Experimental and Clinical Studies of Retinal Stimulation
University of Michigan
Summary
The study will evaluate new methods of retinal stimulation and training with the goal of improving the visual ability of retinal prosthesis participants.
Description
The study will test new ways to make the retinal prosthesis visual perception easier with auditory-visual training and how to make the retinal prosthesis work better at perceiving shapes.
