Researchers at the University of Bern have succeeded in restoring vision to blind mice. They have developed a molecular light switch as a potential therapy for acquired blindness. <\/b><\/span><\/p>\n<\/p>\n About one in 300 people suffer from complete or partial blindness associated with retinal degenerative diseases such as retinitis pigmentosa, an hereditary and so far incurable condition. Although the light-sensing cells lose their function, cells in deeper layers of the retina, which normally receive and process the visual information, remain intact. Scientists at the Department of Physiology<\/link> of the University of Bern<\/link> have discovered how to make those surviving retina cells light-sensing, thus turning them into \u201creplacement light sensors\u201d. <\/span><\/p>\n<\/p>\n The researchers treated mice suffering from retinitis pigmentosa with their newly developed therapy. As a result, the mice were able to see under daylight conditions, react to visual stimuli and learn visually triggered behaviors. The study was published in the journal \u201cPLoS Biology\u201d<\/link>. <\/span><\/p>\n<\/p>\n This new approach could help all patients suffering from blindness caused by photoreceptor degeneration \u2013 one of the most prevalent causes of blindness \u2013 but also people suffering from age-related macular degeneration, a condition that affects one in ten over-65 year olds to some extent.<\/span><\/p><\/p>\n","protected":false},"excerpt":{"rendered":" Researchers at the University of Bern have succeeded in restoring vision to blind mice.
