Capillary hemangioma is one of the most common tumors of the head and heck in infants but it occurs rarely in adults. The treatment of capillary hemangioma is by either a watchful waiting for its spontaneous regression, intralesional corticosteroid injection, or surgical intervention. Surgery is indicated when there is no evidence of regression of the tumor or the patient experiences a decreasing in visual acuity. We present a case of retrobulbar hemangioma. The patient was a 32-year-old man who complained of right temporal pain, impairment of his visual field, limitation of the upward gaze and proptosis of the right eye. Magnetic resonance imaging and sonography revealed a 3 x 2 x 2 cm tumor in the right retrobulbar space. The tumor was removed using a Caldwell-Luc operation combined with inferior orbitotomy. Since surgery, there have been no visual impairment, no surgical complication, and no sign of recurrence.
