Latent Dysautonomic Pupillary Lateralization in Cluster Headache. A Pupillometric Study

Abstract: Forty-five patients with cluster headache in the asymptomatic phase were studied by electronic pupillography, testing autonomic function of both pupils pharmacologically. Topical sympathetically-acting mydriatics, tyramine and cocaine and the cholinoceptor blocker, homatropine, induced defective mydriatic responses on the symptomatic side, indicating latent impairment of sympathetic function. The abnormality was found in interattack intervals of the cluster period or during intercluster phases. The tyramine te… Show more

“…a red, tearing eye, a small pupil and a stuffed nostril with rhinorrhea on the symptomatic side (Lance and Anthony, 1971;Sjaastad, 1992). There is some evidence indicating that dysfunction of the cephalic sympathetic nervous system may be primarily involved in the pathogenesis of CH (Fanciullacci et al, 1982;Salvesen et al, 1987a). However, these results which are preferentially based on studies of the pupillary response to various pharmacological agents, are somewhat conflicting.…”

“…While cranial vegetative symptoms of cluster headache seem to be related to an orthosympathetic hypofunction, often persisting during the silent period [9,10], our knowledge of the systemic vegetative system is still poor and results are often controversial. There are several reasons for this: (1) studies are carried out using different tests and in different periods (i.e., during attack, outside attack but within an active phase, outside the active period); (2) there is no standardised method as regards the study of the autonomic nervous system and it has been explored neurophysiologically, pharmacologically or by means of other techniques [7]; and (3) obtained values are often poorly comparable, as they are frequently influenced by internal and external factors (temperature, drugs, smoke, psychic conditions of the patient).…”

“…With a battery of sympathetically acting eye drops, the pupillary impairment of sympathetic neuronal activity was demonstrated. Tyramine eye drops in CH patients induced an anisocoric pattern characterised by the pupil on the symptomatic side being smaller than the other pupil [9,10]. Asymmetric mydriatic response to the noradrenaline releaser tyra-mine was proposed as an objective diagnostic test for cluster patients.…”
