Consecutive exotropia following strabismus surgery

We investigated the clinical factors affecting the development of consecutive exotropia following surgery. The development period of consecutive exotropia, amblyopia and medial rectus functional insufficiency were evaluated in eighty-nine patients with primary esotropia that changed to consecutive exotropia after surgery. In the presence of deep amblyopia consecutive exotropia developed earlier and when two horizontal muscles were operated medial rectus functional insufficiency was more frequent in symmetrical rather than asymmetrical surgical procedure. Since consecutive exotropia may develop many years after esotropia surgery a long-term follow-up period in patients without consecutive exotropia in the early postoperative period is advised.
