Correlation of Ocular Biometric Parameters with the Severity of Diabetic Retinopathy

Abstract

Diabetic retinopathy (DR) is a common complication of diabetes and one of the leading causes of blindness worldwide. Early detection and intervention are key to preventing vision loss in diabetic patients. Ocular biometric parameters, such as axial length, anterior chamber depth, and corneal thickness, are important in assessing eye health. This study aims to explore the correlation between ocular biometric parameters and the severity of diabetic retinopathy in patients with diabetes mellitus. A cross-sectional study was conducted involving 100 diabetic patients who underwent ocular biometric measurements and fundus examination to classify the severity of DR based on the Early Treatment Diabetic Retinopathy Study (ETDRS) scale. Results showed significant correlations between axial length and DR severity, with longer axial lengths associated with milder stages of DR. Additionally, a thinner central corneal thickness was observed in patients with more advanced stages of DR. These findings suggest that ocular biometric parameters may serve as adjunctive tools in assessing the severity of DR and could potentially assist in predicting the progression of diabetic retinopathy.
