[Problems in diagnosis and extraction of foreign bodies from the orbit associated with pain].
The aim of this study was to present the troubles and significance of a proper diagnosis of a foreign body which caused a double perforation of the eyeball and was retained in the orbit. Another reason for this case report was the intensive pain associated with the existing foreign body in the orbit. A male, 54 years old, had a perforating wound of the eyeball caused by a metal foreign body, which stayed in the orbit close to the scleral wall. X-ray and echographic examinations of the orbit were not conclusive regarding the question whether this foreign body was situated within or outside the eyeball. Only CT imaging showed that foreign body produced a double perforation of the eyeball and was externally close to the sclera. Foreign body was extracted by transconjunctival anterior orbitotomy through the inferior fornix, using the electromagnetic probe. Since the first day of injury and up to the eighth day, the patient had intensive deep orbital pain, which was alleviated only partially by analgetics. It could not be explained by secondary glaucoma because IOP was normal or by an inflammatory process, or in any other way. Only the extraction of foreign body from the orbit led to the complete relief of pain. We believe that the pain was caused by compression of foreign body to some of scleral sensory nerves. X-ray and echographic examinations of the orbit are not always a reliable proof in the proper evaluation whether foreign body is within or outside the eyeball in the orbit. Precise diagnosis can be made only by CT imaging. The pain in the orbit may be caused by compression of foreign body to sensory nerves.
