Abstract		Purpose: To measure and investigate changes of blood flow velocity by color Doppler imaging in the ophthalmic artery (OAI, central retinal artery (CRA) and short posterior ciliary arteries (PCA) in diabetic retinopathy (DR) and to compare the results with those in healthy control subjects. Methods: In this investigation we included 44 eyes of 44 diabetic patients with different stages of DR forming group NPDR (11 eyes with mild and 11 eyes with moderate nonproliferative DR) and group SNPDR/PDR 119 eyes with severe nonproliferative and 3 eyes with proliferative DR) and 22 eyes of 22 healthy age-and sexmatched subjects forming control group HC. With color Doppler imaging we measured the peak systolic velocity (PSV, cm/s) and end-diastolic velocity (EDV, cm/sl of blood flow in the OA, CRA and PCA.The resistance index of each vessel was then calculated. Statistical analysis comparing the results of groups NPDR, SNPDR/PDR and HC was carried out. Statistical significance was set at p < 0.05. (Abstract truncated at 2000 characters)
