The aim of this study was to determine habitual visual acuity (HVA) in a large urban cohort in western India and identify factors associated with poor HVA.
This was a prospective study conducted over 10 days in September 2018 to assess the HVA in individuals attending a 10-day festival in Western India. Participants who volunteered to undergo vision screening and also filled the questionnaire form pertaining to demographic information including their age, gender, address, income, and educational status were included in this study. HVA was recorded with the distance correction that the participants were wearing when they attended the screening. The study evaluated the prevalence of visual acuity 6/6 or <6/6, 6/12, and 6/18 and the factors associated with lower visual acuity.
Of the 6300 participants, 1660 (26.3%) were females. Majority of the participants were from urban background (6084, 96.6%) and were of younger age group (18-40 years--3786, 60.1%; 41-60 years--2187, 34.7%; >60 years--327, 5.2%). HVA was recorded as 6/6 both eyes in 4136 (65.6%), at least 6/12 both eyes in 5691 (90.3%), and at least 6/18 both eyes in 5974 (94.8%) individuals. Only 11 patients (0.17%) had VA worse than 6/60 with only 3 patients (0.003%) having bilateral VA <6/60. Older age, female sex, lower education status, and low annual income were significant risk factors for poor HVA.
Poor education, lower income, female gender, and old age are significantly associated with poor HVA even in urban Western India despite relatively easy access to affordable eye care facilities.
本研究旨在确定印度西部一个大城市队列的习惯性视力（HVA），并确定与 HVA 差相关的因素。
这是一项在 2018 年 9 月进行的为期 10 天的前瞻性研究，旨在评估参加印度西部 10 天节日的个体的 HVA。参加视力筛查并填写有关人口统计学信息的问卷表的志愿者，包括年龄、性别、地址、收入和教育程度，包括在本研究中。HVA 是用参与者参加筛查时所戴的距离矫正来记录的。本研究评估了视力 6/6 或<6/6、6/12 和 6/18 的患病率以及与较低视力相关的因素。
在 6300 名参与者中，有 1660 名（26.3%）为女性。大多数参与者来自城市背景（6084 人，96.6%），年龄较小（18-40 岁 3786 人，60.1%；41-60 岁 2187 人，34.7%；>60 岁 327 人，5.2%）。双眼 HVA 记录为 6/6 的有 4136 人（65.6%），双眼至少为 6/12 的有 5691 人（90.3%），双眼至少为 6/18 的有 5974 人（94.8%）。只有 11 名患者（0.17%）的视力低于 6/60，只有 3 名患者（0.003%）的双眼视力<6/60。年龄较大、女性、较低的教育程度和较低的年收入是 HVA 差的显著危险因素。
即使在印度西部的城市，较差的教育、较低的收入、女性性别和年龄较大与较差的 HVA 显著相关，尽管获得负担得起的眼保健设施相对容易。
