Disease[edit | edit source] Exotropia is a type of eye misalignment, where one eye deviates outward. The deviation may be constant or intermittent, and the deviating eye may always be one eye or may alternate between the two eyes.
Intermittent exotropia is a fairly common condition. Sensory exotropia occurs in the presence of poor vision. Infantile exotropia (sometimes called congenital exotropia) is seen during the first year of life, and is less common than essential exotropia which usually becomes apparent several years later.
