title: Idiopathic ocular neuromyotonia: a neurovascular compression syndrome?
abstract: Ocular neuromyotonia in the muscles innervated by the right oculomotor nerve was diagnosed in a patient without a history of radiation therapy. Electromyography of the levator palpebrae showed continuous motor unit activity. Brain MRI disclosed a close contact between the right third cranial nerve and a basilar artery dolichoectasia. The patient partly benefited from carbamazepine therapy. This unique finding suggests that neurovascular compression syndrome could be an hitherto unrecognised cause of ocular neuromyotonia.
