Oculocardiac Reflex as a Late Presentation of Orbital Floor Fracture

Delayed repair of orbital trapdoor fractures can jeopardize the viability of entrapped contents and prolong recovery. Variation in presentations, both clinically and radiographically, complicate prompt diagnosis. The oculocardiac reflex may be the only indication of fracture with entrapped orbital contents, but, unfortunately, the reflex has variable onset patterns and can mimic common diagnoses. Therefore, the authors present the case of a 14-year-old male with a right orbital floor fracture, who presented with delayed symptoms secondary to an oculocardiac reflex. The vagal sequelae of the reflex, including gastric hyperactivity and headache, were experienced approximately 1 week after the injury and caused the patient to be misdiagnosed with gastroenteritis and status migrainosus, on 2 separate hospital visits. After admission to the hospital due to progressive symptoms, a CT scan showed concerns for a subacute orbital blowout fracture. The patient underwent orbital floor exploration with findings of scarred orbital fat herniating into a healing fracture site. Repositioning of the fat into the orbit resulted in immediate resolution of the patient's symptoms. Awareness of the presenting characteristics of the oculocardiac reflex can lead to prompt diagnosis and maximize clinical outcomes. Address correspondence and reprint requests to Renata S.
