Surgical Outcome of Inferior Oblique Myectomy versus Recession-Anteriorization in the Treatment of Inferior Oblique Overaction.

These two weakening procedures are effective for treating IOOA. Although IORA seemed slightly superior to IOM in terms of favorable outcomes, the difference was not statistically significant. Moreover, the myectomy procedure was easier, was less time-consuming, had a lower risk of globe perforation and presented fewer complications such as anti-elevation syndrome.
