AbstractAim: To determine the importance of HbA1C levels and normotension in predicting the development of diabetic retinopathy and the relationship between them.
Method: Prospective clinical study comprising of a group of 125 diabetics above 40 years visiting for routine eye checkup and clinically diagnosed diabetic retinopathy including both out-patient and in-patients at Department of Ophthalmology, KIMS, Bangalore. Men and women >40years with type 2 diabetes mellitus with HbA1C levels <7.5% and non-hypertensives (<140mmHg systolic and <90mmHg diastolic pressure) were included. Patient’s HbA1C levels and blood pressure were measured. The diabetic retinopathy status was classified according to the ETDRS system. Statistical analysis was done.
Results: At 3rd month follow up, the mean HbA1C levels was 7.25±0.22.At the end of 12th month, the mean HbA1C was 7.42±0.11At baseline, in group A 8.8% showed mild NPDR and 1.6% moderate NPDR. At the end of the study it was 8.8% mild NPDR, 1.6% moderate NPDR. No further progression was seen in a year span. All values showed statistical significance and absence of hypertension also goes in favour of mild diabetic retinopathy changes.
Conclusion: HbA1C levels and systemic hypertension are the two major modifiable risk factors in the development and progression of diabetic retinopathy
