Tribal Odisha Eye Disease Study (TOES) Report # 9. Eye diseases and retinal disorders in an adult and elderly tribal community in Odisha, India - A community hospital-based study

Purpose: The World Report on Vision highlights that health information systems (HIS) should collect information on the determinants of eye conditions and vision impairment (VI) as a step toward integrated people-centered eye care (IPEC). Thus, this retrospective study aims to elucidate VI trends across age and gender of the patients who visited our centres in southern and eastern India. Methods: Electronic medical records of all new patients who visited the network were included. VI was defined as visual acuity less than 6/12; unilateral VI was based on the worse presenting eye (the other eye being normal), and bilateral VI was based on the better eye. “Total VI” includes both unilateral and bilateral VI. Results: The records of 7,31,307 patients from January to December 2019 were extracted. Males were 54%. The mean age was 40 years (SD: 19.16 years). The majority of patients (46.54%) visited a primary care centre. Centres in Andhra Pradesh saw the largest number of patients (46%). Approximately 65% of all patients presented had no VI in either eye. Total VI was 23.5% at the primary-centre level and approximately 45% at other levels, the highest being in Odisha. More females accessed care at primary and secondary centres (46.6%) than at higher levels of care (44%). Odisha had the lowest number of females accessing care (43.01%). Conclusion: Non-visually impairing conditions form an important reason for patients visiting our eye care facilities. Strategies focusing on improving access to eye care for females should be planned at all levels, especially in Odisha.

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.

Purpose: To describe and validate the eye health program protocol of Dongria tribal community, a particularly vulnerable tribal group (PVTG) in Rayagada district, Odisha, India. Methods: The program would consist of three segments. At people’s residences, trained community health workers (CHWs) will measure the vision and collect demographic data. In addition, vision technicians (VTs) will refract using a hand-held device and prescribe spectacles to people who improve to >6/12, N8. Others would be referred to the vision center (VC). At VC, the VT will perform a slit-lamp examination and re-refract. They would refer people with vision ≤6/12 to the secondary center (SC). At SC, referred people will receive a comprehensive eye examination and treatment. The ophthalmologist will assign the cause of blindness and visual impairment for people with visual acuity <6/12. The entire process was rehearsed in a pilot study. Results: The target population is approximately 10,000 people residing in 101 hutments on the hills of Rayagada district. The pilot study included 126 people. The mean age was 44 ± 18 years; 70% of the people were illiterate, and in this cohort, 97.6% (n = 123) had never worn spectacles. In the pilot study, 41% of the people had cataract, and 12% had pterygium. The agreements between optometrist versus VTs and between optometrist versus CHWs were good (k = ~0.8–1.0) in all eye conditions except for strabismus (k = ~0.56–0.65) Conclusion: The pilot study confirms the program modality, and when completed, it would help in the planning and resource allocation of Odisha PVTG eye care.
