Optic tract atrophy with cerebral arteriovenous malformations

Direct and transsynaptic degeneration

Mark J. Kupersmith, MD, Marino Vargas, MD, William F. Hoyt, MD and Alejandro Berenstein, MD

Departments of Neurology (Dr. Kupersmith), Ophthalmology (Drs. Kupersmith and Vargas), and Neuroradiology (Dr. Berenstein), New York University Medical Center, New York, NY, and the Departments of Ophthalmology, Neurology, and Neurosurgery (Dr. Hoyt), School of Medicine, University of California, San Francisco, CA.

Three patients with postgeniculate cerebral arteriovenous malformations (AVM) had band atrophy of the contralateral optic nerve. One patient had homonymous hemioptic hypoplasia. These cases might have been construed as demonstrating transsynaptic degeneration across the lateral geniculate nucleus to the anterior visual pathway. However, neuroimaging studies revealed abnormal deep venous drainage remote from the AVM nidus that directly involved the lateral geniculate nucleus and posterior optic tract.

Supported by a Research to Prevent Blindness, Inc., grant to the NYU Department of Ophthalmology and the R.L. Kohn Foundation.

Received April 21, 1993. Accepted for publication in final form July 13, 1993.
