Imaging the inferior oblique using optical coherence tomography.

Abstract

We report the case of a 81–year-old woman who presented for a routine follow-up of her dry age related macular degeneration. Optical coherence tomography (OCT) using Triton OCT (Topcon, Tokyo) showed the presence of a round area behind the sclera , slightly inferior to the macula in her right eye. The morphology and position of this structure suggests this was a transversal cut of the inferior oblique muscle (IOM) close to its ocular insertion in her right eye. Several publications have reported the utility of OCT technology to visualize the anterior insertion of the rectus muscles. However, to the best of our knowledge this is the first publication to report the potential of posterior segment OCT to visualize the insertion oblique muscles in patients with severe chorioretinal atrophy.
