Scientists are testing out ways to restore vision for genetic-caused blindness

Fox News Flash top headlines are here. Check out what s clicking on Foxnews.com. Scientists are making dramatic strides toward a goal that once seemed almost unimaginable: Restoring limited vision to people affected by a previously irreversible form of blindness caused by an inherited eye disease called retinitis pigmentosa. In a paper published Monday in the journal Nature Medicine, researchers working with the Paris-based company GenSight Biologics SA reported that a 58-year-old man who was diagnosed with retinitis pigmentosa 40 years ago was able to locate objects placed on a table after receiving an experimental therapy. And New York City-based company Bionic Sight LLC announced in March that four blind people in an early-stage clinical trial are now able to detect light and motion after undergoing a similar treatment. Those results haven’t yet been published.

Scientists restore partial sight in blind man

AFP/ MANILA BULLETIN The technique known as optogenetics, which has been developed in the field of neuroscience over the last 20 years, involves genetically altering cells so they produce more light-sensitive proteins. In some cases of blindness, known as inherited photoreceptor diseases, light-sensing cells in the retina that use proteins to deliver visual information to the brain via the optic nerve progressively degenerate. Scientists in Europe and the US recruited a man who had lost his sight due to an inherited photoreceptor disease 40 years ago and began treating him with optogenetic techniques. This involved injections in his eye and several months of stimulation with light emitting goggles, which transformed images of the visual world into light pulses projected into the retina in real time.
