Gene therapy improves vision for patients facing blindness

Medical researchers in Oxford say they have managed to improve the sight of patients who were going blind because of a rare genetic disorder.

Writing in the medical journal, The Lancet, they say that genes - injected into the patients' eyes - revitalised light detecting cells.

It is hoped it may be possible to extend the treatment to some other conditions that cause loss of vision.
