Scientists have discovered through animal models that children deprived of sight in initial stages of life might only suffer from improper wiring in their brain that is able to be effectively rewired with restoration of vision. Causes of blurred vision (amblyopia) in children include congenital cataracts, which is easily treatable with surgery, allowing immediate return of sight and reparation of neuronal connections in the brain from the affected eye to the visual cortex. The researchers also found that visual acuity was more rapidly restored with the use of both eyes, as opposed to patching the good eye in order to strengthen the recovering eye.
