During the tests, the patient was able to locate and touch a notebook on a table in front of him 92% of the time while wearing the goggles. Without them, he was unable to perform any visual task.
Scientists have for the first time managed to partially restore the sight of a blind patient by altering his cells, according to the results of a . 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.More Related News
