Abstract: Objective  To analyze the incidence and related factors of diabetic retinopathy(DR) in patients with type 2 diabetes mellitus(T2DM).Methods  A total of  3 404  inpatients with T2DM were studied retrospectively. According to the results of ophthalmic consultation,  the patients were divided into three groups,  including 2 562 cases ofnonDR group (group A/NDR),  716 cases of  non proliferative DR group (group B/NPDR),  and 126 cases of  proliferative DR group (group C/PDR).The incidence of DR was obtained,  then the differences and similarities in clinical data and clinical indicators among three groups were compared,  as well as  the  prevalence of DR.Results  The incidence rate of  DR  in T2DM patients was 24.7%,  which was correlated associated with triglyceride (OR=1.110,  P=0.000),  glycosylated hemoglobin (HbA1c) (OR=1.087,  P=0.000),  serum uric acid (OR=1.003,  P=0.000),  course of disease (OR=1.002,  P=0.000).Conclusion  The incidence rate of  DR in T2DM  patients was 24.7%, and hyperlipidemia,  hyperglycemia,  hyperuricemia,  long course of disease were independent risk factors for DR.Early detection and treatment of diabetes, active control of blood glucose, lipids and uric acid are of great significance to reduce the occurrence of DR and delay the development of DR.
