ヘルペス性輪部血管炎と考えられる2症例

Two cases of presumed herpetic limbal vasculitis

　ヘルペス性輪部血管炎（Herpetic limbalvasculitis）と考えられる症例を2例（症例1：21歳女性，症例2：22歳女性）経験した。両症例とも片眼の輪部結膜に局所性に毛様充血を認め，その毛様充血に沿った周辺部角膜に浮腫を認めた。症例1は1か月前に樹枝状角膜炎に罹患しており，病巣擦過により，単純ヘルペスウイルス1型（HSV−1）を同定した。症例2は壊死性角膜炎の既往を有し，角膜知覚の低下がみられた。症例1は，trifluorothimidine，抗生剤点眼，症例2はacyclovir眼軟膏，抗生剤点眼にて治癒した。

We observed 2 females, aged 21 and 22 years each, with presumed herpetic limbal vasculitis. Both cases were characterized by localized ciliary injection, corneal stromal edema in areas adjacent to the injection, and unilateral involvement. One patient had developed dendritic keratitis 1 monthbefore. Herpes simplex virus type 1 was identified from the sample obtained by debridement. In the other patient, there was a history of necrotizing keratitis and loss of corneal sensation. The corneal lesion healed by topical trifluorothimidine and antibiotics in one case and by topical acyclovir and antibiotics in the other.
