Photo: Color-blindness Cured by Gene Injection in Monkeys



Dalton the squirrel monkey, which was treated for red-green color blindness, samples a feast of fruits and vegetables. The digitally altered image on the left shows what a color-blind person (or monkey) would see.

A simple injection of cells cured monkeys, including Dalton, of color-blindness, giving the green light for future research into treating debilitating human eye diseases with gene therapy, a September 2009 study says.
