The oculocardiac reflex may mimic signs of intracranial hypertension in patients with combined cerebral and ocular trauma

Neurocrit Care. 2012 Feb;16(1):151-3. doi: 10.1007/s12028-011-9560-5.

Abstract

Background: In the setting of head trauma, progressive bradycardia may raise suspicion for intracranial hypertension, especially when accompanied by pupillary abnormalities or systemic hypertension.

Methods: We describe the case of a patient with concomitant cerebral and ocular trauma who presented with a fixed and dilated pupil and progressive bradycardia due to an oculocardiac reflex.

Results: The oculocardiac reflex is an unusual cause of bradycardia due to stimulation of the ophthalmic division of the trigeminal nerve and has been described in a variety of clinical settings.

Conclusions: Clinicians should be aware that the oculocardiac reflex might mimic signs of intracranial hypertension in patients with combined facial and cerebral trauma.
