Giving Eyesight to the Blind
Gene therapy could potentially restore to those suffering from blindness

Three young adults with virtually no vision can now read several lines on an eye chart and see better in dimly lit settings thanks to an innovative gene therapy aiming to reverse blindness in a severe form of retinitis pigmentosa known as Leber congenital amaurosis or LCA. One person was even able to better navigate an obstacle course several weeks after receiving the therapy.

The three individuals are participating in a Phase I clinical trial at The Children's Hospital of Philadelphia, which is funded in part by the Foundation Fighting Blindness.
