青光眼是一种严重致盲眼病 ,目前越来越多的研究表明 ,眼压升高并不是导致青光眼视神经损害的唯一因素 ,视神经乳头微循环障碍的变化正日益受到重视。本文就视神经乳头的正常解剖生理、脉络膜循环与视神经乳头血液供应的关系以及原发性开角型青光眼、单纯性视神经萎缩、多发性硬化疾病对视神经乳头微循环的影响加以综述。 Glaucoma is a serious eye-blind disease. At present, more and more studies show that elevated intraocular pressure is not the only factor that causes glaucomatous optic nerve damage. The changes of optic nerve microcirculation are receiving more and more attention. In this paper, the normal anatomy and physiology of the optic nerve head, the relationship between the choroidal circulation and the blood supply of the optic nerve head, and the effects of primary open-angle glaucoma, simple optic nerve atrophy and multiple sclerosis on the microcirculation of optic nerve head are reviewed.
