"After six months, the scientists re-tested the monkey's eyesight. Before the transplant, the monkey was able to focus its gaze on just 1.5 percent of dots in a series of tests. But six months into the transplant, the primate was able to fix its gaze on a significantly higher percentage, showcasing the promise of stem cells in treating vision impairment."
"Rather than patching the macular hole with the limited cells already in the eye, stem cells present the option of introducing new cells entirely, potentially restoring vision without losing peripheral sight."
