Los Angeles – Dozens of people who were blinded or otherwise suffered severe eye damage when they were splashed with caustic chemicals had their sight restored with transplants of their own stem cells–a stunning success for the burgeoning cell-therapy field, Italian researchers reported Wednesday. ** The treatment worked completely in 82 of 107 eyes and partially in 14 others, with benefits lasting up to a decade so far. One man whose eyes were severely damaged more than 60 years ago now has near-normal vision. ** “This is a roaring success,” said ophthalmologist Dr. Ivan Schwab of the University of California, Davis, who had no role in the study–the longest and largest of its kind. ** In the study, published online by the New England Journal of Medicine, researchers took a small number of stem cells from a patient’s healthy eye, multiplied them in the lab and placed them into the burned eye, where they were able to grow new corneal tissue to replace what had been damaged. Since the stem cells are from their own bodies, the patients do not need to take anti-rejection drugs.
