Ophthalmoplegic migraine is a rare presentation of migraine complicated by an isolated oculomotor paresis. Vasodilation of extracranial vessels is believed to underlie the headache, and vasoconstriction to account for the ophthalmoplegia. Whether the vascular insult involves the central or peripheral portions of the oculomotor nerve is still uncertain. We describe a child who presented with ophthalmoplegic migraine and was demonstrated to have a deficiency of the near triad documented by eye movement and pupillary recordings. Voluntary conjugate eye movements—saccades, smooth pursuit, and optokinetic nystagmus—were normal. Vergence amplitudes appropriate to fixation distance were elicited for Snellen optotypes but not to a point source of light. Concurrent measures of pupillary diameter failed to reveal significant modulation to either stimulus. Brain magnetic resonance imaging scan was normal, and there was no contrast enhancement of the oculomotor nerve at its exit from the midbrain. Both the oculomotor paresis and concurrent presence of a deficiency of the near triad localized the vascular insult to the oculomotor nerve complex in the brainstem.
