Abstract

Objective:To observe the ocular hemodynamic changes after rhematigenous retinal detachment. Methods: Ophthalmic artery(OA), and Central retinal artery(CRA) were studied with color Doppler imaging in 54 patients with unilateral rhematogenous retinal detachment, the fellow eyes served as control. The measured parameters included peak systolic velocity(Vmax), end diastolic velocity(Vmin) and resistance index(RI). Results: In the comparison with the control group, Vmax of OA and CRA was lower(P0.05), and RI of CRA was higher (P0.05). In older patients, Vmax of OA were more lower. Vmin of OA and CRA and RI of OA showed no significant abnormalities compared with that of the controls(P0.05). Conclusions: The OA and CRA blood flow velocity were low in retinal detachment. The velocity of OA had negative correlation with the age.
