摘要:

经过生物技术、材料科学的发展及对视功能和视网膜神经科学的研究,目前主要有两种视网膜假体用于临床,分别是Argus II和alpha\|IMS。视网膜假体主要通过获取图像、图像转化、内层视网膜产生激动的途径来部分重建外层视网膜的功能,使视觉信息通过视神经传递到视皮质,达到视觉重建的目的。

Abstract:

With the advances in biotechnology, material science and understanding of visual and retinal neuroscience, there are two kinds of retinal prostheses in clinical practice now: Argus II and alpha\|IMS. The retinal prostheses can partly rebuild the function of outer retinal by image capture, image translation, and inner retina activation, from where visual information can be relayed to the visual cortex by the optic nerve.
