness was seen in 78.62% of the patients. Unilateral blindness occurred mainly due to glaucoma (16.41%), DR (14.87%), age-related macular degeneration (13.33%), and trauma (pellet injury: 10.76%, non-pellet injury: 10.25%). The major causes of bilateral blindness were glaucoma (45.28%), DR (28.30%), and hereditary/congenital retinal diseases (16.98%). Socioeconomic status and educational status were significantly associated (P 0.05 each) with the number of eyes affected by blindness. Conclusion: Glaucoma and DR are the foremost causes of irreversible blindness in Kashmir. Public health plans aimed at encouraging good health education of patients should be developed in this region. Moreover, patients should be screened effectively for glaucoma and diabetes at the level of primary health care facilities.
