Purpose:
To present the evaluation of computed tomography (CT) application for detecting the intraocular foreign bodies.
Material And Methods:
Sixteen computed tomographies of orbit to localise a foreign body were performed in the 2nd Radiology Department at Lublin University School of Medicine from May 1995 to October 1998. During examination 2 mm computed tomography cuts were taken. In almost all cases fundus examination was not possible because of hazy media (cataract, vitreous haemorrhage, endophthalmitis). Pars plana vitrectomy was applied to remove foreign body in all cases.
Results:
In 14 cases a foreign body was localised inside the eye (3 of them were embedded in the wall of the eye) and in 2 cases a double perforation was noticed. With pars plana vitrectomy 12 of 14 intraocular foreign bodies were removed. Two foreign bodies deeply embedded in the wall of the eye were left. One of the two foreign bodies after double perforation was removed from the orbit and the second, which was localized deeply in the orbit, was left.
Conclusion:
The localisation of the foreign bodies using the computed tomography is a very accurate and sensitive method, facilitating further surgery.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
