Abstract:
The hemodynamics of ocular artery (OA) and central retinal artery(CRA)in normal persons and patients (102 eyes, respectively)with primary open-angle glaucoma (POAG) were studied with color Doppler image technique. The results showed that average values of peak systolic flow velocity (Vmax), the end-diastolic flow velocity (Vmin) and the mean flow velocity (Vmeau)for the OA and CRA in glau-comatous patients we^e much lower than that in normal persons. But the mean resistance index (RI) was higher than that in normal persons. The linear regression analysis presented that there was a positive correlation of Vmin between the OA and CRA (r = 0.3278, p
