Clinical and Imaging Findings One Year Following Traumatic Chiasm Transection.

Traumatic chiasm transection is a rare condition characterized by bitemporal hemianopsia following head trauma. In a study of visual complications following head trauma, only 4.4% of patients suffered from chiasmal injuries. Complete transection of the chiasm is even more rare and best visualized using magnetic resonance imaging (MRI). We report the one-year follow-up of clinical, visual field, and MRI findings of a patient with complete transection of the optic chiasm following head trauma.
