评估印度南部安得拉邦≥40岁的城市和农村人群中视力损害的患病率和原因。一项基于人口的横断面研究，其中7800名受试者从两个农村和城市的位置进行抽样。使用翻滚E视力表评估视力（VA），并由经过培训的视力技术人员进行眼部检查。调查问卷用于收集个人和人口统计学信息以及之前向眼科护理提供者咨询的信息。视力较好眼视力<6/60为盲，视力较好眼视力<6/18 ~ 6/60为中度视力损害（VI）。VI包括盲和中度VI。在7800名受试者中，7378名（94.6%）接受了检查。在接受检查的人中，46.4%是男性，61.8%没有受过教育。受检者的平均年龄（51.7岁;标准差10.9岁）与未受检者（52.8岁;标准差9.9岁）相似（p = 0.048）。 年龄和性别校正的VI患病率为14.3%（95% CI：13.5-15.0）。屈光不正是视力下降的主要原因，占视力下降的47.6%，其次是白内障（43.7%）。两者合计，占VI总额的91.3%以上。多元逻辑回归分析显示，随着年龄的增长，VI的几率显著增加。那些没有受过教育的受访者是两倍（95% CI：1.7-2.5）更有可能有VI相比，那些受过教育的。VI与农村居住相关（OR：1.3; 95%CI：1.1-1.6）。VI和性别之间的关联没有统计学意义。视力障碍仍然是安得拉邦的一个公共卫生挑战，其中大部分可以通过白内障手术和眼镜等相对直接的干预措施来解决。眼科护理服务需要简化，以应对这一挑战。
To assess the prevalence and causes of visual impairment in urban and rural population aged ≥40 years in the South India state of Andhra Pradesh. A population based cross-sectional study was conducted in which 7800 subjects were sampled from two rural and an urban locations. Visual Acuity (VA) was assessed using a tumbling E chart and eye examinations were performed by trained vision technicians. A questionnaire was used to collect personal and demographic information and previous consultation to eye care providers. Blindness and moderate Visual Impairment (VI) was defined as presenting VA <6/60 and <6/18 to 6/60 in the better eye respectively. VI included blindness and moderate VI. Of the 7800 subjects enumerated, 7378 (94.6%) were examined. Among those examined, 46.4% were male and 61.8% of them had no education. The mean age of those examined (51.7 years; standard deviation 10.9 years) was similar to those not examined (52.8 years; standard deviation 9.9 years) (p = 0.048). Age and gender adjusted prevalence of VI was 14.3% (95% CI: 13.5–15.0). Refractive errors were the leading cause of VI accounting for 47.6% of all VI followed by cataract (43.7%). Together, they contributed to over 91.3% of the total VI. With multiple logistic regression, the odds of having VI increased significantly with increasing age. Those respondents who had no education were twice (95% CI: 1.7–2.5) more likely to have VI compared to those who were educated. VI was associated with rural residence (OR: 1.3; 95% CI: 1.1–1.6). The association between VI and gender was not statistically significant. The visual impairment remains a public health challenge in Andhra Pradesh, most of which can be addressed with relatively straight forward interventions like cataract surgery and spectacles. The eye care services need to be streamlined to address this challenge.
