特異な異常連合運動を示した外傷性両側動眼神経麻痺

Aberrant regeneration following bilateral traumatic oculomotor palsy

　外傷による両側動眼神経麻痺の症例を紹介し，その責任病巣として硬膜貫通部が推定された。また経過中に出現した異常連合運動中眼球運動にともなって散瞳を呈した事より，動眼神経と交感神経の間の異常神経支配の可能性が示唆された。

A 62-year-old female developed typical features of bilateral oculomotor palsy following blunt head trauma in a traffic accident.The oculomotor nerves were apparently injured at the edge of the ten-rorium cerebelli.

Spontaneous recovery of the oculomotor palsy began 2 months after the injury and showed signs of aberrant nerve regeneration. There occurred widening of the palpebral fissure on attempted ad-duction and depression. Mydriasis occurred during adduction and attempted elevation and depression.
