Objective To study the influencing factors of retinal vessel caliber in type 2 diabetes mellitus and supply the elementary data for clinic. Methods Two hundred diabetic patients were involved in this study, and the vessel caliber was measured by fundus oculi color photo and computer-assisted imaging program. Biochemical indicator and blood pressure was examined and other document was achieved by questionaire. Results In type 2 diabetes mellitus, the retinal vein caliber had negative correlation with age and positive correlation with fasting blood glucose (FBG), glycosylated hemoglobin A1c (HbA1c) and the duration of diabetes mellitus(P < 0.01 ). The retinal arteriole caliber had negative correlation with age, blood pressure and the duration of diabetes mellitus (P < 0.01 or < 0.05 ).
