Scientists restore key parts of vision in blind mice for first time

For the first time, scientists have been able to restore key parts of vision in mice blinded by loss of nerve connections between the eye and the brain. The achievement is a significant step forward in finding ways to restore or improve sight in people with glaucoma and eye injuries that affect the optic nerve. The researchers coaxed optic-nerve cables that carry vision information from cells in the retina at the back of the eye – along the optic nerve and beyond – to regenerate and retrace their routes to various parts of the brain. In Nature Neuroscience, a team led by senior author Andrew Huberman, an associate professor of neurobiology who heads a neural vision lab at Stanford University School of Medicine in California, reports unprecedented success in restoring…
