Intraocular Foreign Bodies
Retained intraocular foreign bodies may produce chronic intraocular inflammation as the result of mechanical, chemical, toxic, or inflammatory irritation of uveal tissues (particularly the ciliary body). A high index of suspicion and the following are essential: a careful history; clinical examination; and ancillary testing, including gonioscopy, ultrasonography, and CT of the eye and orbits. If this condition is suspected and recognized quickly, identification and removal of the foreign body are often curative. If the diagnosis is delayed, ocular complications, such as proliferative vitreoretinopathy and endophthalmitis, result in a poorer visual prognosis.
