| 摘 要： | 视觉通路上的任何疾病都会影响视觉信号的传导,严重者甚至导致不可逆性盲.视网膜假体的研究是指在视网膜的不同部位植入相应的视网膜微电极,由植入物产生电信号或者释放神经递质,刺激并激活视网膜细胞产生神经冲动,从而使盲人或濒于盲的眼重新获得有用或部分有用视力.笔者分别介绍3类视网膜假体的结构组成、作用机制、植入方式、影响因素、优缺点及植入后效果和生物相容性等,以供同道参考.

| Abstract: | Any disease in visual pathway will affect the visual signal transmission, even more seriously, leading to irreversible blindness.The study of retinal prostheses is that retinal microelectrodes are implanted into different places of retina, and retinal microelectrodes set off electrical signals or deliver neurotransmitters, so as to excite and activate retinal neurons.This review describes the construction,mechanism, way of implantation, influencing factor, advantage and shortcoming, effect of post implantation,biocompatibility of 3 types of retinal prostheses. |
