虹彩炎，ドルーゼ，および網膜血管炎を特徴とする若年性ぶどう膜炎の2例

Juvenile uveitis characterized by recurrent iritis, secondary drusen and retinal vasculitis

　次のような共通点を持つ，原因不明のぶどう膜炎の2症例を報告した。

　①若い女性である。②両側性の軽度の虹彩炎が遷延する。③軽度の網膜血管炎を伴う。④網膜色素上皮レベルに，黄灰白色の点状あるいはその融合した斑状病変が，黄斑部外の主として赤道部に集族・散在し，それらは，螢光眼底撮影において，pigment epithelialwindow defectを示す。臨床的には，drusenと同一のものとみなされる。⑤下肢の関節炎の既往がみられ，1例は，sero-negative spondyloarthritisと診断された。⑥霧視が唯一の症状であり，視力は良好である。

Two females, aged 15 and 17 years each, develop-ed uveitis of unknown etiology with some distinct clinical features. The condition occurred as bilate-ral recurrent mild iritis associated with retinal flecks and peripheral retinal vasculitis. The flecks were yellowish-gray in color, punctate, sharply defined, and were located in the pigment epithelial layer. Some were irregularly confluent. They were dis-tributed mainly in the equatorial region and were absent in the macula. On fluorescein angiography, they appeared as hyperfluorescent spots showing pigment epithelial window defect.
