Abstract:
Objective: To investigate the hemodynamic changes of ophthalmic artery(OA) and central retinal artery(CRA) in patients with primary angle-closure glaucoma(PACG) and the effects of intraocular pressure(IOP) on retrobulbar hemodynamics. Methods: Following the measurement of IOP by non-contact tonometry,hemodynamic changes of OA and CRA were examined by color Doppler imaging(CDI) in 45 patients(90 eyes) with PACG,who were divided according to IOP into a hypertension(38 eyes) and a normal tension group(52 eyes).Observations were made of the peak systolic velocity(PSV),end-diastolic velocity(EDV),pulsatility index(PI) and resistance index(RI).Results: Significant differences were found between the PACG patients and the normal controls in CRA-EDV(P
