According to the Seattle Times, researchers Jay and Maureen Neitz from the University of Washington may have found a one-time treatment that cures colour blindness. The technique would use a modified virus in order to deliver a payload of DNA, allowing the missing proteins necessary for full colour vision to be produced.

“For 10 years, we have been trying to figure out a way to get the genes to go to the back of the eye with a simple shot,” said Neitz.

Now, with the help of Avalanche, the researchers say they’ve developed a technique that does just that. It uses a safe vector, called an adeno-associated virus, to house the pigment gene, which is injected directly into the vitreous, the jellylike center of the eye. Once, there, it targets cells on the back of the retina, said Thomas W. Chalberg Jr., the co-founder and chief executive of the firm.
