Overview
- The 2026 Nobel Prize in Physiology or Medicine was awarded on Oct. 5 to Karl Deisseroth, Peter Hegemann and Georg Nagel for discovering light-gated ion channels and creating optogenetics.
- A study published Oct. 7 in the New England Journal of Medicine treated 10 people with advanced retinitis pigmentosa by injecting a gene for ChrimsonR into one eye and giving patients goggles that convert camera images into amber-light patterns.
- Seven of 10 participants increased light sensitivity and six reached predefined, clinically meaningful gains that enabled tasks such as detecting or locating objects and finding a doorway while wearing the goggles.
- Within the trial limits the treatment was judged safe: investigators reported about 33 mostly mild or moderate ocular events and one severe event that resolved within minutes after treatment.
- Researchers say the results show proof of concept but remain limited because patients did not regain reading or face recognition, rehabilitation time improved outcomes, and larger trials plus better vectors and higher-resolution goggles are under way to boost benefit and test other uses.
