Abstract

PURPOSE
Strabismus fixus is a rare form of strabismus which is known for its difficulty to correct surgically, because it tends to go back to its previous state after the surgery. We report the case because we had successfully corrected the case of convergent strabismus fixus. SUBJECTS AND METHODS: A 38-year-old female patient who had both medial rectus muscle tenotomy 10 years before was operated with both lateral rectus muscle resection, superior and inferior rectus muscle recession and temporary traction suture for 5 days, but it was dissatisfactory, so making a hole in the lateral orbital rim was performed by microdrill, with fixation of insertion site of the lateral rectus muscle to the lateral orbital rim by permanent traction suture. RESULTS: At three months after the surgery, patient appeared to be almost orthophoric at primary position. Eye movement was impossible but we had satisfactory result cosmetically. CONCLUSION: It is suggested that eyeball fixation to lateral orbital rim is an effective surgical procedure for the case of convergent strabismus fixus which was not corrected by previous surgical techniques.
