Innovative Progress: "The Argus II Retinal Prosthesis System was recently granted market approval by the U.S. Food and Drug Administration (FDA), which marks a significant milestone in the development of a therapy that has spanned more than 20 years. It was at Johns Hopkins University, in the early 1990s, that I, along with Drs. de Juan, Humayun and Dagnelie, with some early support from FFB, carried out the very first short-term (one hour or so) experiments with human volunteers. We demonstrated that electrical stimulation of the retina could, indeed, produce spots of light perceived by blind patients."
