Ocular morbidity pattern and its risk factors: A study among rural population of West Bengal

Background:Visual impairment resulting from infectious diseases has declined by public health efforts but cataract and refractive errors still continue as major causes of blindness. Moreover, ageing & life style diseases also contribute to large number of blindness. Objective: This study was undertaken to assess the ocular morbidity pattern and the risk factors among rural population of West Bengal. Material & Methods: A community based, descriptive, observational study was conducted in Hariharpur PHC. One subcentre was chosen purposively and three villages under the subcentre were chosen randomly. The study population comprised of all persons residing in those villages for at least one year. Door to door visit was conducted for screening of eye problems and then detailed examination was carried out in the PHC by ophthalmic assistant. Subjects requiring specialist consultation were referred. Results: Difficulty with vision was the commonest complain followed by watering, burning and itching sensation, pain and redness. Refractive errors (myopia & hypermetropia) were the commonest morbidity among all age groups followed by cataract and allergic conjunctivitis. Cataract was found to be significantly associated with diabetes and hypertension (P=0.001) and allergic conjunctivitis was associated significantly with hypertension (P=0.007). Interestingly quite a high proportion of the patients with visual complaints could be detected and managed at the PHC level . So simple screening for eye disorders and utilization of trained ophthalmic assistants can enable early detection of eye conditions, prompt treatment and early referral.
