A peculiar orbital roof blow-in fracture.

An orbital blow-in fracture is defined as a displaced fracture of the orbital rim or wall when the fractured bone fragment is pulled into the orbit, resulting in a decreased orbital volume. Orbital blow-in fractures is generally localized at the orbital roof. Surgical treatment is required and should be early to avoid any damage to the visual. We report a peculiar case of indirect blow-in orbital roof fracture associated with fracture of the parietal bone.
