    Abstract:
    PURPOSE: To measure the proportion of people with major ophthalmic and retinal disorders in the tribal and non-tribal people presenting to a community eye hospital in an Indian state with a sizeable tribal population. METHODS: Hospital-based cross-sectional retrospective study of all new adult patients, examined between September 2015 and June 2020. A tribal was defined as per the Indian ethnic classification. Blindness and visual impairment were defined as per the WHO standards. Diabetes and hypertension were defined as per Indian standards. The proportion of common ophthalmic and retinal disorders between the tribal and non-tribal community were compared. RESULTS: This cohort consisted of 76,166 people (45.8%; n = 34,869, tribal); 39.4% (n = 29,989; non-tribal 23.6% and tribal 15.8%) people had ophthalmic disorders. In the examined people 2.3% were blind (higher in tribal community 4.7% versus 0.8%; P < 0.001) and 8.4% had moderate-to-severe visual impairment (higher in tribal community 14.4% versus 4.4%; P < 0.001). Refractive error (64.4%; higher in non-tribal community, 77.3% versus 44.6%, P < 0.001) and operable cataract (23.9%; higher in tribal community, 40.9% versus 11.8%, P < 0.001) were the principal ophthalmic disorders. Retinal disorders were higher in non-tribal people (5.9% vs. 2.9%; P < 0.001), but the tribal group had higher proportion of retinitis pigmentosa (20% vs. 6.4%; P < 0.001) and lower proportion of diabetic retinopathy (8% vs. 40.7%; P < 0.001). CONCLUSION: : The health-seeking behavior of the tribal community in India is low. A tribal person in India apparently visits the hospital when vision is grossly affected. It calls for greater advocacy, increased access to healthcare, and a larger population-based study.
