Strabismus (crossed or eye turn) occurs when both eyes are unable to properly team and align together. There are many types of strabismus: esotropia (eyes turn inward), exotropia (eyes turn outward), hypertropia (eye turn upward) and other varying combinations. It occurs in roughly 2-4% of the population. In about one-half of those who have strabismus also have amblyopia or the inability to appreciate clarity through the eye in absence of pathology.
Due to the constant or intermittent misalignment it can lead to reduced or failed ability to appreciate 3D vision or depth perception. This can lead to difficulties with hand eye coordination, eye movement control and movement through space.

In office vision therapy provides diagnostic and non-surgical treatment to visual deficient associated with strabismus. Due to the success of therapy for strabismus, surgery should be treated as a last resort option. If surgery is ultimately required undergoing vision therapy pre-surgical and post-surgical can improve outcome results.
