A system for electrical retinal stimulation for human trials

The goal of the Retinal Implant Project is to restore useful vision to patients with degenerative diseases of the retina. Electrical stimulation of the retina via a microelectrode array is achieved using a battery powered stimulation system. This thesis describes the design of this system, including features that ensure the subject's safety from electrical shock. The stimulation system delivers charge balanced current pulses to the 100 electrodes in the array. The system has been tested in the laboratory setting as well as in rabbit experiments and one human retinal stimulation trial. It functions as specified, and is very robust.
