Purpose:
To evaluate the surgical results of correcting strabismus with inferior oblique hyperfunction.
Material And Methods:
A retrospective chart review of 40 patients, who underwent surgery from 1999-2001 was performed. 7 patients had isolated inferior oblique hyperfunction, 5 with hypertropia, 23 patients had esotropia with inferior oblique hyperfunction and 5 patients had exotropia with inferior oblique hyperfunction. The recession of inferior oblique muscle was undergone in cases with inferior oblique hyperfunction, sometimes in hypertropia with anteposito. The recession-resection of rectus muscles with myotomy-tenotomy of inferior oblique muscle or his recession usually were performed in cases with coexisting esotropia or exotropia.
Results:
In all cases eyes were acceptably aligned. The recession of inferior oblique muscle is the most effective method of operation in high oblique hyperfunction.
