Abstract

AIM: To compare ocular blood flow parameters in Type 2 diabetic patients using the
Color Doppler sonography and correlate it with the progression of Diabetic
Retinopathy.
METHODS: 120 diabetic patients, were assessed using Colour Doppler imaging to evaluate the ocular blood flow in the retrobulbar circulation at first presentation and after six months. Peak Systolic Velocity, End Diastolic Velocity and Resistive Index were recorded in the Ophthalmic Artery and the Central Retinal Artery.
RESULTS: The baseline resistive indices were higher and 13
patients developed progression in the last six months and showed significant increase
in the Resistive Index of Ophthalmic Artery(p=0.0001).
CONCLUSION: Significant changes in Resistivity Indices of Ophthalmic Artery and Central Retinal Artery could be useful to predict individuals at higher risk for developing progression of Diabetic Retinopathy.
