Abstract

Background  Paralysis of the inferior division of the oculomotor nerve is relatively rare. Little has been written about its surgical treatment.

Methods  Five patients with paralysis of the inferior division of the oculomotor nerve were treated with transposition of the superior rectus muscle toward the insertion of the medial rectus muscle, transposition of the lateral rectus muscle toward the insertion of the inferior rectus muscle, and tenotomy of the superior oblique tendon in the affected eye.

Results  All 5 patients had a satisfactory outcome. They were free of diplopia in the primary position as of their last examination. Follow-up ranged from 3 to 10 years after surgery.

Conclusion  Paralysis of the inferior division of the oculomotor nerve can be adequately treated by simultaneous transposition of the superior rectus muscle toward the insertion of the medial rectus muscle, transposition of the lateral rectus muscle toward the insertion of the inferior rectus muscle, and tenotomy of the superior oblique tendon in the affected eye.
