Department of Ophthalmology, Massachusetts Eye and Ear Infirmary, Boston 02114, USA.
In a case of traumatic avulsion of the optic nerve at the anterior chiasm, MR imaging provided highly specific images of the injury site, including the absence of the optic nerve within the optic canal and the point of transection at the anterior portion of the chiasm. This was confirmed clinically and histopathologically. MR imaging should be considered in cases of suspected chiasmal injury.
