Abstract

PURPOSE
The purpose of this paper is to study the efficacy of inferior oblique weakening procedures in the surgical treatment of congenital unilateral superior oblique palsies. METHODS: We compared the preoperative and postoperative vertical deviation by a retrospective chart review of 45 patients who had undergone inferior oblique weakening procedures in unilateral congenital superior oblique palsies with at least 6 months of postoperative follow-up. Classifications of final postoperative vertical deviation were excellent (under 3 prism diopters, PD), good (4-7PD) and poor (over 8PD). RESULTS: Thirty-one (68.9%) of the 45 patients had excellent results. Average preoperative vertical deviation was 14.4 PD and average postoperative vertical deviation was 3.6 PD., giving an average reduction of vertical deviation of 10.8 PD. Preoperative head tilting was seen in 38 cases (84.4%) and improvement was seen in 32 cases (84.2%) postoperatively. CONCLUSIONS: The inferior oblique weakening procedures are an effective tool in the treatment of unilateral congenital superior oblique palsies, especially in patients with inferior oblique overaction.
