A new device designed to treat Macular Degeneration and Retinitis Pigmentosa has been developed and is under review. Artificial Silicon Retinas™ (ASR) are 2 mm silicon chips about the thickness of paper. They were first implanted in the retinas of three people in 2000. Each chip has 3,500 microscopic solar cells, each with an electrode designed to stimulate remaining retinal cells from underneath the retina in a pattern resembling the light images focused on the chip. The chips are completely self contained and receive their power from the light that enters the eye. They require no wires or batteries. |

The chip was invented by Dr. Alan Cnow and his electrical engineer brother, Vincent Chow. For more information on the Artificial Silicon Retina™, please visit the Optobionics website at www.optobionics.com .
Other devices are being investigated. At Johns Hopkins Hospital in Baltimore a device is being developed which involves the use of a small external camera which transmits an image to an implanted chip placed near the ganglion cells.
