We measured the blood flow velocity in the ophthalmic artery in 49 eyes with proliferative diabetic retinopathy. We used a color Doppler imaging unit SSA-260A (Toshiba). The obtained median values were: 0.30m/sec for maximum velocity, 0.05m/sec for minimum velocity, 0.13m/sec for mean velocity and pulsatility index of 1.91. Nonparametric statistic analysis showed a significantly reduced value for each parameter than in age-matched controls. Severity of proliferative retinopathy was negatively correlated only with pulsatility index. The blood flow velocities were significantly correlated with the age and not with the duration of diabetes, total plasma cholesterol or HbA1c, Above findings suggested contribu-tion of diabetic macroangiopathy to the decreased flow velocity in the ophthalmic artery in proliferative diabetic retinopathy.
