Altering eye cells may one day restore vision

Doctors may one day treat some forms of blindness by altering the genetic program of the light-sensing cells of the eye, according to School of Medicine scientists. Working in mice with a disease that causes gradual blindness, the researchers reprogrammed the cells in the eye that enable night vision.

Gene scan helps identify cause of inherited blindness

Scientists at Washington University School of Medicine in St. Louis have scanned the entire genome of mice for genes that help build photoreceptors, the light-sensing cells of the eye. The results have already helped researchers identify the gene that causes a form of retinitis pigmentosa, a type of inherited blindness in humans.
