Comparison of Established Risk Factors among Type 2 Diabetic Patients with or without Retinopathy in Golestan Hospital, Ahvaz 2010

The aim of this study was to establish diabetic retinopathy correlation with several risk factors. A prospective study including 256 type II diabetic patients who referred to diabetes’s clinic was designed. All patients underwent physical & retina examination and then completed questionnaire including duration of DM, cardiovascular disease, stroke, chronic kidney disease, smoking, and kind of treatment, blood pressure, BMI, abdominal & hip circumference. Results of HbA1C, total cholesterol, HDL & LDL cholesterol, TG, FBS, creatinine, 24-h urine microalbumin were recorded. Data were analyzed by SPSS version 17 with K2, independent samples T, and logistic regression. Of 256 types II diabetic patients 81 & 175 were men and women respectively. Mean age of subject was 54 ± 10.27. Prevalence of diabetic retinopathy was 22.3% & macula edema 0.5% & PDR 6% & NPDR 14%; diabetic retinopathy was associated with duration of DM & BMI (P = 0, P = 0.43 respectively). Mean of FBS 191 ± 83 vs. 165.7 ± 74.5 (P = 0.03), HbA1c 9.1 ± 2 vs. 8.5 ± 1.9 (P = 0.02), 24-h urine microalbumin 181.2 ± 404.7 vs. 60.2 ± 236 (P = 0.03), Systolic blood pressure 124.3 ± 21.3 vs. 118.5 ± 17.8 (p = 0.04) differed between diabetic patients with or without diabetic retinopathy. There were no significant difference between subject with & without diabetic retinopathy in total cholesterol LDL, HDL, TG, Cr, Diastolic BP, types of treatment, cardiovascular disease, chronic kidney disease, stroke & smoking. This study showed prevalence of diabetic retinopathy was high and it associated with duration of DM, BMI, FBS, HbA1C, 24-h urine albumin, and systolic blood pressure.
