Groundbreaking gene therapy gives the gift of sight to Quebec child | 24CA News
Two retinologist surgeons on the Maisonneuve-Rosemont Hospital ophthalmology clinic in Montreal have carried out groundbreaking gene remedy on an 11-year-old boy.
The process was to reverse a degenerative, genetic eye illness that might have brought about him to go blind. It’s the primary operation of its sort in Quebec, and the primary publicly funded one in Canada.
The surgeons carried out the surgical procedure on William Khayrallah’s eyes two weeks aside, with the primary surgical procedure on his proper eye occurring on May 18. The docs surgically administered Luxturna, a gene remedy drug developed within the United States. The second surgical procedure was carried out on May 29.
“To convert an untreatable disease into a treatable disease, for a physician in their lifetime in their career, it’s very rare,” mentioned Dr. Flavio Rezende, an ophthalmologist and retinologist surgeon.
“It’s a very special opportunity we have to impact medicine into the future, and the future is the present. It’s very rewarding.”
William was first recognized with Leber’s congenital amaurosis as a child. It’s a extreme type of inherited retinitis pigmentosa brought on by a mutation within the RPE65 gene.
“I think for the child and the family when they first find out, it’s a very devastating diagnosis because in the past it was untreatable,” mentioned Dr. Cynthia Qian, certainly one of Khayrallah’s surgeons. “It leads to difficulties in vision in the dark at first, but over time this can continue to decrease to affect daytime vision.

“The treatment we are doing today is gene therapy to reverse the effects of this type of retinitis pigmentosa,” mentioned Dr. Qian.
“This is the first in the province of Quebec. It’s also the first gene therapy approved to completely reverse the disease at source. What we are able to do is to inject and surgically impact the gene in the patients affected in order to correct the genetic error and to re-establish the normal function of vision, and not only stabilize the vision but also keep it at a long-term permanent level.”
William says it took a couple of week for his eye to really feel higher after his first surgical procedure, however says his imaginative and prescient is remarkably improved since.
“It’s a big improvement from before and it’s life-changing for me,” William mentioned. “I played soccer with my dad at 8:30 at night and I was in goal and I managed to block the ball. This will be something I remember forever. It will be the thing I will never forget.”
