老年性黄斑变性是老年人视力丧失的重要原因之一,它包括玻璃疣、灶性萎缩、反应性视网膜色素上皮增生以及视网膜色素上皮浆液性脱离等。以前认为色素上皮浆液性脱离的主要并发症是来自脉络膜的血管侵入色素上皮下腔,形成血管性盘状病变。1981Hoskin首次报道视网膜色素上皮脱离的另一个并发症—视网膜色素上皮撕裂在临床上较常见,对视力危害很大。最近陆续有一些文献报道,本文综述这种病变的临床表现以及目前关于其发病机理的探讨。
Age-related macular degeneration is one of the important causes of vision loss in the elderly. It includes drusen, focal atrophy, reactive retinal pigment epithelial hyperplasia, and retinal pigment epithelium serous detachment. It was previously thought that the major complication of serous detachment of the pigment epithelium is the invasion of blood vessels from the choroid into the subepithelium of the pigment epithelium, forming a vascular discotic lesion. 1981Hoskin for the first time reported another retinal pigment epithelial detachment complications - retinal pigment epithelium tear in the clinic more common, great harm to vision. Recently some have reported in succession, this article summarizes the clinical manifestations of this lesion and the current study on its pathogenesis.
