Anomalous medial rectus muscle insertion in a child with craniosynostosis

Abstract

Introduction: Oblique and vertical rectus muscle anomalies have been commonly reported in patients with craniofacial syndromes, while horizontal rectus muscle anomalies have been uncommonly reported.

Methods: Case report of a child with Crouzon's Syndrome who was found to have an anomalous medial rectus muscle insertion at surgery.

Results: A bifid left medial rectus muscle insertion was found at surgery, requiring a small modification of the planned surgical procedure.

Conclusion: Anomalies of extraocular muscles may be present in patients with craniofacial syndromes and strabismus surgeons should be prepared to modify their surgical plan when anomalous extraocular muscles are found.
