The MRI revealed laceration of the right inferior rectus muscle near the junction of its anterior and middle thirds. 50-year-old man presented with horizontal double vision after being injured by an iron hook. The MRI revealed laceration of the right medial rectus muscle approximately 10 mm from its insertion site. Both muscle ends were brought together during surgery.
