Abstract

Retinitis pigmentosa and age-related macular degeneration leads to blindness through progressive loss of retinal photoreceptors. This paper describes an epi-retina visual prosthesis intended to provide electrical stimulation of the remaining, post-degenerative retina in order to recover some useful vision. The system includes extraoccular image acquisition and processing, a telemetry link based on inductive coupling, and an implantable neuro-stimulator for retina stimulation
