Evaluation of the Retina with a Subretinal Microphotodiode Array
VA Rehab R&D Merit Review # C2675CA

Description:
We are evaluating an experimental retinal prosthetic that would take the place of the degenerated photoreceptors in the diseased retina. This device is designed to be implanted in the subretinal space and directly stimulate the retinal cells in response to light.

Technology Evaluation Process:
Evaluation of current and new implant designs is being done via animal models in which ophthalmic, electrophysiological, and histological analysis can be performed to test implant biocompatibility, functioning, and efficacy.
