Abstract
IntroductionThe surgical correction of anomalous movement such as upshoot in Duane syndrome is challenging. Lateral rectus muscle disinsertion and reattachment to the lateral orbital wall is a new approach used to minimize or eliminate the effects of co-contraction including globe retraction, palpebral fissure narrowing and anomalous vertical movement.Case presentationWe report a case of a 7-year-old boy who underwent this procedure for severe upshoot, globe retraction and exotropia in the left eye due to Duane syndrome. The patient achieved satisfactory ocular alignment following surgery. Upshoot and globe retraction were substantially improved.ConclusionLateral rectus muscle disinsertion and reattachment to the lateral orbital wall is a safe and effective procedure for weakening of the anomalous lateral rectus muscle in Exotropic Duane Syndrome.
Highlights
The surgical correction of anomalous movement such as upshoot in Duane syndrome is challenging
Various surgical approaches have been described for the treatment of upshoot and downshoot in Duane syndrome including recession of the lateral and medial rectus muscle, Y splitting of the lateral rectus muscle at the insertion, and posterior fixation suture of the horizontal rectus muscles [3]
We report a case of a patient with unilateral Duane syndrome with exotropia who underwent this procedure for correction of severe upshoot and globe retraction
Summary
The surgical correction of anomalous movement such as upshoot in Duane syndrome is challenging. Conclusion: Lateral rectus muscle disinsertion and reattachment to the lateral orbital wall is a safe and effective procedure for weakening of the anomalous lateral rectus muscle in Exotropic Duane Syndrome. Duane syndrome is an ocular motility disorder characterized by anomalous innervation of the lateral rectus muscle [1].
