Stem cell transplantation can offer hope of blindness, after a British experiment that showed that this procedure improves the vision of patients with severe visual impairment in just 18 months.
The trial, in which 16 patients with corneal cell deficiency participated, revealed that stem cell transplantation from donor corneas provided patients with improved vision. Scientists have found that it reduces pain in patients and facilitates activities such as reading. Although the trials are still in their infancy, they are "promising" and show the possibility of safe stem cell surgery.
The University of Edinburgh conducted this experiment under the direction of Professor Palin Dillon. "The results of the trial are very promising and show the possibility of safe surgery as well as improvements in vision care."
"Our next step is to better understand how stem cells can promote tissue repair to treat diseases that are very difficult to treat and how they can help improve vision."
The researchers badyzed data from 13 patients with corneal stem cell deficiency. In recent experiments, stem cells were obtained from corneal samples taken from the eyes of a donor within 24 hours of his death.
