[Delayed extraction of an intraocular foreign body].

The authors describe two cases of siderosis of the bulbus which developed as a consequence of late diagnosis of intraocular foreign bodies. The character of siderosis differed, however, in the two patients. In the first patient the picture of generalized siderosis confirmed also by electroretinographic examination permitted the assumption of an adverse course of the disease already on admission, as was confirmed by the progression of the disease even after removal of the intraocular foreign body. In the second patient probable encapsulation of the foreign body led to focal siderosis and a favourable course of the disease.
