目的：探讨社区2型糖尿病视网膜病变发生的相关影响因素。方法对社区252例2型糖尿病(T2DM)患者进行眼底检查及血糖、血脂测定，对糖尿病视网膜病变(DR)患者和无糖尿病视网膜病变(NDR)患者的基本情况及血糖、血脂等指标进行比较分析。结果 DR患者与NDR患者比较，糖尿病病程、空腹血糖(FBG)、餐后2 h血糖(2hBG)、糖化血红蛋白(HbA1c)、总胆固醇(TC)、甘油三酯(TG)和低密度脂蛋白(LDL-C)差异有统计学意义(<0.05)。结论社区2型糖尿病视网膜病变的发生与T2DM患者病程长、血糖、血脂等指标控制不良相关，在社区开展DR早期干预非常必要。“,”Objective To analyse the related risk factors of incidence of diabetic retinopathy in type 2 diabetes mellitus patients in community. Methods Totally 252 cases with type 2 diabetes mellitus (T2DM) in yinhu community in shenzhen were divided into group diabetic retinopathy(DR) and group non-diabetic retinopathy (NDR) by examining fundus, and investigated basic condition,level of blood sugar and blood lipid.Results Compared with the outlets between group DR and NDR ,the duration of T2DM,fasting blood-glucose (FBG),2h post-meal blood glucose (2hBG), glycosylated haemoglobin(HbA1c ),total cholesterol(TC),triglyceride(TG) and low density lipoprotein-cholesterol(LDL-C) were statistically significant ( <0.05).Conclusion The incidence of DR is related to the long duration of diabetes patients,poor control on blood sugar and blood lipid.It is very necessary of early prevention against DR in community.
