AIM: To investigate the risk factors of diabetic retinopathy(DR)in type 2 diabetes patients.

METHODS: A total of 380 cases of type 2 diabetes were selected from January 2014 to June 2014, divided into DR group(126 cases)and non-diabetic retinopathy(NDR)as control group(254 cases), all patients were underwent medical history, physical examinations, laboratory and assistance examinations. The prevalence and single factor and multiple factors of DR were analysed by the logistic regression model.

RESULTS: The univariate logistic regression analysis showed that DR was associated with diabetes duration, systolic blood pressure, triglyceride, total cholesterol, low-density lipoprotein, urine protein, intraocular pressure, carotid intima-media thickness, peripheral neuropathy disease was the related risk factors for DR. In multiple logistic regression analysis, only duration was the related risk factors for DR.

CONCLUSION: The occurrence of DR is the outcome of combined action of multiple factors, duration is an independent risk factor for occurrence of DR.
