AIM: To explore the risk factors for type 2 diabetic retinopathy(DR)process.

METHODS: Totally 125 patients with type 2 DR were selected. The fundus performance, course of disease, blood pressure, glycated hemoglobin(HbA1c), lipids, C peptide, urine microalbumin, smoking, snoring and waist/hip ratio were analyzed.

RESULTS:DR severity and duration of disease, HbA1c, lipids, urine microalbumin, smoking, snoring and waist/hip ratio were positively correlated.

CONCLUSION: Longer duration, glucose metabolism and lipid metabolism disorders, smoking and snoring are risk factors for type 2 DR. Urinary albumin content can indirectly reflect DR severity.
