Gene Therapy for Blindness in London

A breakthrough gene therapy at a London eye hospital offers hope for children with severe visual impairment. A four-year-old child of Turkish descent received gene therapy to replace a faulty gene with a healthy copy, allowing better functioning of retinal cells.

Since 2020, gene therapy has been successfully used in the UK for another type of genetic blindness. The treatment involves injecting a healthy gene into the retina through a keyhole technique. The healthy gene, carried by a harmless virus, replaces the faulty gene, initiating a process that improves the functioning of cells at the back of the eye.

The mother of one of the children undergoing gene therapy shared, "Before the surgery, he couldn't follow an object held close to his face. Now he picks up things from the floor, plays with his toys, and does things he couldn't do before by seeing." It's important to note that while these improvements are significant, they do not indicate complete recovery.

Prof. James Bainbridge, the lead surgeon at Moorfields Eye Hospital and one of the directors of the experimental treatment, emphasized the potential impact of such progress on children's development. The team will continue to monitor the children to assess the long-term effects of the treatment.
