BACKGROUND A retained ferrous intraocular foreign body (IOFB), introduced via penetrating ocular trauma, may result in ocular siderosis and visual loss that may occur after days or years. If diagnosis is delayed, therapy may also be delayed, resulting in a poor outcome. The present report presents the case of a 58-year-old man with a retained iron IOFB and late-onset siderotic glaucoma 1 month after the initial trauma. CASE REPORT A 58-year-old man presented with redness and eye pain in the right eye for 1 month after ocular trauma. His visual acuity was very good, with no sign of eye strain. High intraocular pressure had been detected for several weeks, but the B-scan ultrasound and fundus examination were normal and the reason for the high intraocular pressure was unknown. He was later transferred to our senior hospital. The diagnosis of IOFB was confirmed by computed tomography (CT) scan and ultrasound biomicroscopy (UBM). The patient was successfully managed by vitrectomy. CONCLUSIONS This report highlights that a retained IOFB can be challenging to diagnose and that cases associated with siderotic glaucoma require multiple investigations. Early detection of the IOFB using the right tools is vital to reduce the risk of siderotic glaucoma. Although the fundus examination was normal after ocular trauma, the use of CT scan and UBM assisted in finding the IFOB and the patient was successfully treated by vitrectomy.
