Stem Cells Can Restore Vision


Some blind patients are able to see again with the help of a regenerative treatment that uses stem cells taken from the patient’s own eyes.

Such were the findings reported by Italian researchers: the stem cell procedure resulted in successful corneal transplantation in three-fourths of patients with blindness in one or both eyes, caused mostly by chemical or thermal burns.

On the other hand, in those patients who did not have major damage to other parts of the affected eye, at least vision was partially restored.

The study’s researcher Graziella Pellegrini, PhD of the University of Moderna’s Center for Regenerative Medicine and her team have performed corneal transplants in around 250 patients over the last decade using the said stem cell technique. However, the procedure remains experimental and is not being done in the United States.
