Blind mice see after cell transplant
Study offers clues to eye regeneration
By Gareth Cook, Globe Staff | November 9, 2006
Researchers announced yesterday that they have restored vision in mice by implanting new light-sensing cells in their eyes, a scientific first that offers hope to millions of blind people.
The team, based in London, said it has discovered a way to transplant the cells that provide night vision, known as "rods," from a healthy mouse into blind ones. The cells took root in the retina, and the mice's pupils then dilated when exposed to light.
A similar approach, the scientists said, might be used to replace the cells that provide daytime color vision.

This won't work for people who never developed sight to begin with because the part of the brain that deals with processing images atrophies in the absence of input.
Can you not work it up to "match fit" over time?
