Temporary incyclotorsion following surgical correction of bilateral superior oblique palsy

J AAPOS 11(1):3 (2007) PMID 17126051

We report three patients with acquired bilateral superior oblique paresis who had bilateral modified Harada-Ito procedures, which resulted in significant incyclotorsion (ranging from 6^o to 19^o) on the first day postoperatively. For Case 1 this was the only procedure, while Cases 2 and 3 also underwent simultaneous bilateral inferior oblique weakening. This overcorrection decreased spontaneously over the following 8 months to leave all patients asymptomatic. One patient returned 8 years following the initial surgery with symptoms of diplopia and recurrence of excyclotorsion.
