Stem cell breakthrough for blind patients ‘after treatment restores vision’



In the largest study of its kind, Italian researchers said they restored the sight of patients left blinded or suffered severely impaired vision, after suffering chemical burns.
Experts said the study, undertaken between 1998 and 2007, offers new hope to the thousands of people who suffer chemical burns on their corneas from heavy-duty cleansers or other substances at work or at home.

The research is also being hailed as a key breakthrough in scientific regeneration that could give hope to other patients with otherwise irreversible eyesight.
In the study, reported in the New England Journal of Medicine, researchers successfully extracted adult stem cells from healthy eye tissue before growing additional stem cells that were placed over damaged eye tissue.
The scientists extracted stem cells from the limbus of the patient’s healthy eye, growing them into a thin sheet and, ultimately, grafting it to the eye to create a clear regenerating cornea. Only one square millimeter of limbus tissue was required.
The treatment was successful in more than three quarters of the 112 patients, allowing them to see well again, although some needed more than one graft.
