Stem cell eye treatment safe, restores some vision: study
PARIS: Two people with severe vision loss due to a degenerative eye disease are able to read after embryonic stem cell treatment, researchers said Monday.
The pair suffer from "wet" age-related macular degeneration, which can blur vision or cause a blind spot when abnormal blood vessels leak fluids into the eye, causing damage to a layer of cells called the retinal pigment epithelium (RPE).
This damage to the retina kills light-sensing cells.
For the study, a British-American research team used human embryonic stem…
