[Increased ocular perfusion--visual field preservation]

Abstract

Adjustment of the ocular flow has clear implications in glaucomatous pathology. It cannot be drawn a clear barrier between causality and effect of ocular vascular factor in glaucoma but altered hemodynamics leads clearly to node loss. Unstable ocular perfusion creates a low blood flow to the optic nerve directly involved in glaucomatous optic neuropathy , ocular perfusion pressure (PPO) being a risk factor predictor of progression associated with impairment of visual function in glaucoma.
