Binocular Treatment of Lazy Eye (Amblyopia)

Amblyopia, a developmental disorder of the visual system that results in information from one eye being ignored by the brain, is currently untreatable in adults. Since amblyopia involves visual loss in one eye, one of the primary deficits is deficient cooperation between the two eyes, which is caused by suppression of the input from the amblyopic eye by the input from the normal eye. Misalignment of the eyes (strabismus) is a common cause of amblyopia. Corrective surgery in strabismus improves motor binocular fusion and improves vision in children; however, this effect is modest in adults.
