We assessed the causes of visual impairment and blindness in 694 diabetic patients attending our eye centre in Sana'a, Yemen from 2001 to 2005 by review of their medical records. The mean age of the patients was 53.9 (SD 11.52) years, range 13-95 years, and 382 (55%) were males. According to the World Health Organization definitions, 273 (39.3%) patients had visual impairment and 109 (15.7%) were blind. Cataract, proliferative diabetic retinopathy (PDR) and diabetic maculopathy were the main causes of visual impairment and blindness. Patients with PDR and maculopathy were significantly more likely to have visual impairment compared to patients without retinopathy (RR = 1.99, 95% CI: 1.74-2.28 and RR = 1.84, (95% CI: 1.60-2.13 respectively) and be blind (RR = 4.69, 95% CI: 3.70-5.95 and RR = 2.53, 95% CI: 1.92-3.34 respectively). Diabetic retinopathy is a public health problem in Yemen and national screening and educational programmes are highly needed to reduce the risk of visual impairment and blindness among diabetics.
我们通过查阅病历，评估了 2001 年至 2005 年在也门萨那我们的眼科中心就诊的 694 名糖尿病患者的视力障碍和失明原因。患者的平均年龄为 53.9（SD 11.52）岁，范围为 13-95 岁，其中 382 名（55%）为男性。根据世界卫生组织的定义，273 名（39.3%）患者有视力障碍，109 名（15.7%）失明。白内障、增殖性糖尿病视网膜病变（PDR）和糖尿病性黄斑病变是视力障碍和失明的主要原因。与无视网膜病变的患者相比，患有 PDR 和黄斑病变的患者视力障碍的可能性显著更高（RR=1.99，95%CI：1.74-2.28 和 RR=1.84，95%CI：1.60-2.13），失明的可能性也更高（RR=4.69，95%CI：3.70-5.95 和 RR=2.53，95%CI：1.92-3.34）。糖尿病视网膜病变是也门的一个公共卫生问题，需要开展全国性的筛查和教育计划，以降低糖尿病患者视力障碍和失明的风险。
