Surgical outcomes of medial rectus plication for management of basic type intermittent exotropia

Abstract

Intermittent exotropia is an exodeviation intermittently controlled by fusional mechanisms, due to the instinctive drive for binocular vision. Intermittent exotropia spontaneously breaks down into a manifest exotropia. Intermittent exotropia is the commonest type of exodeviation and often first observed by parents in early childhood as a spontaneous drifting out of one eye mostly when the child is tired, sick or daydreaming. Adult patients may manifest the deviation after alcohol or sedative intake.
