Diabetic retinopathy is a common micro vascular complication of diabetes. The risk of diabetic retinopathy is closely associated with the type and duration of diabetes, blood glucose, blood pressure and lipid disorders. This study aims to compare features of type 2 diabetes patients with and without diagnosed diabetic retinopathy. The cross-sectional study includes 140 randomly selected type 2 diabetes patients. Patient`s general information was noted, anthropometrical measurements were conducted and blood was sampled for glucose metabolism, lipid and lipoprotein parameters and fibrinogen. 24-hour urine portion was sampled for proteinuria measurement. Fundus examination was performed by ophthalmology specialist using the 90 D biomicroscopy. For statistical analysis we used mean values, proportions, t-test, test of proportions and logistic regression. In group with diagnosed diabetic retinopathy there were 74 patients (68.92% had nonproliferative diabetic retinopathy and 31.08% had proliferative diabetic retinopathy) and most were male (p=0.0218). They were older (p=0.0009) and had longer duration of diabetes (p=0.0002). Waist circumference was significantly higher in this group (p=0.0018), and they had higher levels of proteinuria (p=0.0018). These patients more frequently used insulin (p<0.0001) and were less frequent on sulphonylureas (p=0.0030). Logistic regression showed independent association of gender, duration of diabetes, proteinuria and suplhonylureas usage with presence of diabetic retinopathy. Patients with diagnosed diabetic retinopathy are more often male. They are older and have longer duration of diabetes. Also, they are more centrally obese, have higher levels of proteinuria and are more frequent on insulin therapy and less frequent on sulphonylureas than patients without diabetic retinopathy.
