WEDNESDAY, April 4, 2018 (HealthDay News) -- A new stem cell transplant might help preserve or even restore vision being lost to the dry form of age-related macular degeneration, a new pilot clinical trial has shown.
In the experimental therapy, a specially engineered sheet of stem cells is transplanted into the back wall of the eye to replace a layer of cells destroyed by age-related macular degeneration (AMD).
Vision loss appeared to halt in four of the first five people treated with the implant cells, researchers reported in the April 4 issue of the journal Science Translational Medicine.
The fifth patient actually experienced some improvement in vision, and was able to read 17 additional letters off a standard eye chart, said lead researcher Dr. Amir Kashani. He is assistant professor of clinical ophthalmology at the University of Southern California's Keck School of Medicine.
