眼部帯状ヘルペスに合併した動眼神経麻痺の2症例

Oculomotor palsy in two cases of herpes zoster ophthalmicus

（P2-2-18）　72歳男性と67歳女性に，角膜病変を含む眼部帯状ヘルペスが発症し，皮疹出現から約1週後に同側の動眼神経麻痺が生じた。両症例とも，動眼神経麻痺は1〜2か月後に自然寛解した。両症例が受診した過去1年間の眼部帯状ヘルペスの症例は12例であり，動眼神経麻痺の併発はこの2例17％である。眼瞼腫脹による軽度の眼筋麻痺が見過ごされる可能性に留意すべきことが結論される。

Two patients, a 72-year-old male and 67-year-old female, developed herpes zoster ophthalmicus involving the cornea. Ipsilateral oculomotor palsy occurred one week after appearance of the skin lesion. The oculomotor palsy in both cases spontaneously recovered one to two months later. We observed 12 cases of herpes zoster ophthalmicus during the foregoing one year. The incidence of oculomotor palsy was 2 cases (17%) as reported here. These cases show the importance of paying due attention to possible oculomotor palsy complicating herpes zoster ophthalmicus, because ophthalmoplegia may be overlooked by the presence of palpebral edema.
