Localisation of intraocular and intraorbital foreign bodies using computed tomography

Clin Radiol. 1989 Nov;40(6):610-4. doi: 10.1016/s0009-9260(89)80320-4.


Accurate localisation of foreign bodies in the region of the orbit is vital for correct management. Fifteen patients with such foreign bodies are described. Computed tomography (CT) of the orbits proved accurate in differentiating extraocular and intraocular foreign bodies, and in localisation within the globe. If a foreign body is visible on a plain radiograph, axial 6 mm thick CT sections will demonstrate it in all cases. If plain radiographs are negative or equivocal, 3 mm thick CT sections are necessary. Coronal scans are of limited usefulness.
