title: The role of optic nerve blood flow in the pathogenesis of glaucoma.
abstract: Many theories have surfaced regarding the exact mechanisms behind glaucomatous damage, but the complex nature of the disease and the inaccessibility of the internal structures of the human eye have limited current knowledge. Increased intraocular pressure is the risk factor most often associated with glaucomatous optic neuropathy; ischemic insult to the optic nerve has also been suggested as a possible cause of cellular damage. The aim of this review is to cover the possible role of optic nerve head hemodynamics in the pathogenesis of glaucoma.
