Further Outpatient Care

Although regimens vary among surgeons, regular follow-up visits are necessary to determine if the eyes are well aligned and if fusional abilities are present and stable.


Further Inpatient Care

Surgery for the patient with strabismus usually is performed as an outpatient procedure.



If left untreated, loss of fusion and stereopsis could occur. If the patient freely alternates, the chance of amblyopia is reduced.

Complications associated with surgery include undercorrection and overcorrection and/or residual or new oblique muscle dysfunction.

Postoperative complications include residual A- or V-pattern strabismus, diplopia, and undercorrection or overcorrection of the horizontal deviation.



The prognosis for patients with this condition is good. Only one surgery is required to correct the deviation in 80% to 85% of patients; 10% to 15% of patients may need a second or third procedure for good alignment.

Success for binocularity depends on the patient's age, the time of presentation, and any previous amblyopia. Failure to detect and appropriately treat this condition could result in loss of binocularity and possibly amblyopia

Postoperative drift in patients with comitant exotropia alone and patients with intermittent exotropia with coexistent A or V pattern has been studied, and it has been seen that patients with a coexistent V or A pattern have a reduced risk of postoperative recurrence. [13]
