Gene therapy makes blind puppies see Scientists have used gene therapy to make blind puppies see.
It's the first time an animal born without sight has had the sense repaired using this method. The work could help develop a treatment for people with a rare, inherited eye disorder. Three dogs, each with a condition similar to Leber congenital amaurosis, were treated. Scientists used a virus to carry healthy copies of the one damaged gene into the puppies' eyes. They injected the virus into just one eye on each dog and waited to see if it would produce the missing protein which caused the blindness.
