The severity of an orbital outer wall fracture depends on the extent of the fracture. A fracture of the external wall of the eye is usually the result of direct violence to the lateral aspect of the orbit. The main clinical manifestation is localized swelling and pain, and after 2-3 days the localized ecchymosis spreads to the periphery, resulting in ecchymotic skin changes in the upper and lower eyelids. In severe cases, the fracture may result in mild contusion of the eye due to violence, or even irreversible damage, resulting in blindness in one eye. In addition, some patients may have a combination of intracranial fractures, resulting in soft tissue contusions and even cerebral hemorrhage, which can be clearly diagnosed by cranial CT examination and require timely treatment.
