青光眼的科研工作始终围绕着病理性高眼压的病因和青光眼性视神经损害的发病机制这两个中心环节进行。Sears指出,视神对眼压升高的敏感性比眼压的高低更重要。因此本文的重点将论讨第二个问题。一、视网膜、脉络膜及视盘的解剖生理 (一) 视网膜神经纤维层的解剖视网膜神经纤维的走行及其在视盘表面的分布很有规律。Evans(1959)将视盘分成12等份,鼻、颞侧各6等份,黄斑区的神经纤维进入 Glaucoma research work has always centered around the pathogenesis of high intraocular pressure and glaucomatous optic nerve damage in the pathogenesis of these two aspects. Sears pointed out that optic nerve sensitivity to elevated intraocular pressure is more important than the level of intraocular pressure. Therefore, the focus of this article will discuss the second issue. First, the retina, choroid and optic disc anatomy and physiology (A) of the retinal nerve fiber layer dissection retinal nerve fiber and its distribution in the optic disc surface is very regular. Evans (1959) will be divided into 12 equal parts of the optic disc, nasal, temporal 6 equal parts, macular nerve fibers into
