Description: A child with amblyopia is sending unequal signals from each eye to the brain. As shown in this animation, neuro-electrical signals travel along pathways from the eye to the brain. The unaffected right eye is sending strong signals. The eye with amblyopia, the left eye, is sending fewer neuro-electrical signals. If untreated, the pathways through which these signals travel may weaken and not develop properly, damaging the child’s vision.
Placing a patch over the unaffected eye for several weeks will stimulate and strengthen the signals from the eye with amblyopia leading to more normal nerve function in the brain, which improves vision in that eye.
