Medial transposition of the lateral rectus muscle in combined third and fourth nerve palsy.

Abstract

Surgical treatment of combined third and fourth nerve palsy is a challenging problem in strabismology. Five of the 6 extraocular muscles are paralyzed, which leaves the lateral rectus muscle with no antagonist to counteract its activity and usually results in a maximal exotropia. The goal of surgery is to achieve orthophoria in primary position with limited ductions. Because some believe that a conventional recession-resection procedure will inevitably result in a drift back to exotropia,(1) several other methods have been proposed to treat this disorder. These include temporal mattress suture,(2) eye muscle prosthesis, (3,4) splitting and reattaching the lateral rectus muscle near the vortex veins,(5) and fixation of the eye with fascia lata.(6) Taylor(7) suggested using medial transposition of the lateral rectus muscle in a case of isolated third nerve palsy. We report the outcome of a procedure that included such a transposition for the treatment of combined third and fourth nerve palsy.
