[The operation time and post-operative target eye alignment of intermittent exotropia].

Different from other types of strabismus, children with intermittent exotropia can maintain normal eye alignment and binocular vision in a long period of time. But the course of intermittent exotropia is mostly progressive, the eye position may drift outward even after surgery, so there is a certain risk of recurrence or under correction. These features often lead confusion to the clinicians in determining the operation time and postoperative target eye position. So how to choose the appropriate intervention time and target eye alignment is a challenge for clinicians. In this paper, we will combine the research status and clinical practice, discuss these issues, and present some point of view for the peer reference.
