ABSTRACT
Diabetic Retinopathy (DR) is most important cause of legal blindness between 20-70yr age group. The effect of prolonged hyperglycemia can be measured with the help of glycosylated haemoglobin (HbA1c). Intensive glycemic control had been proved to be effective in decreasing incidence rate of development and progression of DR in type 1 and type 2 DM. The present prospective study was conducted on 110 cases of DR which shows highly significant correlation (P<0.001) between HbA1c level and severity of diabetic retinopathy stages. However, among values of blood glucose level post prandial showed significant correlation (P-value<0.002) and whereas no significant correlation established in case of fasting values of blood glucose. (P>0.179). Thus our study revealed that PPBS has a closer association with HbA1c and better predictor for overall glycemic control.
