Three women suffered severe, permanent eye damage after stem cells were injected into their eyes, in an unproven treatment at a loosely regulated clinic in Florida, doctors reported in an article published Wednesday in The New England Journal of Medicine.
One, 72, went completely blind from the injections, and the others, 78 and 88, lost much of their eyesight. Before the procedure, all had some visual impairment but could see well enough to drive.
