自然に吸収された水晶体銅症の1例

Spontaneously disappeared chalcosis lentis; Report of an unusual case

　銅及びその化合物（真鍮，雷管等）は眼内異物中鉄片に次いで頻度が高く，而も眼内異物のうちで最も刺激が強く，又無菌的に入つた場合でも急激な化膿性炎症を起し，一般に予後は不良である。然し異物の大きさ，飛入部位，その他の条件により予後の良好な例も報告されている。

　私共も最近眼球銅症の1例に遭遇したが，その経過観察中に水晶体銅症が自然消失した極めて興味ある症例である故ここに報告する。

Pieces of brass flew into the eyeballs of a 13-year-olb-boy by explosion of gunpowder in the brass tube.

Traumatic cataract was observed in the right eye, while there appeared the findings of chalcosis bulbi in the left eye: Three mon-ths after the injury greenish opacity of the lens was observed. The lens got turbid totally excepting central pupillary area. Slit-lamp examination revealed the deposit of pigment beneath the anterior and posterior lens capsu-les.

A lot of minute metallic sheen were seen in the macular region.

26 months' after the injury the opacity of the lens has almost disappeared.
