[Dissection of the internal carotid artery with ascending thrombosis of the ophthalmic artery as a rare differential diagnosis of post-traumatic amaurosis].

The case of a 30-year-old patient is reported who presented with a right-sided amaurosis fugax and a simultaneous frontobasal fracture that had occurred after a fall. By CT angiography and MRI angiography obstruction of the ophthalmic artery following a dissection of the internal carotid artery with ascending thrombosis could be demonstrated. There was a lack of further neurological deficits because of sufficient perfusion of the cerebral arteries by the arterial circle of the cerebrum. Among the etiological variety of types of posttraumatic amaurosis, this rare cause should be taken into consideration in the etiology, diagnosis and therapy, if appropriate.
