Purpose: To evaluate the color Doppler imaging (CDI) and pattern visual evoked potential (P-VEP) examinations in primary open angle glaucoma (POAG) patients and investigate the relation between flow velocities measured by CDI and P-VEP examination in POAG patients.
Methods: Sixty five POAG patients and 45 control subjects underwent CDI evaluation of the ophthalmic artery (OA), short posterior ciliary artery (SPCA) and central retinal arteries (CRA). The peak systolic velocities (PSV) and end-diastolic velocities (EDV) and resistive index (RI) of all retrobulbar vessels were measured. The latency and amplitude of P100 in P-VEP were recorded. The differences of CDI and P-VEP parameters among POAG and control groups were compared. The correlations between CDI parameters, visual field indices and P-VEP in POAG patients were evaluated by Pearson's .. View More»
