Quick Reference

A variant of migraine more common in men than in women (ratio 9:1). The unilateral pain around one eye is very severe and lasts between 15 minutes and three hours. The attacks commonly occur in the early hours of the morning but may occur up to eight times a day. The pain is associated with drooping of the eyelid (ptosis), a bloodshot eye, a small pupil, and/or excessive production of tears in the eye. The acute treatment is with antimigraine drugs (5HT1 agonists) and prophylaxis is with such drugs as verapamil, lithium, or methysergide.
