ULTRASONOGRAFIA DOPPLER ÎN GLAUCOMUL CU ALTERARE PERIMETRICĂ ASIMETRICĂ.

With color Doppler imaging we attempted to quantify the retrobulbar hemodynamics in glaucoma patients with asymmetric visual field losses. The peak systolic and end-diastolic blood flow velocities and resistivity indices of the ophthalmic, short posterior ciliary and central retinal arteries were measured. We performed visual field examination, intraocular pressure (IOP) and blood pressure measurements. The study revealed reductions in the flow velocities and increases in the resistance indices of the retrobulbar vessels, despite similar intraocular pressure (IOP) curves in both eyes. These changes correlate with disease severity and asymmetry of visual field losses and illustrate a compromised retrobulbar hemodynamics [ABSTRACT FROM AUTHOR]
