目的。用四场立体彩色摄影技术评估印度城市地区2型糖尿病受试者中糖尿病视网膜病变(DR)的患病率。金奈城乡流行病学研究(CURES)是一项以人口为基础的研究，对印度南部金奈(前马德拉斯)的代表性人口进行了研究。年龄=20岁的个体(n=26,001)进行了糖尿病筛查。在1529名已知糖尿病受试者中，1382人(90.4%)参与了这项研究。口服葡萄糖耐量试验(OGTT)新发现的糖尿病患者(n=354)也同意参加这项研究。所有受试者均行四场立体彩色摄影，并根据早期治疗糖尿病视网膜病变研究(ETDRS)标准对彩色眼底照片中的视网膜病变进行分级。人群中DR的总患病率为17.6%(95%可信区间：15.8-19.5)，其中已知糖尿病患者为20.8%(95%CI：18.7-23.1)，新发现糖尿病患者为5.1%(95%CI：3.1-8.0)。男性DR患病率(21.3%)显著高于女性(14.6%；P
Purpose. To assess the prevalence of diabetic retinopathy (DR) in type 2 diabetic subjects in urban India using four-field stereo color photography.Methods. The Chennai Urban Rural Epidemiology Study (CURES) is a population-based study conducted on a representative population of Chennai (formerly Madras) city in South India. Individuals >= 20 years in age (n=26,001) were screened for diabetes. Of the 1529 known diabetic subjects, 1382 (90.4%) participated in the study. Subjects with newly detected diabetes (n=354) by the oral glucose tolerance test (OGTT) also consented to participate in the study. All the subjects underwent four-field stereo color photography, and retinopathy was graded in the color fundus photographs according to Early Treatment Diabetic Retinopathy Study (ETDRS) criteria.Results. The overall prevalence of DR in the population was 17.6% (95% confidence interval [CI]: 15.8-19.5), which included 20.8% (95% CI: 18.7-23.1) in known diabetic subjects and 5.1% (95% CI: 3.1-8.0) in subjects with newly detected diabetes. The prevalence of DR was significantly higher in men than in women (21.3% vs. 14.6%; P
