Abstract: 

Purpose: To determine the effectiveness of anterior transposition of the inferior oblique muscle for treatment of superior oblique palsy in patients with 16-25 PD of hypertropia in primary position.
Material and methods: Twenty patients with unilateral superior oblique palsy, underwent anterior transposition of the inferior oblique muscle. A modification of the surgical technique of Elliott and Nankin was used. The alternate prism cover test measurements were made in all cardinal positions of gaze before and six months after surgery.
Results: Mean reduction of hypertropia after surgery was 18.6 PD in primary position, 24 PD in adduction, 28.5 PD in elevation and adduction, and 20.1 PD in depression and adduction. Postoperative hyperdeviation in primary position was 5 PD or less in 19 patients. There was no hypotropia in primary position. Mild limitation of upgaze was found in 20% of the patients and the same number developed mild fullness of the lower lid.
Conclusion: Anterior transposition of the inferior oblique muscle is very effective in eliminating the hyperdeviation of patients with 16-25 PD hypertropia in primary position due to superior oblique palsy. Its complications are mild and insignificant.
