Ocular calcification may be mistaken for an intraocular foreign body (IOFB) on computed tomographic scan. We present a case of possible multiple IOFBs and discuss the distinction from ocular calcification.

Report of a Case.  An 81-year-old white man presented with a complaint of a foreign body sensation in his left eye. He had been chopping wood the previous day. He was examined by an ophthalmologist who noted a visual acuity of 6/18, a 2-mm corneal perforation superotemporally, and an underlying defect in the iris, which contained a metallic IOFB. Computed tomography confirmed this and also demonstrated another foreign body medially (Figure 1). The patient was referred for magnet extraction of the IOFBs.No laceration could be seen to correspond with the medial IOFB. Roentgenography and B-scan ultrasonography showed only the temporal IOFB. With the administration of general anaesthesia, an aqueous tap was taken for culture and the corneal laceration was
