The authors, going through the literature on ophtalmoplegie migraine, point out the difference of opinions concerning its existence or not and its physiopathology. They present two cases. Both had a rich symptomatology characterizing the attacks of migraine (more or less rapid onset of the headache localized to one hemicranium and folowed by neurovegetative signs, vomiting and fotofobia). Both cases showed, in the electroencephalogram, bilateral symetrical paroxysmal dysrhythmia indicating a true migraine in patients without epileptic seizures and without an epileptic familial background. The ophtalmoplegia usually followed the most severe attacks of headache with total involvement of the third pair, lasting one to thirty or more days. Based in these two cases where attacks of migraine (localized cerebral oedema) were followed by repetitive troncular palsy of the ipsilateral third pair, the authors think to be able to adopt Foster-Kennedy's theory (compression of the nervous trunk by the oedematous brain) and to accept the existence of a true ophtalmoplegic form of migraine in the sensus of Charcot.
