PURPOSE: To report a case of an occult intraocular foreign body missed on initial presentation. To our knowledge, this is the first reported case of fiberglass as an intraocular foreign body. METHODS: A case report in which the clinical presentation of the patient was documented by color anterior segment and fundus photographs, optical coherence tomography (OCT), and computed topography (CT) of the orbit. RESULTS: A 34-year-old male was referred for the evaluation of an acute unilateral preretinal hemorrhage of undetermined origin. Three months before his presentation, he had a foreign body sensation while cutting fiberglass, which lasted for several hours. He denied having any visual complaints until his presentation 3 months later. On anterior examination, a small paracentral corneal scar was noticed. There was no cell or flare. A small iris defect inferior nasal with an adjacent area of broad based peripheral anterior synechia on gonioscopy was noted. On funduscopy, a large subretinal elevation with an underlying hemorrhage adjacent to the disk with a white foreign body partially imbedded in the retina was seen. A vitreous hemorrhage was overlying the macula. Because there were no signs of infection or inflammation, surgical intervention was avoided. Barrier laser was performed around the subretinal elevation. CONCLUSION: Occurrence of intraocular foreign bodies, although not uncommon, has a varying presentation. Most often devastating and dramatic, clinical signs may not be obvious or appreciated on thorough examination, especially when the offending object is very small. Intraocular foreign bodies composed of inert material (i.e., glass/fiberglass) can leave the eye without inflammation, further making the diagnosis difficult.
