US scientists have found a potential treatment for blindness in patients with retinal disorders, that affect around 200 million people worldwide.
Using donor human cadaver eyes, researchers at the Mount Sinai School of Medicine, New York, US, transplanted retinal pigment epithelium cells, which regulate normal vision, into the retina of partially sighted non-human primates.
Their results, published in Stem Cell Reports, show at least partial restoration of vision in the monkeys, with no serious side effects.
