Scientists Announce 'Big Leap' Towards Reversing Blindness
Animal study shows some parts of eyes can be repaired using stem cells
An animal study in the journal Nature Biotechnology showed the part of the eye which actually detects light can be repaired using stem cells.
The team at Moorfields Eye Hospital and University College London say human trials are now, for the first time, a realistic prospect.
Experts described it as a "significant breakthrough" and "huge leap" forward.
Photoreceptors are the cells in the retina which react to light and convert it into an electrical signal which can be sent to the brain.
However, these cells can die off in some causes of blindness such as Stargardt's disease and age-related macular degeneration.
