A drug can restore the ability of the eye to sense light after blindness, animal studies show.
Reacting to light is the job of the rods and cones in the retina, but these can be destroyed by disease.
A study, in the journal Neuron, showed a chemical could give "support-duty cells" in the eye the power to respond readily to light.
Experts said it was a fascinating concept which might lead to treatments, but stressed more research was needed.
