We present a series of patients with diabetes mellitus (DM) who attended an eye hospital in Sana, Yemen during 2004.
To determine the magnitude and risk factors of diabetic retinopathy (DR).
Cross-sectional study.
Ophthalmologists assessed vision, ocular pressure, ocular media and posterior segment to note ocular manifestations among patients with DM. DR was graded by using bio-microscope and Volk lens. The prevalence and 95% confidence interval of ocular complications of DM were calculated. Risk factors of DR like age, sex, duration of diabetes and hypertension were evaluated.
Univariate and multivariate analysis.
Our series comprised 350 patients suffering from DM. The duration of diabetes was > or =15 years in 101 (29%) patients. Physician was treating 108 DM patients with insulin. The prevalence of DR was 55% (95% CI 49.6-60.1). The proportions of background diabetic retinopathy (BDR), preproliferative diabetic retinopathy (PPDR), proliferative diabetic retinopathy (PDR) and diabetic macular edema were 20%, 13%, 17% and 22% respectively. The prevalence of blindness among DM patients was 16%. The prevalence of cataract and glaucoma was 34.3% and 8.6%. Duration of DM was the predictor of DR. One-fifth of the patients had sight-threatening DR and needed laser treatment.
DR was of public health magnitude among our patients. An organized approach is recommended to address DR in the study area.
我们报告了 2004 年在也门萨那一家眼科医院就诊的一系列糖尿病患者。
确定糖尿病视网膜病变（DR）的严重程度和危险因素。
横断面研究。
眼科医生评估视力、眼压、眼内介质和后节，以记录糖尿病患者的眼部表现。使用生物显微镜和 Volk 透镜对 DR 进行分级。计算 DM 眼部并发症的患病率和 95%置信区间。评估 DR 的危险因素，如年龄、性别、糖尿病和高血压持续时间。
单变量和多变量分析。
我们的系列包括 350 名患有糖尿病的患者。101 名（29%）患者的糖尿病病程> =15 年。108 名糖尿病患者由医生用胰岛素治疗。DR 的患病率为 55%（95%CI 49.6-60.1）。背景性糖尿病视网膜病变（BDR）、前增生性糖尿病视网膜病变（PPDR）、增生性糖尿病视网膜病变（PDR）和糖尿病性黄斑水肿的比例分别为 20%、13%、17%和 22%。糖尿病患者失明的患病率为 16%。白内障和青光眼的患病率分别为 34.3%和 8.6%。糖尿病病程是 DR 的预测因素。五分之一的患者有威胁视力的 DR 并需要激光治疗。
DR 在我们的患者中具有公共卫生意义。建议在研究区域采取有组织的方法来解决 DR 问题。
