Optogenetic Therapy Shows Promise in Restoring Vision for Advanced Blindness

An international study published in The New England Journal of Medicine reports that an experimental optogenetic therapy has achieved a critical safety milestone and demonstrated measurable, and in some cases clinically meaningful, improvements in visual function for individuals with advanced retinitis pigmentosa. The therapy involves a gene injection to make retinal nerve cells light-sensitive, paired with specialized goggles. While not restoring normal vision, six out of ten participants showed clinically meaningful improvements in light sensitivity, and some could better locate objects and navigate.
