Cells taken from the donated eyes of dead people may be able to give sight to the blind, researchers suggest.
Tests in rats, reported in Stem Cells Translational Medicine, showed the human cells could restore some vision to completely blind rats.
The team at University College London said similar results in humans would improve quality of life, but would not give enough vision to read.
Human trials should begin within three years.
Donated corneas are already used to improve some people's sight, but the team at the Institute for Ophthalmology, at UCL, extracted a special kind of cell from the back of the eye.
These Muller glia cells are a type of adult stem cell capable of transforming into the specialised cells in the back of the eye and may be useful for treating a wide range of sight disorders.
