Retina degenerations including age-related macular degeneration (AMD) and retinitis pigmentosa (RP) are common diseases causing blindness. Studies show that although the photo receptors in patients’ retina are damaged, most of the vision neurons remain attached, making current stimulation possible to restore vision. Application specific integrated circuit (ASIC) plays an important role in the development of retinal prosthesis. In this paper, the development of ASIC in retinal prosthesis is firstly reviewed. Architecture and chip designs of an ASIC for 128-channel retinal prosthesis are then introduced and the test results are presented.
