Follow-up

Further Outpatient Care

  • Strabismus surgery is performed as an outpatient procedure.
  • Although regimens vary among surgeons, regular follow-up visits are necessary to assess eye alignment and to examine fusional abilities.

Complications

  • If left untreated, intermittent deviations could progress to constant exodeviations, with subsequent development of amblyopia and loss of fusional abilities in young children.
  • No specific complications are related to surgery for this condition; however, complications of eye muscle surgery in general apply.
  • Postoperative complications include overcorrection, undercorrection, residual A- or V-pattern strabismus, and diplopia in side gazes due to lateral incomitances.

Prognosis

  • Some factors that affect the prognosis are as follows:
    • Some authors believe that surgical alignment before age 4 years yields better results with lower risks for amblyopia. On the other hand, even a slight overcorrection increases the risk of loss of bifoveal fixation at this young age.
    • Patients with better fusional control preoperatively do better postoperatively.
    • Correction of refractive error should be continued postoperatively.
    • Tenacious proximal fusion may predict better postoperative results.
  • Both motor alignment and sensory functional improvement should be included in the postoperative assessment of response to surgery.

Miscellaneous

Medicolegal Pitfalls

  • Failure to detect and promptly treat intermittent exotropia could result in constant exotropia with loss of binocularity and possible amblyopia
  • Failure to assess the neurologic condition in patients with exotropia associated with a neurologic disorder and to refer those patients for neurologic evaluation
