最近一、二十年来,随着玻璃状体研究工作的进展,临床上对于玻璃状体改变与视网膜脱离关系的认识也渐深入,因而在检查和治疗方面,都有不少新的发展。1956年,Shafer 氏报告应用玻璃状体移植术(Vitreous implant)治疗视网膜脱离。这种手术,特别是对于再手术的病例,有一定的意义,也是视网膜脱离手术治疗方面一项新的内容。因目前国内尚未见到这方面的报导,故本文予以简单介绍,并将与此有关的一些问题作一重点复习。一、玻璃状体的结构及其某些特性玻璃状体是一种清沏透明的半固体凝胶。它充满在晶状体后面的眼球腔内,占眼球容积的三分之二,与晶状体后囊、睫状体、视网膜以及视神经乳头相接界。其前面附着于睫状体上皮,呈宽2—3毫米之环
In the recent one or two decades, with the progress of vitreous research, the clinical understanding of the relationship between vitreous body changes and retinal detachment has gradually deepened. Therefore, there are quite a few new developments in the examination and treatment. In 1956, Shafer reported the use of Vitreous implants to treat retinal detachment. This surgery, especially for the case of re-operation, has some significance, but also a retinal detachment surgical treatment of a new content. Because at present we have not yet seen this report, so this article will give a brief introduction, and will focus on some of the issues for review. First, the structure of the vitreous and some of its characteristics vitreous is a clear and transparent semi-solid gel. It fills the eyeball behind the lens, accounting for two-thirds of the eyeball volume, and the posterior capsule of the lens, the ciliary body, the retina, and the optic nerve junction. Its front attached to the ciliary body epithelium, was wide 2-3 mm ring
