A collaboration of researchers from the University of California, the University of Washington and the University of Munich have discovered a chemical that has the ability to restore sight in mice. The results are only temporary at the moment, but the researchers hope that they can develop a more stable compound that could help patients with degenerative blindness to regain their sight.
The chemical, known as AAQ, makes the remaining retina cells sensitive to light. The researchers describe AAQ as a photoswitch that attaches itself to protein ion channels on the retina cells. When the light hits the cells, the AAQ activates in the same way as the rods and cones do in a normal functioning eye. [Read more...]
