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.
视觉通路中的任何疾病都会影响视觉信号的传递，甚至更严重地导致不可逆的失明。视网膜假体的研究是将视网膜微电极植入视网膜的不同部位，视网膜微电极发出电信号或释放神经递质，从而激发和激活视网膜神经元。本文综述了3种视网膜假体的结构、机制、植入方式、影响因素、优缺点、植入后的效果及生物相容性。
