ALBUQUERQUE, N.M. - Enabling the blind to see - a task once thought the province of miracles - is the goal of a technical team that includes Sandia National Laboratories, four other national labs, a private company, and two universities. The idea, funded by a $9 million, three-year grant from the Department of Energy's Office of Biological and Environmental Research, is to create 1,000 points of light through 1,000 tiny MEMs [microelectromechanical systems] electrodes. The electrodes will be positioned on the retinas of those blinded by diseases such as age-related macular degeneration and retinitis pigmentosa. These diseases damage rods and cones in the eye that normally convert light to electrical impulses, but leave intact the neural paths to the brain that transport electrical signals. Eventually the input from rods and cones ceases, but 70 to 90 percent of nerve structures set up to receive those inputs remain intact.
