Abstract :

 Diabetic retinopathy (DR) is a major microvascular complication of diabetes mellitus. The Early Treatment Diabetic Retinopathy Study (ETDRS) identified HbA1c as one of the most important risk factors for the progression to high risk proliferative retinopathy. Aim was to study the association between Glycosylated Haemoglobin and Severity of Diabetic Retinopathy in Type 2 Diabetic patients Methodology: It was cross sectional study wherein 500 type 2 diabetics with duration of diabetes >15years were included. Retinopathy was graded according to ETDRS and HbA1c assessed. Statistical analysis of the data was done by using SPSS software Results: The mean HbA1c in patients with no DR, NPDR and PDR was 6.76 ±1.3, 8.99±1.89, and 11.045 ±1.53 respectively. Conclusion: Elevated HbA1c is associated with higher prevalence of DR. We also found that the higher values of HbA1c is associated with increase in severity of retinopathy.
