Israeli and American researchers at Stanford University are developing a "bionic eye", solar-powered device that stimulates nerve cells in the eye and blindness can heal people suffering from retinitis pigmentosa, a degenerative disease of the retina.
The research is funded by the USAF (United States Air Force) and is supported by the U.S. National Institute of Health. According to the researchers, led by Daniel Palanker - Israeli scientist of the Department of Ophthalmology at Stanford - the device, a plate of silicon super thin 30 microns thick, is implanted under the patient's retina through a simple surgical procedure. The board includes hundreds of photovoltaic cells that convert sunlight into electricity.
One outdoor camera is affixed to a pair of sunglasses that capture the image, as well as Google Display Optical Glass, design the image in the eye and increase light levels.
The board receives the image and converts it into nerve signals that stimulate the retina. Thereafter, the device acts like a human eye, with nerve cells sending information to the brain.
Yossi Mandel, a leading researcher at Stanford University, told Haaretz during a visit to Israel that the operation to implant the prosthetic retina is relatively easy compared to products currently available, and a plate implanted beneath the retina allows rats (during testing) see as clearly as someone who naturally has a good vision.
Other companies are developing similar products, such as the Israeli startup Nano Retina and Bionic Vision Australia.
The main cause of blindness among Israelis is a disease that affects the retina known as AMD (age-related macular degeneration). However, this disease that affects more than 10 percent of people over 60 years of age is not a target for an artificial retina implant as it affects primarily the edges and not the center of the retina, allowing a limited view similar retina Artificial under development.
