Exotropia that occurs after a period of esotropia is called consecutive exotropia. Rarely, exotropia may develop spontaneously in a patient who was previously esotropic and never underwent strabismus surgery. Much more commonly, consecutive exotropia develops after previous surgery for esotropia (postsurgical exotropia), usually within a few months or years after the initial surgery. However, in some patients who had surgery for infantile esotropia, consecutive exotropia may not develop until adulthood. Consecutive exotropia may be intermittent or constant.
