An Overview for Concomitant Exotropia Management: Review Article

Abstract

Background: A common type of strabismus known as concomitant exotropia (XT) occurs when mismatched eyes deviate outward and the angle of deviation is the same regardless of which eye is fixed. Among ophthalmologists, there is no agreement on non-surgical treatment options for XT. For those who suffer from strabismus, surgery is an option for correcting their visual axis and restoring their ability to see in both eyes simultaneously. Instead, then severing the muscle, muscle plication involves folding the muscle around itself and stitching it in place, essentially shortening and tightening the muscle. Muscle plication has been found to reduce the risk of anterior segment ischemia by protecting the anterior ciliary arteries. Objective: To hallmark the new guidelines options of concomitant exotropia management. Conclusion: Muscle-tightening techniques such as excision, plication, advancement, and transposition have been documented in the literature. Technical simplicity, the ability to reverse it, shorter operating times, reduced surgical trauma, and the preservation of anterior ciliary arteries are only a few of the many advantages of plication.
