A new gene therapy has been used to treat patients with a rare inherited eye disorder which causes blindness.
It's hoped the NHS treatment will halt sight loss and even improve vision.
Matthew Wood, 48, one of the first patients to receive the injection, told the BBC: "I value the remaining sight I have so if I can hold on to that it would be a big thing for me."
The treatment costs around £600,000 but NHS England has agreed a discounted price with the manufacturer Novartis.
Luxturna (voretigene neparvovec), has been approved by The National Institute for Health and Care Excellence (NICE), which estimates that just under 90 people in England will be eligible for the treatment.
The gene therapy is for patients who have retinal dystrophy as a result of inheriting a faulty copy of the RPE65 gene from both parents. The gene is important for providing the pigment that light sensitive cells need to absorb light. Initially this affects night vision but eventually, as the cells die, it can lead to complete blindness.
