A 38-year-old man in Italy has regained his sight after undergoing experimental gene therapy for Usher syndrome type 1b, a condition causing deafness and progressive vision loss. The surgery, conducted in July 2024 at the University of Campania, involved injecting viral vectors under the retina. A year later, the patient reported significant improvements in his vision, allowing him to live more independently. The operation marks a significant advancement in gene therapy for genetic eye disorders, with plans for further trials.
