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.

以人群为基础的评估患病率，原因，单侧视力障碍的危险因素在泰伦加纳邦，印度老年人。

目的：报告印度特伦加纳邦老年人（≥60岁）单侧视力障碍（UVI）的患病率、原因和危险因素。方法：在特伦加纳邦的四个地区进行了一项以人群为基础的横断面研究。训练有素的小组进行眼科检查。距离视力（VA）在6 m处采用滑动E型Snellen视力表评估。对所有参与者进行前眼检查和无散瞳眼底成像。UVI被定义为一只眼睛的VA低于6/18，而另一只眼睛的VA高于或等于6/18。进行多变量分析以评估与紫外线相关的因素。结果：在2447名年龄≥60岁的参与者中，1285名（52.5%）为女性，1786名（73%）未接受过正规教育。总共有525人（21.5%）来自阿迪拉巴德，602人（24.6%）来自马赫布纳加尔，610人（24.9%）来自哈曼，710人（29%）来自瓦朗加尔。参与者的平均（标准差）年龄为66.6（±6.3）岁。UVI患病率为34.9% (95% CI: 33.0-36.9；n = 856)。白内障(48.5%;n = 415)是导致UVI的主要原因，其次是未矫正屈光不正(33.1%；n = 284)。多变量分析显示，老年群体以及居住在Khammam和Warangal地区的人患紫外线辐射的几率更高。结论：特伦加纳邦超过三分之一的老年人患有紫外线损伤。10个紫外线病例中有8个可以通过在初级和二级眼科护理中分别提供眼镜和白内障手术来解决。

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.
