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.
