Computerized axial tomography in the detection of intraocular foreign bodies

CAT scanning was used in the localization of intraocular and periorbital foreign bodies in 36 consecutive patients. The method was found to be convenient, well-tolerated by the patient, and provided accurate and useful clinical information. Six cases are described to illustrate clinical situations where traditional localizing methods were unable to supply satisfactory information and where CAT scanning proved to be of significant assistance. This included uncooperative patients, multiple foreign bodies, anterior foreign bodies, and foreign bodies adjacent to the posterior scleral wall.
