Input: Eli Wheatley and Christian Guardino are among a growing number of patients whose lives are apparently being saved or radically improved by gene therapy.
 Guardino  was diagnosed with a different condition â Leber's congenital amaurosis  a disease of the eye's retina â when  he  was born. The disorder isn't fatal. But it was destroying his vision.
"I wouldn't be able to walk around outside on my own " says  Guardino . During the day   he  says  the world looked "incredibly dark" and blurry. "It was sort of like watching your world fade away."

Now  Guardino  can see things  he 'd only dreamed about.
After the gene therapy treatment   he  says  "I was able to see things for the first time â like the moon. I was able to see stars for the first time â fireworks â all these amazing things that I've never been able to see before."
