Methods This is a non-interventional, cross-sectional study of 300 diabetic Greek patients attending the Ophthalmology Department of a tertiary hospital. Clinical and imaging data were recorded and statistical analysis was performed. Confidence intervals (CI) at 95% and statistically significant p values <= 0.05 were set. Results A total of 300 diabetic patients were included. Of these patients, 21 (7%) were diagnosed with diabetes mellitus (DM) type I and 279 (93%) with DM type II. The average duration of diabetes was 15 +/- 9.4 years (95% CI 13.9-16.1) and the mean level of HbA1c was 7.2 +/- 1.3 (95% CI 7.1-7.4) overall. Prevalence of DR was 38.7% (116 patients), only 15 patients (5%) had proliferative DR and DME was detected in 19 patients (6.3%). In DM type I patients, 52.4% had DR and 9.5% had DME, while in the DM type II group, 37.6% had DR and 6.1% had DME. Binary logistic regression analysis identified duration of diabetes, increased HbA1c and hypertriglyceridemia as potential risk factors. Conclusions This study is the first one to present the extent and severity of DR and DME in a Greek cohort of diabetic patients and also identify risk factors associated with these entities. Our findings highlight the significance of a properly organized national screening program for the early detection and management of the vision-threatening complications of DR. 收起
