Hereditary blindness cure tested
A virus carrying corrective DNA into cells at the back of the eye is being tested to treat one of the most common forms of hereditary blindness in young men and boys. It targets XLRP (X-linked retinitis pigmentosa), which is progressive and currently incurable.
Professor Robert MacLaren of Oxford University is the leader of this first trial on patients in the UK and told Newsday how this gene therapy treatment works.
