Antielevation syndrome with onset of diplopia 10 years after inferior oblique anterior transposition

Abstract

Antielevation syndrome as a complication of inferior oblique anterior transposition usually appears in the early postoperative period. A 29-year-old woman who had been operated on for right superior oblique palsy developed diplopia 10 years after surgery: motility examination was consistent with an antielevation syndrome. A right inferior oblique recession of 14 mm was performed on the previously transposed muscle; motility improved, and the patient has remained asymptomatic.
