New gene therapy restores night vision of people with inherited eye disorder

Two people with a rare inherited eye disorder have had their night vision restored by an experimental gene therapy, researchers say. 

These two individuals are part of an ongoing clinical trial (opens in new tab) testing the safety and effectiveness of the new gene therapy, the research team wrote in a report published in October in the journal iScience (opens in new tab). This and additional trials will need to be completed before the therapy can be approved for widespread use, but these early data hint that the treatment can spur “remarkable gains” in patients’ night vision, the scientists wrote.
