Vision Delhi: A study of primary eye care model operational in urban slums and resettlement colonies of Delhi.

Abstract

Background:Family physicians (FPs) encounter numerous patients who need eye care services. For providing eye care services at the primary level, they need to be abreast with the common disorders, their management and appropriate referral.Objectives:The aim of this study was to describe the socio-demographic and ocular morbidity profile of the beneficiaries, seasonal pattern of few ocular disorders and to find the proportion of blindness that is avoidable at the primary level.Methodology:Study was conducted in 25 vision centers across Delhi. Chart review was done in each center and retrospective data of previous 4 years was analyzed. Socio-demographic, ocular morbidity profile and trend of selected diseases was deducted and causes of blindness were determined.Results:Around 62.76% of patients were women and 78.26% were new patients. A seasonal peak of conjunctivitis was observed during the spring season. The common conditions detected by optometrists were refractive errors (34.68%), presbyopia (14.15%), cataract (14.02%), conjunctivitis (9.84%) and diseases of ocular adnexa (1.35%). In the age group ≥50 years, the proportion of patients who were blind was 2.5%, 39.0% had VI. The proportion of VI patients in all the categories was higher in women as compared to men. In patients ages ≥50 years, 81.4% of the blindness was avoidable.Conclusions:Women outnumbered men in availing services at the center and the proportion of visual impairment was also higher in them. The major causes of blindness in the older population were cataract and corneal-opacity, and it is avoidable by strengthening primary eye care services by FPs.
