Exotropia

Exotropia

Exotropia is a variety of heterotropia in which there is manifest outward turning of the visual axis of an eye; the term is synonymous with divergent strabismus. It may be demonstrated using the cover test as an inward movement of the eye which is forced to assume fixation by occlusion of the other eye.
When the medial rectus muscle is paralyzed, the eyes are exotropic (wall-eyed) on attempted lateral gaze toward the paralyzed side, and the images are crossed.
