Traumatic monocular blindness and associated carotid injuries.

Cases of traumatic carotid injuries have been described sporatically in the literature since the early 19th century. The general availability of angiography in the 1930s caused a significant increase in the number of articles published concerning this subject, but reports of carotid artery injuries remain uncommon. In one series of 2000 head injury patients, carotid injuries were recognized in only 0.5% of patients.
 Of the various types of injury the carotid artery can sustain, the development of intracavernous false aneurysm is potentially the most devastating. The syndrome of traumatic monocular blindness and severe delayed epistaxis in association with carotid injuries and basilar skull fractures was first reported by Barth and more recently by Chambers et al. Mortality rates of 20% to 40% have been attributed to a delay in diagnosis.
