Gene Therapy Reverses Sight Loss and Is Long-Lasting
April 29, 2016
(BBC) – A genetic therapy has improved the vision of patients who would otherwise have gone blind. A clinical study by British scientists has shown that the improvement is long-lasting and so the therapy is suitable to be offered as a treatment. The researchers will apply for approval to begin trials to treat more common forms of blindness next year. The therapy involve injecting working copy of the gene into the back of the eyes to help cells regenerate. The results of the therapy, published in the New England Journal of Medicine, have been tried out on 14 patients in the UK and 18 in the US, Canada and Germany over the past four and a half years.
