SCIENTISTS FIND A WAY TO 'REBOOT' VISION IN ADULTS WITH LAZY EYE

Summary from the TLDR newsletter

Lazy eye, or amblyopia, can occur when one eye is deprived of vision early in life. The lack of input disrupts synapse formation in the brain's primary visual cortex, weakening vision in that eye. A new mouse study has found that briefly and reversibly anesthetizing the retina of an amblyopic eye for just a few days can restore the brain's visual responses to that eye. While it is clear that the treatment seems to reset the way the brain engages with specific neurons, scientists still haven't figured out exactly why this is happening.
