AIM:To investigate the risk factors of diabetic retinopathy in type 2 diabetic patients.

METHODS: The data of 1 013 patients with type 2 diabetes mellitus who admitted to hospital from January 2013 to April 2017 were retrospectively analyzed. Diabetic retinopathy patients were included in the observation group, and non diabetic retinopathy patients were included in the control group. Then the risk factors of diabetic retinopathy in type 2 diabetic patients were analyzed.

RESULTS: After investigation, the incidence of DR was 27.74%(281/1013). By univariate analysis, the differences of gender, age, duration of T2DM, blood pressure, HbA1c, HDL-C, creatinine and 24h urine protein between the two groups were statistically significant(P<0.05). Multivariate Logistic regression analysis showed that men, age more than 60 years, T2DM duration of more than 10a, and blood pressure, HbA1c, HDL-C, creatinine, and abnormal expression of 24h urinary protein were risk factors for DR in type 2 diabetes mellitus patients(P<0.05).

CONCLUSION: At present, the risk of DR in patients with type 2 diabetes is also higher. Men, age more than 60 years, T2DM duration of more than 10a, and blood pressure, HbA1c, HDL-C, creatinine, and abnormal expression of 24h urinary protein are risk factors for DR in type 2 diabetes mellitus patients.
