Diagnostic accuracy of computed axial tomography (CT) of the eye and orbit is limited by resolving power and interpretation. Indiscriminate use of the scan is limited by radiation exposure and cost of the modality. The use of CT should be reserved in the ophthalmologist's supply of diagnostic modalities and be used as part of an orderly, logic scheme of diagnostic testing. The scheme proposed advises ordering a B-mode ultrasound before CT.
