Prosthesis to Photo-Stimulate Retinal Neurons for Sight Restoration

Introduction It is estimated that 1 million people in the United States and 40 million worldwide are legally blind. Approximately 25% of these cases are caused by inactive photoreceptors in the eye. Macular degeneration and retinitis pigmentosa are the predominant causes, and there are currently no effective treatments available. Technology description Researchers at the University of Washington have developed a novel, minimally invasive approach to treat blindness caused by the degeneration of photoreceptors. The technology consists of a prosthetic device using camera-guided lasers, which create a virtual display on the degenerated retina. The laser beam uncages neurotransmitter molecules in the proximity of the retina enabling these molecules to activate ganglion and bipolar cells involved in photoreception. The activation of the retinal neurons results in “sight” at a resolution similar to average vision. Business opportunity This technology will be useful as a visual aid to people who are blind due to inactive photoreceptors because of diseases like macular degeneration and retinitis pigmentosa. Stage of development Initial data exist for this technology.
