ABSTRACT

ABSTRACT: Purpose: To evaluate the outcome of surgical treatment of superior oblique palsy. Material and methods: 43 superior oblique palsy(SOP) patients who had undergone surgical treatment between 1992-2003 were analysed retrospectively. In 22 cases (Group I), inferior oblique weakening, in 19 cases (Group II), superior oblique(SO) strengthening and inferior oblique(IO) weakening, in 2 cases (Group III) vertical rectus weakening operations were performed. The mean post-operative follow up period was 12.9 8.5 months. We used Wilcoxon Signed Ranks tests for statistical evaluations. Results: Abnormal head position had been improved in 93% of patients after the operation. There are statistically significant difference between preoperative near and distance vertical deviations and postoperative near and distance vertical deviations for Group I, Group II (p 0.001, p 0.001, p 0.001, p 0.001). There are significant improvement IO hiperfunction and SO hypofunction (p 0.05, p 0.05). Conclusion: It is concluded that in treatment of SOP, IO weakening procedure had enough effect in small vertical deviation and SO strengthening had a important effect in the patients who had large vertical deviation.
