“…Regarding those changes in the internal carotid artery: Hfrven et al 34 An increased intraocular pressure and indentation pulse, as described by Broch et al, 36 suggested the possibility of dilatation of the ophthalmic or internal carotid arteries. On Ekbom's 35 angiographic study of one patient, dilatation of the ophthalmic artery was indeed noted.…”

“…Ictal CIP amplitudes, NS side, have not been examined systematically. An asymmetry of 15% is reckoned as being abnormal (Hørven et al 1972). Outside attacks, values of 21 my, S side, and 17, NS side, respectively were observed on one occasion: an asymmetry of 24%.…”

Shortlasting, unilateral, neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) syndrome is a rare headache, described by our group in 1989. This overview presents our early studies of SUNCT pathogenesis. Due to the conspicuous ictal, ocular phenomena, ie, conjunctival injection and tearing, our studies started out with ocular parameters: intraocular pressure and corneal indentation pulse amplitudes, both of which showed clear ictal increments, symptomatic side. Beat-to-beat, noninvasive blood pressure measurements during attack showed instant, systolic blood pressure rise and corresponding pulse rate decrease. Carotid body, the principal peripheral chemoreceptor, seemed to function normally. The middle cerebral artery was dilated during attacks, particularly on the symptomatic side. Finally, some viewpoints are added regarding terminology. SUNCT is a workable and accepted term. There does not seem to be any need for another, fictitious term to describe the same clinical picture.

It has been known for many years that there is a Horner-like picture on the symptomatic side in many cases of cluster headache (1, 2). The corneal indentation pulse (CIP) amplitudes and the intraocular pressure (IOP) increase markedly during attacks, the increase being most pronounced on the symptomatic side (3, 4). As far as we know at present, these changes occur in all cases, provided the attack is pronounced enough. CIP amplitudes and lOP were the first cluster headache parameters which were demonstrated to show attack-related changes without exception. The corneal temperature also increases on the symptomatic side during attacks (4). Interictally, there may be "cold spots" supraorbitally on the symptomatic side as demonstrated by thermography (5), and they frequently transform into warmer areas during attacks (6). How studies provide contradictory results, but recent investigations (Doppler studies) tend to show that blood flow velocity is increased in the symptomatic area during attacks (7). Recently, nasal secretion and lacrimation have been quantified and have been found to increase bilaterally during attacks, although mostly to the largest extent on the symptomatic side (8, 9). All these features are presumably reflections of an autonomic disorder which is most pronounced on the symptomatic side.What do these "autonomic" disturbances imply as far as the underlying mechanism is concerned?
