Anomalous insertion of superior oblique and superior rectus muscles in a patient with mirrored hand movements.

Congenital anomalies of extraocular muscles are rare and few cases have been described, most occurring in patients with craniosynostosis and chromosomal abnormalities. However, these anatomical abnormalities of extraocular muscles can occur in healthy individuals and should be suspected especially in cases of atypical strabismus. We report a patient with strabismus and anatomical anomalies involving superior oblique and superior rectus muscles of both eyes associated with mirrored movements of the hands.
