Strabismus ("struh-BIZ-mus") is a misalignment of the eyes in which both eyes are oriented in different directions.
What causes strabismus?
Sometimes called “crossed-eyes” or “walleye,” strabismus often begins when a child is very young and is usually the result of a problem with neuromuscular, including brain, control of eye movement, or less often, the actual eye muscle.
