Breakthrough in vision restoration
A recent study that won the 2026 Nobel Prize revealed that gene-based visual therapy can restore some vision abilities in the blind caused by retinitis pigmentosa. This treatment involves injecting light-sensitive proteins into modified retinal cells, then using special glasses to convert visual information into patterns that stimulate the cells and transmit signals back to the brain. The experiment, which included 10 patients, showed light sensitivity improvements in seven of them, along with enhanced abilities to detect and locate objects, despite experiencing a temporary adverse event after the injection. The results confirm that it is possible to make retinal ganglion cells responsive to light even in advanced stages of blindness, although further studies are needed to confirm the benefits.
