[Siderosis bulbi et lentis produced by intralenticular rust (author's transl)].

A 17-year-old apprentice affected with siderosis bulbi and lentis of his right eye, was examined by biomicroscopy, ultrasonography and x-rays without evidence of an i.o. foreign body. After extraction of the cataractous lens all signs of siderosis disappeared within six weeks. The histologic examination of the lens showed a small particle of subcapsular rust.
