Abstract

Purpose: To report the prevalence, causes, and risk factors for unilateral visual impairment (UVI) among the elderly population (≥60 years) in Telangana, India.

Methods: A population-based, cross-sectional study was conducted in four districts of Telangana. Trained teams conducted eye examinations. Distance visual acuity (VA) was assessed using a Snellen chart with a tumbling E optotypes at 6 m. Anterior eye examination and non-mydriatic fundus imaging were performed for all participants. UVI was defined as presenting VA worse than 6/18 in one eye and VA better than or equal to 6/18 in the other eye. Multivariable analysis was performed to assess the factors associated with UVI.

Results: Of 2,447 participants aged ≥60 years were included in the analysis, 1,285 (52.5%) were women, and 1,786 (73%) had no formal education. In total, 525 (21.5%) participants were from Adilabad, 602 (24.6%) from Mahbubnagar, 610 (24.9%) from Khammam, and 710 (29%) from Warangal districts. The mean (standard deviation) age of the participants was 66.6 (±6.3) years. The prevalence of UVI was 34.9% (95% CI: 33.0-36.9; n = 856). Cataract (48.5%; n = 415) was the leading cause of UVI, followed by uncorrected refractive error (33.1%; n = 284). The multivariate analysis showed higher odds of UVI in the older age group and among those residing in the Khammam and Warangal districts.

Conclusion: Over a third of the elderly population in Telangana had UVI. Eight out of 10 cases of UVI could be addressed by providing spectacles and cataract surgery at primary and secondary levels of eye care, respectively.

期刊介绍： Ophthalmic Epidemiology is dedicated to the publication of original research into eye and vision health in the fields of epidemiology, public health and the prevention of blindness. Ophthalmic Epidemiology publishes editorials, original research reports, systematic reviews and meta-analysis articles, brief communications and letters to the editor on all subjects related to ophthalmic epidemiology. A broad range of topics is suitable, such as: evaluating the risk of ocular diseases, general and specific study designs, screening program implementation and evaluation, eye health care access, delivery and outcomes, therapeutic efficacy or effectiveness, disease prognosis and quality of life, cost-benefit analysis, biostatistical theory and risk factor analysis. We are looking to expand our engagement with reports of international interest, including those regarding problems affecting developing countries, although reports from all over the world potentially are suitable. Clinical case reports, small case series (not enough for a cohort analysis) articles and animal research reports are not appropriate for this journal.
