Single gene therapy injection surprisingly boosts vision in both eyes


One of the ways scientists hope to offer better treatments for vision loss is through gene therapy, where carefully selected genetic material is injected into the eyes to address mutations. Researchers have been left surprised by the effectiveness of an experimental form of this treatment, which involved an injection into one eyeball yet improved vision across both.

Gene therapies have the potential to treat all kinds of health conditions, ranging from cancer, to diabetes in dogs, to obesity and damaged spinal cords. One area where we’re seeing some really exciting progress is in hereditary vision loss, with studies demonstrating the potential of gene therapy to treat color blindness, progressive retinal diseases and glaucoma, with some recently receiving approval from the FDA.
