AB  - Detection and localization of known orbital foreign bodies with computed tomography was evaluated using a model that simulates as closely as possible in vivo conditions. The GE 8800 scanner proved to be an excellent instrument for detection and localization of most orbital or intraocular foreign bodies above certain minimum levels of detectability. The minimum detectable size varied according to the material, for example, 0.06 mm3 for steel, 1.82 mm3 for auto window glass in intraocular position, and slightly larger sizes for extraocular location. Small wood fragments were not detected.
