Fractures of the bones around the eye usually occur from blunt trauma, such as a sports injury or a fall with injury to the nose and cheekbone ( blow-out fracture). Fractures are often detected by x-rays or a CT scan which also help determine if tissues/muscles surrounding the eye are trapped in the fractures. These injuries often require prompt surgical treatment to prevent long-term complications such as double vision, loss of vision, and abnormal appearance.
