Spontaneous extrusion of intraocular foreign body after 11 years.

A case of spontaneous extrusion of intraocular foreign body after 11 years is presented. Despite being magnetic and containing mostly iron the foreign body could not be removed in repeated magnet trials. It was retained in the ciliary body region for a very long time without causing siderosis. The foreign body was spontaneously extruded without any signs of intraocular inflammation.
