A Southern German team led by the University Eye Hospital inTübingen, was formed in 1995 by Eberhart Zrenner to develop asubretinal prosthesis. The chip is located behind the and utilizesmicrophotodiode arrays (MPDA) which collect incident light andtransform it into electrical current stimulating the . As natural are far moreefficient than , visible light is not powerfulenough to stimulate the MPDA. Therefore, an external power supplyis used to enhance the stimulation current. The German teamcommenced in vivo experiments in 2000, when evoked corticalpotentials were measured from Yucatan micropigs and rabbits. At 14months post implantation, the implant and retina surrounding itwere examined and there were no noticeable changes to anatomicalintegrity. The implants were successful in producing evokedcortical potentials in half of the animals tested. The thresholdsidentified in this study were similar to those required inepiretinal stimulation. The latest reports from this group concernthe results of a clinical pilot study on eight participantssuffering from . Theresults were to be presented in detail on the ARVO 2007 congress inFort Lauderdale.

Joseph Rizzo and John Wyatt at the Massachusetts Eye and EarInfirmary and MIT began researching the feasibility of a retinalprosthesis in 1989, and performed a number of proof-of-conceptepiretinal stimulation trials on blind volunteers between 1998 and2000. They have since developed a subretinal stimulator that sitson the outside of the eye and receives image signals beamed from acamera mounted on a pair of glasses. The stimulator chip decodesthe picture information beamed from the camera and stimulates accordingly.
