A fracture of the orbital wall of the eye. The rim of the eye is not fractured so a blow-out fracture is not palpable. Clinical features include enophthalmus (i.e. the eye appears sunken in the orbit) and diplopia (double vision). This injury is caused by a sudden increase in intraorbital pressure, such as when a squash ball or fist hits the rim of the eye.
