Tribal Odisha Eye Disease Study (TOES). Report # 10. Disability inclusive eye health survey in a tribal district (Rayagada) in Odisha, India

Purpose: To estimate seeing and other disabilities in a population cohort in a tribal district, Rayagada, in the Indian state of Orissa. Methods: A door-to-door survey was conducted to identify the disabilities. The vision was measured at the residence of the subject, and other disabilities were documented from the history obtained from the subject/household/neighbor. All people with seeing disabilities were reexamined in the community eye center (primary or secondary), and required treatment was given at no cost to the patients. People with other disabilities were transported to the public health facility for appropriate care and disability certification. The results were compared with the 2011 national census data. Results: A total of 147,699 people were enumerated, and 106,339 (72%) were examined over one year period, 2016-17. In this cohort, 47.3% (n = 50,320) were male and 27.5% (n = 29,215) were 40 years or older. We recorded systemic disease in 0.6% (n = 689) people; hypertension was two times higher than diabetes mellitus. Disability was identified in 2.8% (n = 3022). Common disabilities were seeing (46.7%; n = 1411), hearing (36.8%; n = 1112), mobility (10.4%; n = 315), and mental retardation (3.2%; n = 98). Dual sensory disability (seeing and hearing) was seen in 6.4% (n = 251), and it was higher in the older age group. Seeing and hearing disabilities were higher than the 2011 state (P =< 0.001) and national (P =< 0.001) disability census. Conclusion: The first population-based survey in Rayagada, Odisha (India) in 2017 showed a higher proportion of people with seeing and hearing disabilities. It calls for an appropriate service strategy.
