Fuchs虹彩異色虹彩毛様体炎の臨床像

Clinical features of Fuchs heterochromic iridocyclitis

　1999年までの10年間に自検したFuchs虹彩異色虹彩毛様体炎患者34例の臨床像をまとめた。男性16例，女性18例で，初診時年齢は平均35.3歳，全例が片眼性であった。角膜後面沈着物と虹彩萎縮が全例にあった。白内障は25眼（74％）にあり，従来の日本で報告された頻度よりも少なく，21眼では後嚢下白内障であった。軽度の漿液性虹彩炎が33眼（97％）にあり，虹彩結節が15眼（44％），隅角新生血管が4眼にあった。検索できた32眼では硝子体混濁が27眼（84％）にあった。初診時視力は34眼中17眼が1.0以上，3眼が0.1以下であり，視力不良の原因はほとんどが白内障であった。白内障手術を行った8眼の成績は良好であった。

We reviewed the clinical features in 34 patients with Fuchs heterochromic iridocyclitis seen from 1990 through 1999. The series comprised 16 males and 18 females. The ages averaged 35.3 years. All were unilaterally involved. All the affected eyes showed keratic precipitates and iris atrophy. Cataract was present in 25 eyes (74%), of which 21 eyes had posterior subcortical cataract. This incidence of cataract was lower than previously reported in Japan. Mild serous iritis was present in 33 eyes (97%), iris nodules in 15 eyes (44%) and rubeosis in the chamber angle in 4 eyes. Vitreous opacity was present in 27 of 32 examined eyes (84%). Visual acuity was 1.0 or more in 17 eyes and 0.1 or less in 3 eyes. Poor visual acuity was mainly due to cataract. Cataract surgery in 8 eyes resulted in favorable outcome.
