Iatrogenic orbital hematoma: an exceptional complication of upper gastrointestinal endoscopy.

Iatrogenic orbital hematoma is a rare event, most often manifested by a painful exophthalmos that could compromise the patient's visual prognosis. We report the case of a 51-year-old female patient with a history of non-ischemic dilated cardiomyopathy and high blood pressure, who developed a painful exophthalmos following an upper gastrointestinal sedation-free endoscopy. The diagnosis of an intra-orbital hematoma was made by computed tomographic scan and a conservative attitude was adopted after a thorough ophthalmological examination. Upper endoscopy may trigger this condition in the presence of pre-existing predisposing factors such as blood clotting disorders, high blood pressure or vascular malformation. This case highlights an uncommon complication of a commonly performed endoscopy that endoscopists should be aware of to provide safe and optimal examination.
