Diagram of the eye, the retina, and location of the various retinal implants. Retinal layers, from bottom to top: retinal pigment epithelium (RPE), photoreceptors (PR), horizontal cells (HC), bipolar cells (BC), amacrine cells (AC), ganglion cells (RGC), nerve fiber layer (RNFL).
A retinal implant is a visual prosthesis for restoration of sight to patients blinded by retinal degeneration. The system is meant to partially restore useful vision to those who have lost their photoreceptors due to retinal diseases such as retinitis pigmentosa (RP) or age-related macular degeneration (AMD). Retinal implants are being developed by a number of private companies and research institutions, and three types are in clinical trials: epiretinal (on the retina), subretinal (behind the retina), and suprachoroidal (between the choroid and the sclera). The implants introduce visual information into the retina by electrically stimulating the surviving retinal neurons. So far, elicited percepts had rather low resolution, and may be suitable for light perception and recognition of simple objects.
