Title	An unusual case of diplopia caused by an intraorbital foreign body
Abstract Nr.	3033

Purpose	Remind the reader that an intraorbital foreign body can be an important cause of diplopia.
Methods	Case presentation
Results	A 51-year-old man presented with a history of intermittent diplopia. His problems started a few weeks earlier after a trauma with an exploded beer bottle. At the time of the accident, a big laceration of the nose and the right lower eyelid was sutured at the emergency department. At this time, he was not seen by an ophthalmologist. Computed tomography (CT) of the orbit revealed two radiodense foreign bodies in the right orbit, located between the rectus inferior muscle and the orbital floor. Based on his history and CT images, the possibility of retained glass particles was considered. Exploration of the right orbit by an infra-orbital approach was planned. The glass particles were removed without causing any further damage to the inferior oblique or inferior rectus muscle fibers. One-week follow-up examination showed a remarkable improvement with no complaints of diplopia in primary gaze anymore.
Conclusion	This case illustrates that an intraorbital foreign body can be an important cause of diplopia, and should not be forgotten in the differential diagnosis. Thorough history, clinical and radiological examination are recommended when a foreign body is suspected. An early diagnosis is necessary and can prevent long-term complications.
