视觉是人类对周围世界最重要的感觉之一。视觉剥夺不仅明显影响盲人的生活，而且给家庭和社会带来沉重的负担。视觉假体是一种通过植入人体的微电极直接刺激视觉通路来帮助盲人恢复视觉感知的电子装置。近年来，视觉假体得到了迅速发展，并且一些设备已经成为临床可用。本文回顾了视觉假体的发展历史，介绍了按刺激电极植入位置分类的各种视觉假体。还总结了临床研究结果以及目前可用的视觉假体装置的功能状态。
Vision is one of the most important human sensations about the surrounding world. Visual deprivation not only markedly affects the life of blind people, but also gives a heavy burden to their family and the society. A visual prosthesis is an electronic device that helps the blinds to regain visual perception by directly stimulating the visual pathway using the microelectrodes implanted into the body. In recent years, visual prostheses have been developed rapidly and some devices have already become clinically available. In this paper, we reviewed the history of visual prosthesis, introduced different visual prostheses classified according to the location of the implanted stimulating electrodes. Clinical study results as well as the functional status of the currently available visual prosthesis devices were also summarized.
