Abstract

AIM: To compare ocular blood flow parameters in Type 2 diabetic patients with or without retinopathy using the Color Doppler imaging(CDI) and correlate it with progression of Diabetic Retinopathy(DR).

METHODS: 120 patients, 27 without and rest with evidence of DR were assessed using CDI to evaluate ocular blood flow parameters at presentation and after 6 months. Peak Systolic Velocity(PSV), End Diastolic Velocity(EDV) and Resistive Index(RI) were recorded in the Ophthalmic Artery(OA) and the Central Retinal Artery(CRA).

RESULTS: The baseline RI were higher, 13 patients had progression in 6 months and showed significant increase in the RI of OA(p=0.0001) and the CRA(p=0.0006). EDV was also raised in the CRA (p=0.047).

CONCLUSION: The ocular blood flow appears to be progressively affected in all diabetics with DR. Significant changes in RIs of OA and CRA along with altered flow velocity in CRA could be useful to predict individuals at higher risk for developing progression of DR.
