Surgical Correction of Convergent Strabismus Fixus

Abstract

Convergent strabismus fixus is a rare condition in which one or both eyes are anchored in a position of extreme adduction. The involved eye is fixed in this position and cannot be moved, and the forced duction test will confirm the immobility of the eye. This condition generally is thought to be congenital and caused by fibrosis and loss of elasticity of the medial rectus muscle. However Villaseca postulated that fibrosis of the medial rectus muscle is the consequence of contracture following a lateral rectus paralysis rather than a primary anomaly. The authors experienced two cases of monocular convergent strabismus fixus of left eye in a 51 year old female patient and a 63 year old male patient. In the latter case, we performed complete disinsertion of medial rectus muscle combined with recession of conjunctiva and Tenon's capsule and temporary fixation of the globes with traction sutures in a position of abduction on left eye. The result of that surgery, however, was not satisfactory. So we performed 11mm resection of lateral rectus muscle of left eye about 8 weeks after the first surgery and followed up for months in satisfactory result.
