Abstract

PURPOSE-

To assess the blood flow velocity by color doppler imaging (CDI) of retrobulbar vessels in eyes with primary open angle glaucoma ( POAG) .

METHOD- A prospective case control study was done on 20 newly diagnosed POAG patients (POAG group) and 20 control patients (control group). Color doppler imaging was performed by ultrasound machine using linear high frequency probe.

RESULT-All the patients with POAG had raised RI and decreased EDV in both the OA and CRA. The increase in IOP in POAG group was negatively correlated with PSV and EDV and positively correlated with RI for both the OA and CRA.

CONCLUSION-Retrobulbar hemodynamics alterations represent a risk factor for glaucoma progression even in early stages when the visual fields are normal. CDI of ocular blood flow can be used as potential diagnostic tool for early diagnosis of glaucoma , enabling early intervention to prevent progressive irreversible vision loss.
