Totally blind mice get sight back
It's the first proof that you can take a completely blind mouse, put the cells in and reconstruct the entire light-sensitive layer”
- Prof Robert MacLaren University of Oxford
Totally blind mice have had their sight restored by injections of light-sensing cells into the eye, UK researchers report.
Experts said the field was advancing rapidly, but there were still questions about the quality of vision restored.
Patients with retinitis pigmentosa gradually lose light-sensing cells from the retina and can become blind.
