An ophthalmoplegic migraine means

Ophthalmoplegic migraine is characterized by recurrent attacks of ophthalmoplegia, following severe migrainous headaches. The condition almost always begins in childhood, and is considered to be rare in adults. However, OM may occur for the first time in adult life. The typical clinical picture of OM includes a child with severe migraine that lasts for several days and is followed soon after, by ptosis and diplopia due to isolated oculomotor nerve palsy, as the headache remits. Pupillary involvement with a 'full blown' pupil is the rule in children.However, pupillary sparing is not uncommon, especially in adults. Abducens nerve involvement is uncommon and trochlear nerve palsy is rare. Recovery is the rule. Rarely, deficits persist after multiple attacks. ref - pubmed.com
