视网膜是眼球最重要的眼内组织,是视觉系统中的前哨。组织学上共分为十层,最外层为视网膜色素上皮,起源于视杯外层;其余九层为神经视网膜,由视杯内层分化而来。视网膜色素上皮(RPE)与神经视网膜(简称视网膜)相比,组织结构上看来相对简单,但功能上却十分复杂,其对视觉的影响至关紧要,必须予以重视。近代视觉研究中,视网膜色素上皮是众所关注的课题之 The retina is the eye’s most important intraocular tissue and is the outpost in the visual system. Histologically divided into ten layers, the outermost retinal pigment epithelium, originated in the outer cup; the remaining nine layers of the neural retina, from the differentiation of the optic disc inner layer. Retinal pigment epithelium (RPE) compared with the neural retina (Retina for short), the organizational structure seems relatively simple, but the function is very complex, its visual impact is crucial, we must pay attention. In modern visual studies, retinal pigment epithelium is a topic of public concern
