Abstract

PURPOSE: We report a case of an intraorbital foreign body removed in a walk-in patient using a magnet under fluoroscopy.
METHODS
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.
RESULTS
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.
CONCLUSIONS
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.
