Retinal prostheses are designed to restore a basic sense of sight to people with profound
vision loss. They require a relatively intact posterior visual pathway (optic nerve, lateral …

Despite appearing automatic and effortless, perceiving the visual world is a highly complex
process that depends on intact visual and oculomotor function. Understanding the …

Vision is an extraordinary sense through which we can appreciate the beauty of the world
we live in, gain invaluable knowledge and communicate with others using visual expression …

Translational research in vision prosthetics, gene therapy, optogenetics, stem cell and other
forms of transplantation, and sensory substitution is creating new therapeutic options for …

Purpose: Visual scanning by sighted individuals is done using eye and head movements. In
contrast, scanning using the Argus II is solely done by head movement, since eye …

Background: Innovations in engineering and neuroscience have enabled the development
of sophisticated visual prosthetic devices. In clinical trials, these devices have provided …

Background Restoring sight for the blind using electrical stimulation of the visual pathways is
feasible but demands an understanding of the spatial mapping of the visual world at the site …

Importance There are no approved drug treatments for autosomal dominant retinitis
pigmentosa, a relentlessly progressive cause of adult and childhood blindness. Objectives …

Summary The new RETINA IMPLANT Alpha AMS shows significantly improved durability
compared with the predecessor model RETINA IMPLANT Alpha IMS. The subretinal implant …

Two of the main obstacles to the development of epiretinal prosthesis technology are
electrodes that require current amplitudes above safety limits to reliably elicit percepts, and a …
