Scientists Are Making Stunning Advances In Curing Blindness

• Business Insider

Already, bionic retinas enable blind people to "see" sidewalks, doorways and even oversized text while gene therapy has allowed a small boy to put away his white cane and take up Little League baseball.

Drugs are being used to halt some age-related forms of blindness, and in lab dishes, stem cells are being coaxed into forming retinal tissue in early proof-of-concept work.

"Things that were thought impossible a few years ago are a reality today," Maria Canto-Soler, director of the Retinal Degeneration Research Centre at Johns Hopkins University in the United States told AFP.

"It wouldn't be appropriate to say that we will find ways to cure retinal degenerative diseases in just a few more years, but we are surely on the right track... it is just a matter of time."
