    Abstract:
    Visual disorders are an important symptom in the migraine of developing age. Different kinds of visual disturbances can precede, accompany or follow a migraine attack. These visual disturbances can be grouped into negative (hemianopsia, quadrantopsia, scotoma) and positive (phosphene, teicopsia, metamorphopsia, macropsia, micropsia, teleopsia, diplopia, dischromatopsia, hallucination disturbances) disorders. The pathogenetic mechanism of the visual phenomena of migraine has not yet been clarified. Various hypotheses have been proposed: vasospasm with consequent ischemia of some cerebral areas, the opening of arteriovenous shunts between the intra and extra cerebral circulation, the formation of microthrombi in arterioles and dopaminergic hypersensitivity of some nervous centers. We have studied 1787 children, affected by migraine with (13%) or without (87%) aura. Among the patients, 211 (12%) referred visual disorders, especially scotoma and phosphene. These data let us hypothesize that a relationship between migraine and visual disorders is present also in pediatric age. However this relationship is less important than in adults.
