- Fractures of the orbital floor typically result from direct, blunt trauma with a rounded object to the eye.
- When describing associated ophthalmic and/or neurologic injury, to consultants in particular, be aware of appropriate terminology to use in relaying the presence or absence of related physical findings.
- The following ophthalmic abnormalities are commonly associated with orbitla floor fractures:
-- Enophthalmos (eye receded into the orbit) may occur when globe is
displaced posteriorly, often with prolapse of tissue into maxillary sinus.
-- Orbital dystopia (affected eye in a lower horizontal plane than the other) may
occur due to the pulling of entrapped muscle and orbital fat.
- Remember to check for facial sensation, as decreased sensation along the ipsilateral cheek, upper lip, or upper gingiva suggests injury to the infraorbital nerve.
- The presence of a teardrop-shaped pupil suggests that the globe ruptured.
