Scientists have prompted mouse-eye cells that aren't normally light sensitive to respond to light. This strategy could lead to new treatments for retinitis pigmentosa and related diseases, which cause blindness in 1 in 3,000 people worldwide.
To restore vision in people who have lost these cells, scientists have suggested several strategies, such as growing rods and cones from stem cells or replacing them with synthetic chips that sense light. But so far, these approaches face myriad challenges. Neuroscientists say these preliminary findings offer a novel approach to treat blinding diseases.
