Lens luxation occurs when the lens is displaced from its normal position mostly due to blunt trauma. Precise diagnosis at the initial stage is needed because a luxated lens can cause visual disorders.
We present a case report of complete lens luxation following facial trauma. A 68-year-old woman suffered severe lacerations to the face, and fracture of the zygoma and femur in a traffic accident and was transferred to our Emergency Unit. CT scan and ultrasonography revealed displacement of the left lens to the ocular fundus. She was immediately referred for ophthalmologic consultation and was diagnosed as complete lens luxation. The luxated lens showed no urgent symptoms and was treated conservatively, although the fractures were surgically reduced. Visual acuity was restored to 0.6 by wearing a contact lens later.
Maxillofacial injuries, especially midface fractures, are frequently complicated by ocular injuries which can cause serious visual dysfunction. All traumas to the face, particularly fractures of the middle third of the facial skeleton, require ophthalmologic consultation and careful ocular examination.
