Holography + optogenetics = bionic vision? Maybe someday

Computer-generated holography could artificially stimulate cells in the eye and even lead to a new strategy for bionic vision restoration, say researchers at Technion-Israel Institute of Technology. Holography could be used in conjunction with optogenetics on damaged retinal nerve cells. In conditions such as retinitis pigmentosa, which affects about 1 in 4000 people in the US, these light-sensing cells degenerate, leading to blindness. The optogenetic approach photosensitizes the nerve cells so that they can be activated by intense pulses of light. But researchers around the world...Read full article
