Case ReportsOculocardiac reflex associated with a large orbital floor fracture.
A 40-year-old man presented with bradycardia, left eye pain, and intermittent nausea 1 day after blunt trauma to the left orbit. Imaging revealed a large orbital floor fracture with significant herniation of orbital contents but no obvious extraocualar muscle entrapment. ⋯ His bradycardia resolved immediately postoperatively. This case is a unique presentation of the oculocardiac reflex in a large orbital floor fracture with significant herniation of orbital contents but without extraocualar muscle entrapment.

Trapdoor fractures occur almost exclusively in the pediatric population. The authors describe an adult with an entrapped inferior rectus muscle sheath in a trapdoor fracture. A 37-year-old man presented with persistent diplopia 3 weeks after blunt right orbital trauma. ⋯ One month postoperatively, extraocular motility had improved with no diplopia in primary or reading positions. This case demonstrates that trapdoor fractures can occur in adults and should be considered when suggestive findings are encountered. Clinicians should be aware of this because timely diagnosis and treatment might achieve more favorable outcomes.
