Retinal Transplant a Mixed Success

The technique used by the team at the University of Louisville, Kentucky, saw them implant the foetal retinal cells alongside cells which have the job of nourishing them, with the hope that the new cells would join forces with the existing retinal cells to improve overall vision.

Dr Norman Radtke, who led the project, said that sight tests showed no change in three of the 10 patients, but slight improvements in the rest. However, the improvements were only modest, and eyesight was well short of normal vision.
