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 …

Retinal prosthesis systems have undergone significant advances in the past quarter century,
resulting in the development of several different novel surgical and engineering approaches …

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 …

Prosthetic vision is being applied to partially recover the retinal stimulation of visually
impaired people. However, the phosphenic images produced by the implants have very …

Loss of sight significantly degrades the quality of human life. Various methods for restoring
the vision of blind patients have been studied and range from biological ways to electronic …

The bypassing of degenerated photoreceptors using retinal neurostimulators is helping the
blind to recover functional vision. Researchers are investigating new ways to improve visual …

Objective. Epiretinal prostheses are designed to restore vision in people blinded by
photoreceptor degenerative diseases, by directly activating retinal ganglion cells (RGCs) …

A future artificial retina that can restore high acuity vision in blind people will rely on the
capability to both read (observe) and write (control) the spiking activity of neurons using an …

Objective. Visual outcomes provided by present retinal prostheses that primarily target
retinal ganglion cells (RGCs) through epiretinal stimulation remain rudimentary, partly due to …

The ability for visual prostheses to preferentially activate functionally-distinct retinal ganglion
cells (RGCs) is important for improving visual perception. This study investigates the use of …
