Light, restored in pieces: blind patients detect objects again with gene therapy and smart goggles

Seven of ten blind patients treated with an optogenetic therapy — gene therapy that makes surviving eye cells sensitive to light, paired with special goggles — became more sensitive to light, and six reached a level doctors count as a meaningful improvement. The international team, led from Pittsburgh and Basel, followed the first treated group for years and found the approach safe, offering real hope for people with advanced retinitis pigmentosa, an inherited condition that slowly takes sight away.
