Anterior and nasal transposition of inferior oblique muscle

Abstract

We report the case of a 20-year-old woman who presented with residual esotropia, dissociated vertical deviation (DVD), and inferior oblique over-action (IOOA) who underwent horizontal rectus muscle surgery and anterior and nasal transposition of the inferior oblique muscle. Postoperatively, she was orthotropic and showed resolution of DVD and IOOA providing an excellent motor outcome.
