Fractures of the Orbit
Introduction
A severe blow to the face can fracture any of several bones that form the orbit (the bony cavity that contains the eyeball, muscles, nerves, and blood vessels, as well as the structures that drain tears). (See also Overview of Eye Injuries .) Pain and swelling may develop, and double vision or decreased vision may occur. Computed tomography (CT) is done. Sometimes the fracture is repaired surgically. Fractures of the floor (bottom) of the orbit (blowout fractures) are common, but fractures of other parts of the orbit also occur. Occasionally, the eyeball itself also is damaged.
