Computed tomography of intraorbital foreign bodies.

Computed tomography (CT) has been shown to be an important diagnostic tool in the evaluation of intraorbital foreign bodies (IOFB). In order to further analyze the capacity and limitations of CT in this respect, 55 cases with IOFB (intraocular and extraocular) detected at CT were retrospectively analyzed. It was shown that CT was an excellent diagnostic modality in detecting and localizing IOFB of different material and superior to ultrasonography in this respect. Still, even with high resolution CT, there are some limitations of this modality that are discussed. CT is recommended as the primary diagnostic tool in the detection and localization of intraocular and extraocular foreign bodies.
