Abstract : Finding an alternative to ipsilateral medial rectus recession when performing superior and inferior rectus transposition surgery; thus eliminating the risk of anterior segment ischemia and overcorrection. Fourteen patients with sixth nerve palsy of more than 8 months duration were included in the study. Ages ranged between 6- to 76-years-old. All the patients underwent full tendon transposition of the Superior and Inferior rectus muscles to the lateral rectus muscle insertion and injection of the ipsilateral medial rectus muscle with botulinum toxin. Two patients had a significant esotropia (more than 8 prisms) and were advised to have a recession surgery for the ipsilateral medial rectus. Six patients had a non significant esotropia, 4 patients were ortho and 2 were exotropic (less than 12 prisms). Transposition procedures are the best option for treating abducens nerve palsy and almost always require an ipsilateral medial rectus recession, thus rendering some patients at risk for developing anterior segment ischemia. The results of this study are encouraging; injecting the medial rectus muscle with botulinum toxin at the time of surgery can replace the need to recess the muscle and reduces the risk of anterior segment ischemia. The author hopes this study will encourage others to consider this procedure
