Artificial Retinas Bring Vision Back To The Blind

Patters writes "Researchers from the University of California and the Doheny Eye Institute have successfully implanted a tiny electronic eye implant with a video camera mounted on a pair of sunglasses into 6 patients, allowing them to detect light and motion. The implant is a 4-by-4 grid of electrodes which connects to damaged photoreceptors (rods and cones) on the patient's retina. It works by stimulating the photoreceptors, transmitting signals through the optic nerve to the brain. The implant only works on patients with degenerated rods and cones, and is named after Argus, the Greek god which had 100 eyes. If the implants continue to be a success, the artificial retinas could be available to the public within the next 3 years."
