The eye socket, or orbit, is a bony cavity that houses the eye, the muscles that move the eye, the surrounding blood vessels, nerves, and fat. Shaped like an empty ice cream cone it is composed of 7 facial bones. Each orbit can be described by the four orbital walls: the orbital roof superiorly which lies between the orbit and the brain and frontal sinusthe medial orbital wall which lies between the orbit and the nose, ethmoid and sphenoid sinusesthe orbital floor which lies between the orbit and the maxillary or cheek sinusand the lateral orbital wall which lies between the orbit and temporal fossa.
Orbital fractures account for a significant portion of traumatic facial injuries. Although plastic surgery literature is helpful, additional pearls and insights are provided in this article from the experience of an oculoplastic surgeon. The fundamentals remain the same, but the perceptions differ and provide a healthy perspective on a long-standing issue.
An orbital fracture is when there is a break in one of the bones surrounding the eyeball called the orbit, or eye socket. Usually this kind of injury is caused by blunt force traumawhen something hits the eye very hard. Any of the bones surrounding the eye can be fractured, or broken.
The eye socket is a bony cup that surrounds and protects the eye. The rim of the socket is made of fairly thick bones, while the floor and nasal side of the socket is paper thin in many places. A fracture is a broken bone in the eye socket involving the rim, the floor or both. The source of the injury is usually a blunt object — baseball, hammer, rock, piece of lumber — and the most frequent place of injury is the home.
Seven bones of the face form a pear-shaped box that surrounds and protects most of the eye. This box is called the orbit. An orbital fracture is a break in one or more of the bones that surround the eye.

A softball to the eye, a tumble to the floor, a gunshot wound while hunting, or a wayward fist at a local watering hole all might send a patient to the trauma center with an orbital or ocular injury. In patients with facial fractures, 20 to 25 percent include orbital involvement at some level. Of this group, over 80 percent will include ocular trauma. The most common patient with ocular or orbital trauma is a young male involved in interpersonal violence.
A facial fracture is a broken bone in the face. The face has a complex bone structure. The facial skeleton consists of the frontal bone foreheadzygomas cheekbonesorbital bones eye socketsnasal bones, maxillary bones upper jaw and mandible lower jaw.
No other facial fracture can be as freighting as trauma to the bones surrounding the eye and for good reasons. Orbital fractures are invariably followed by change in vision that typically includes double vision and pain with eye movement. Timely evaluation and treatment are the only options at restoring and preserving normal visual function. The eyeball globe sits protected in a bed of fat and connective tissue that is in turn housed inside of a thin bony cone.
