Definition

Epiretinal prosthesis refers to the device designed to restore partial vision for the blind people by stimulating the retina through electrodes on the retina surface.

Overview

Introduction to Retina

Vision is the main method for people obtaining information from the outside world. Unfortunately, it has been estimated that there are about 250 million blind patients in the world, and the number is increasing year by year. Researchers have tried many ways to address the causes of blindness. Electrical stimulation has been proposed as a means to restore some sight for blind patients. The idea behind this is similar to what has been done in cochlear implants, where electrical stimulation of hair cells in the inner ear has been used to successfully restore the hearing for the deaf people [1]. In retinal prosthesis, electrical pulses are being delivered to the retina, invoking a neural response that corresponds to the information of...
