A Case of Intraorbital Foreign Body Removed Using A Magnet Under C-arm Fluoroscopy

PURPOSE: We report a case of an intraorbital foreign body removed in a walk-in patient using a magnet under fluoroscopy.
A patient walked into the eye clinic complaining of ocular pain caused by foreign body that pernetrated into his right lower eyelid while mowing the lawn one day before he came to the hospital. Since an orbital foreign body was observed when the patient entered the hospital, and a high-density metallic response was diagnosed within the orbit from a computerized tomogram, we performed an emergency operation to take out the foreign body within the orbit.
We removed the metallic foreign body, which was 5 mm in size and buried in the orbital fat, in an operation using a magnet under fluoroscopy.
This study shows that fluoroscopy and magnets are an efficient operative means of removing foreign bodies that are found within the orbital fat layer and are difficult to access.

  • Figure 1. Preoparative photograph of the patient. The inlet (arrow) is not seen due to a skin fold and lower lid swelling. There is also some periorbital ecchymosis and conjunctival hemorrhage.

  • Figure 2. Preoperative (upper) and postoperative (lower) coronal and sagittal views of orbital CT scans. A foreign body with high density in the inferotemporal area of the orbit was removed by operation.

  • Figure 3. Intraoperative fluoroscopy with a magnet and forceps. Foreign body is captured by a magnet with assistance of forceps.

  • Figure 4. Removed foreign body on the tip of the magnet. The size of removed foreign body is about 5 mm in length and 2 mm in width.
