A mutation in the NPHP5 gene leads to a severe blinding disorder, Leber congenital amaurosis. Dogs with the condition that were treated with a gene therapy regrew normal, functional cone cells, labeled in red, that had previously failed to develop. The treatment led to a recovery of retinal function and vision. (Image: Courtesy of Gustavo Aguirre and William Beltran)

Turning back the clock on a severe vision disorder
