Perceptual learning in retina implant users

Retinal implants (RI) are photoelectric devices that enable otherwise blind patients residual vision due to electrical stimulation of the retina. The perception gained by retinal implants ( RI) is limited by the design of the implant on the one hand and by physiological factors on the other hand (for a recent review see Shepherd et al., 2013). Great progress has been made in the development of RI systems and surgical procedures, leading to certified medical products. In contrast, to our knowledge no scientifically validated perceptual learning programs exist that help the RI patients to make optimal use of their implants. The potential usefulness of perceptual learning regimes derives from the severe limitations of visual perception that current RI technology can offer. In this situation, patients may substantially benefit from learning to recognize objects and scenes in the degraded visual signals that RIs deliver.
