视网膜假体通过电刺激仍然存活的视网膜神经节细胞，部分恢复了晚期视网膜色素变性失明患者的视力。我们调查了迟发性盲人在数十年失明后通过视网膜假体部分恢复视力后是否能够进行视觉-触觉形状匹配。我们测试了视觉-视觉、触觉-触觉和视觉-触觉的二维形状匹配，包括6名Argus II视网膜假体患者、10名视力对照和8名具有模拟超低视力的视力对照。在Argus II患者中，视觉-视觉形状匹配性能显著高于Chance。虽然Argus II患者的视觉-触觉形状匹配性能并不显著高于Chance，但随着假体使用时间的延长，其显著更高。使用自然视力的视力控制组和模拟超低视力的视力控制组都比Argus II患者更准确地完成视觉-视觉和视觉-触觉形状匹配任务。在Argus II患者和有或没有模拟超低视力的视力对照组之间，触觉-触觉匹配没有显著差异。这些结果表明，有经验的视网膜假体患者可以跨感官匹配形状，并将人工视觉与体感相结合。视网膜假体患者的跨模式形状匹配性能与设备使用时间的相关性支持了经验对跨模式形状学习的价值。这些在Argus II患者身上的跨模式形状匹配结果是了解人工视觉修复后跨模式知觉的第一步。
Retinal prostheses partially restore vision to late blind patients with retinitis pigmentosa through electrical stimulation of still-viable retinal ganglion cells. We investigated whether the late blind can perform visual–tactile shape matching following the partial restoration of vision via retinal prostheses after decades of blindness. We tested for visual–visual, tactile–tactile, and visual–tactile two-dimensional shape matching with six Argus II retinal prosthesis patients, ten sighted controls, and eight sighted controls with simulated ultra-low vision. In the Argus II patients, the visual–visual shape matching performance was significantly greater than chance. Although the visual–tactile shape matching performance of the Argus II patients was not significantly greater than chance, it was significantly higher with longer duration of prosthesis use. The sighted controls using natural vision and the sighted controls with simulated ultra-low vision both performed the visual–visual and visual–tactile shape matching tasks significantly more accurately than the Argus II patients. The tactile–tactile matching was not significantly different between the Argus II patients and sighted controls with or without simulated ultra-low vision. These results show that experienced retinal prosthesis patients can match shapes across the senses and integrate artificial vision with somatosensation. The correlation of retinal prosthesis patients’ crossmodal shape matching performance with the duration of device use supports the value of experience to crossmodal shape learning. These crossmodal shape matching results in Argus II patients are the first step toward understanding crossmodal perception after artificial visual restoration.
