Objective To explore the relevant factors of diabetic retinopathy(DR).Methods 400 patients with type 2 diabetes were selected,and the relevant factors with DR of type 2 diabetes were analyzed.Results The incidence of DR in type 2 diabetes was 49.0％.In type 2 diabetes when diabetes duration＞15 years,the incidence of DR was 84.7％,duration＜5-year incidence rate was 30.0％ respectively,there were significant differences(P＜0.05).Incidence rate in lower blood glucose group and poor glycemic control group were 38.1％ and 68.5％ respectively,and there was statistically difference(P＜0.05),and in normal blood pressure and well control group,the incidence rates were 44.1％ and 41.2％,which were significantly better than 80.0％ of poorly controlled hypertension group.Conclusion Duration of diabetes,glycemic control level,blood pressure,exercise,and regular schedule were related factors of DR.The most important thing of DR treatment and prevention was to control blood glucose.
