  "account": "Researchers have revealed that a type of gene therapy based on Nobel prize-winning science can partly restore sight in blind people. Known as optogenetic therapy, it involves using light to turn nerve cells on and off. This technique, which won the 2026 Nobel prize in physiology or medicine, was first shown to partly restore vision in a single blind person in 2021. In a larger trial involving the original patient and nine others, the results showed that the concept of optogenetics is valid for vision restoration.\n\nAll 10 participants had advanced retinitis pigmentosa, a genetic disorder affecting more than 1.5 million people worldwide. These disorders cause light-sensitive cells in the retina to gradually lose their function, but the ganglion cells, which send visual information to the brain, deteriorate less quickly. The therapy involves injecting a single dose into the eye, containing a harmless synthetic virus that delivers genetic instructions for producing a light-sensitive protein into surviving ganglion cells. This makes these cells light-sensitive.\n\nEach participant receives a pair of light-stimulating goggles that capture images of the world and convert them into pulses of light, activating the light-sensitive ganglion cells. This allows wearers to perceive a monochrome image. The technique doesn't depend on the exact genetic cause of the patient's sight loss. After the treatment, only one severe eye-related side-effect occurred, but it was resolved quickly. There were no side effects related to the therapy in the rest of the body.\n\nSix of the 10 participants showed clinically meaningful improvements in light sensitivity and some demonstrated improvements in tasks like detecting objects and navigating a line. However, participants cannot yet detect faces as the treated ganglion cells are arranged in a ring-like formation around the fovea, responsible for sharp central vision. The researchers are optimistic that with further advancements, high-resolution vision restoration could be achieved within five to 10 years.",
