Sight of man with retinitis pigmentosa partially restored

The BBC has reported that the vision of a completely blind man has been partially restored using light-sensing proteins first found in algae. The man, who has retinitis pigmentosa, was treated with a type of therapy called optogenetics, which uses the proteins to control cells at the back of his eye.

You can read the BBC report on their website. Retina UK, the organisation for people affected by inherited progressive sight loss, has responded to the news and cautioned that several years of clinical testing will be required before the treatment can be considered for widespread use.
