[Advanced research in the retinal prosthesis].
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.
