OCULAR BLOOD FLOW ASSESSEMENT BY COLOR DOPPLER IMAGING IN GLAUCOMA
Abstract:
Altered perfusion of the optic nerve head is a pathogenetic factor in glaucomatous optic
neuropathy.Besides increased intraocular pressure, disturbed microcirculation in the optic nerve had no
doubt contribution of the glaucomatous optic neuropathy progression.Colour Doppler imaging
measures the blood flow velocities and vascular resistivity in retrobulbar vessels.The use of this
investigation reported lower velocities in ophthalmic artery, central retinal artery and short posterior
ciliary artery and increases in downstream vascular resistance of the vessels of glaucoma patients
compared with healthy controls.
