An orbital blowout fracture is a fracture or break in the small bones that make up your eye. The orbit, or eye socket, is the cavity of the skull that holds the eye. An orbital blowout can occur when an object strikes the orbit with blunt force. This injury is commonly the result of a fist, baseball or tennis ball that strikes the eye. The bony orbit's job is to protect the eyeball.
The orbit, which protects, supports, and maximizes the function of the eye, is shaped like a quadrilateral pyramid, with its base in plane with the orbital rim. Seven bones conjoin to form the orbital structure, as shown in the image below.he superior orbital fissure is bounded by the lesser and greater wings of the sphenoid. The greater wing of the sphenoid, the maxilla, and the palatine bones of the orbit form the boundaries of the inferior orbital fissure. The optic canal is at the apex of the orbit and lies within the sphenoid bone.
