背景和证据：在沙特阿拉伯进行的研究很少，以估计视力障碍的患病率及其原因。本研究的目的是估计视力损害的患病率，并确定其原因和相关因素之间的成年人口参加初级卫生保健（PHC）中心在Aljouf省，在北方沙特阿拉伯。设计和设置：一个横断面研究，在2005年在PHC中心在Aljouf省在北方沙特阿拉伯患者和方法：通过多阶段随机抽样技术，从Aljouf PHC中心的集水区随机抽取了620名18岁及以上的沙特成年人。使用社会经济和相关信息的问卷收集数据，并使用Snellen视力表（E）进行视力测试。根据世界卫生组织（WHO）标准确定诊断。视力损害分类为失明（最佳矫正视力低于3/60（20/400，0.05））和低视力（最佳矫正视力低于6/18（20/60，0.3）但不低于3/60（20/400，0.05））。回归分析被用来确定预测视力impairment.RESULTS：617成年沙特人采访和检查，269（43.6%）是女性。平均（SD）年龄为38.6（16.2）岁。视力损害的总体患病率为13.9%（95%CI：11.4%-16.9%）。视力损害的主要原因是屈光不正（36.0%），其次是白内障（29.1%）和糖尿病视网膜病变（20.9%），最少的原因是青光眼（5.8%）。视力损害的最显著决定因素是年龄（P
BACKGROUND AND OBJECTIVES: Few studies have been conducted in Saudi Arabia to estimate the prevalence of visual impairment and its causes. The objective of this study was to estimate the prevalence of visual impairment, and identify its causes and associated factors among the adult population attending primary health care (PHC) centers in Aljouf province, in northern Saudi Arabia.DESIGN AND SETTING: A cross-sectional study during the year 2005 in PHC centers in Aljouf province in northern Saudi ArabiaPATIENTS AND METHODS: A sample of 620 Saudi adults, of age 18 years and older, from the catchment area of the Aljouf PHC centers, were randomly selected through a multistage random sampling technique. Data were collected using a questionnaire about socioeconomic and related information and a visual acuity test was performed using the Snellen chart (E). Diagnosis was established according to World Health Organization (WHO) criteria. Visual impairment was categorized into blindness for a visual acuity of less than 3/60 (20/400, 0.05) in the better eye with the best correction and low vision for a best corrected visual acuity of less than 6/18 (20/60, 0.3) but not less than 3/60 (20/400, 0.05) in the better eye. Regression analysis was used to identify the predictors of visual impairment.RESULTS: Of 617 adult Saudis interviewed and examined, 269 (43.6%) were females. The mean (SD) age was 38.6 (16.2) years. The overall prevalence of visual impairment was 13.9% (95% CI: 11.4%-16.9%). The main medical causes of visual impairments were refractive errors (36.0%) followed by cataract (29.1%) and diabetic retinopathy (20.9%), and the least leading cause was glaucoma (5.8%). The most prominent determinants of visual impairment were age (P
