Purpose: The purpose of this study is to understand the correlation between HbA1C values and severity of disease in diabetic patients with diabetic retinopathy and diabetic patients without diabetic retinopathy. Methods: 47 patients with diabetes were examined at a tertiary center. All of these patients underwent tests like visual acuity, slit lamp examination, dilated fundus examination, blood tests including random blood sugars and HbA1C levels. Duration of the disease and medications taken were also noted for all the patients. Results: In this study, a total of 47 patients were evaluated with a mean age of 57.72 ± 12.42 years. 18 out of 27 patients (66.6%) with HbA1c values more than 10% showed signs of diabetic retinopathy with a mean HbA1c value of 12.5 ± 1.8 %. 4 out of 13 patients (30.7%) with HbA1c values between 6.9% to 10% showed signs of diabetic retinopathy with a mean HbA1c value of 8.7 ± 1.3 %. None of 7 patients with HbA1c values less than 6.9% showed signs of diabetic retinopathy. Conclusion: Higher levels of HbA1C levels and longer duration of disease are found to be associated with diabetic retinopathy disease.
