Abstract
The amount of hypertropic correction obtained with a unilateral inferior oblique recession procedure has been much debated in the literature. The surgical results of 32 patients following unilateral inferior oblique recession are reviewed. Four patients (12%) demonstrated masked bilateral superior oblique palsy. In the remaining 28 patients, the amount of preoperative inferior oblique overaction was directly correlated to the amount of hypertropia in contralateral gaze. Eighty-six percent of patients had an excellent surgical result. The procedure appeared to grade itself for the amount of hypertropia correction needed. However, patients with larger amounts of hypertropia and significant hypertropia in ipsilateral gaze may require a two muscle procedure.
