title: Diagnosis and localization of intraocular foreign bodies by computed tomography.
abstract: Computed Tomography (CT) is the only imaging modality whereby bone and anatomical soft tissue structures are clearly defined. Detection of intraocular foreign bodies (FBs) can be easily obtained by scanning in the axial plane. For the precise localization of FBs, information in two planes is necessary; this is usually achieved by adding a CT study in the coronal plane to the axial plane study. When using a superimposed grid with millimeter calibration on a zoom orbital scan, the accurate location can be calculated. This contribution is of the utmost importance in deciding upon the appropriate approach when surgical removal is indicated.
