The Argus II 60 channel epiretinal prosthesis has been developed in order to provide partial restoration of vision to subjects blinded from outer retinal degenerative disease. To date the device has been implanted in 21 subjects as part of a feasibility study. In 6 month post-implantation door finding and line tracking orientation and mobility testing, subjects have shown improvements of 86% and 73%, respectively, for system on vs. system off. In high-contrast Square Localization tests using a touch screen monitor 87% of tested subjects performed significantly better with the system on compared with off. These preliminary results show that the Argus II system provides some functional vision to blind subjects.
阿格斯二代60通道视网膜假体已被研发出来，旨在为因外层视网膜退行性疾病而失明的患者提供部分视力恢复。到目前为止，作为一项可行性研究的一部分，该设备已被植入21名患者体内。在植入后6个月的门识别、线条追踪定向和移动性测试中，与系统关闭相比，系统开启时患者分别显示出86%和73%的改善。在使用触摸屏显示器的高对比度方块定位测试中，87%的受试患者在系统开启时的表现明显优于系统关闭时。这些初步结果表明，阿格斯二代系统为盲人患者提供了一定的功能性视力。
