目的：介绍国内外主要视觉假体研究小组的工作现状，讨论未来研究的重点和难点。方法：回顾和介绍植入视皮层、视神经和视网膜的视觉假体的功能和特点，并分析其优缺点。结果：工程化和手术问题不再是未来发展的主要障碍，而障碍在于如何最好地将有意义的信息引入到视觉剥夺的大脑中。结论：到目前为止，还没有一种视觉假体能够在临床上恢复患者的功能性视力，开发足够的视觉植入物仍然需要不懈的努力。
Objective: The current work of the main visual prosthesis research groups abroad and at home is presented,and the focal point and the difficulty in future study are discussed.Methods: The function and characteristics of the visual prosthesis implanted in the visual cortex,the optic nerve and the retina is reviewed and introduced,and their advantages and disadvantages are analyzed.Results: The engineering along with the surgical issues is no longer a great impediment to future progress.Rather,the barrier lies in how to best introduce meaningful information to the visually deprived brain.Conclusions: Until now there is no visual prosthesis that can restore functional vision for the patients clinically,the development of sufficient visual implant still needs persistent efforts.
