目的：了解上海市社区糖尿病患者的糖尿病视网膜病变(diabetic retinopathy，DR)的患病率及其对DR的认知度。

方法：对社区慢病档案中记录和确诊为糖尿病的患者545例开展眼科检查和DR防治知识调查问卷，了解DR的患病率，用χ²检验分析患病率的差异，并将糖尿病患者对DR防治知识的掌握情况进行描述性统计分析。

结果：社区糖尿病患者DR患病率为23.5%，其中非增殖期和增殖期患病率分别为20.9%和2.6%。社区糖尿病患者对DR的认识度不高，并存在较多误区。

结论：利用慢病档案对糖尿病患者开展眼科检查可以做到使DR从社区开始预防，糖尿病患者对DR的认知度还需要提高。

METHODS: A total of 545 diabetic patients in the community's chronic disease file were enrolled in the Ophthalmologic Examination and DR Prevention Questionnaire. To know the prevalence rate of DR and to use chi-square test to check analysis the difference of prevalence rate. The descriptive statistical analysis of DR prevention and treatment knowledge was carried out in diabetes.

RESULTS: The prevalence of DR was 23.5%. And the prevalence of non-proliferative retinopathy and proliferative retinopathy was 20.9% and 2.6%. The patients with diabetes in the Huamu Community lacked sufficient awareness of DR prevention and treatment methods.
