Vegetative imbalance in migraine. A dynamic TV pupillometric evaluation.
In this study we investigated the variations of pupillary diameter obtained in different experimental conditions (dark/light adaptation, light reflex, sural nerve stimulation) in a group of migraine patients with unilateral location of pain in almost all the attacks and in healthy controls by means of a TV pupillometric device. The data obtained seems to document the existence in migraine of unbalanced vegetative function ascribable either to a strong sympathetic activity or to a parasympathetic deficiency. Moreover, an involvement of central integrative pathways regulating pupil functioning cannot be excluded.
