Goggles and a gene injection give some retinitis pigmentosa patients limited object detection
Four of eight patients tested consistently detected a notebook through optogenetic goggles after one gene injection, a 10-person NEJM trial reports. The therapy targets surviving ganglion cells, so it need not match any of 100-plus disease genes, but ScienceAlert's account does not break results out by gene.

Optogenetic gene therapy was safe in 10 blind people with advanced retinitis pigmentosa, six of whom gained clinically meaningful light sensitivity. The gains were measured within each patient in a small dose-escalation study, so the result supports safety and shows the approach works in people while sharp vision stays years away.

Optogenetic gene therapy restored some vision to people blinded by retinitis pigmentosa in a small NEJM trial. Seven of 10 participants improved in light sensitivity, Science News reported, though the goggle-aided sight let none of them read words or see faces.

An Aarhus-led team reports that injectable photocatalytic nanoparticles gave surviving retinal neurons in blind mice a light input, enough for visual cortex activity and a behavioural change, with the cells left genetically untouched.

A blind mouse's visual cortex responds to light after an injection of carbon nitride particles
An Aarhus-led team injected 300-nanometre semiconductor particles into mice with advanced retinitis pigmentosa and recorded light-driven activity in the visual cortex, a route to restoring light sensitivity that does not depend on the patient's mutation.
