Stem Cell Therapy Blinds Three Patients at Florida Clinic
Thursday, March 16, 2017 | Medical Studies
Three women with non-neovascular ("dry") age-related macular degeneration (AMD) experienced profound visual loss after receiving bilateral intravitreal injections of autologous adipose tissue-derived stem cells at a Florida clinic, according to a report published online today in the New England Journal of Medicine. "After 1 year, the patients' visual acuity ranged from 20/200 to no light perception," write Ajay E. Kuriyan, MD, from the Department of Ophthalmology, Bascom Palmer Eye Institute, University of Miami, Florida, and colleagues. These outcomes are "dramatically worse" than those of standard care for dry AMD, which is associated with moderate visual loss in 3.3% of patients in a year.
