A new study which has suggested possible forms of treatment for blind people is "very encouraging news" for visually impaired people across the planet, one expert has claimed.
Dharmesh Patel, chairman of the charity the Eyecare Trust, said the research "clearly demonstrates" how developments in nanotechnology can eventually help to improve quality of life for the millions of people who suffer sight loss.
The study, carried out by German researchers and published in the journal Proceedings of the Royal Society B, found that an implant in the eye can help blind people to see certain shapes and light just three days after being inserted.
Mr Patel said the Eyecare Trust is now looking forward to seeing the results of further trials to test the efficacy of the treatment.
"If further trials prove successful it could represent a major advance in the way in which we treat retinitis pigmentosa, macular degeneration and other sight-threatening conditions," he added.
