Examination of the pupils and reflex horizontal eye movements (i.e., vestibulo-ocular reflex and oculocephalic reflex) in the Emergency Department will aid in determining the location of the lesion responsible for the comatose state to either the brainstem, the hemispheres, or both.1,2 When more information is available, a neurologic exam including reflex eye movements can aid in determining the prognosis of patients in a nontraumatic coma including patients successfully resuscitated from cardiac arrest.3This testing is considered to be part of a thorough and complete neurologic examination in the comatose patient.
