2. Figure 1
(Patient 1) Magnetic resonance imaging. A, postcontrast, T1-weighted axial image showing abnormally wide and elongated intracavernous and supraclinoid segments of the carotid artery on both sides (black arrows). Note that the distal cavernous and proximal ascending segments extend abnormally far forward into the superior orbital fissure (white arrowheads). B, T1-weighted coronal image showing the right-sided intracranial optic nerve (black arrow) is compressed by the ascending segment of the carotid artery (white arrowhead). Note how the right optic nerve is molded over the dome of the artery.

(Patient 10) T1-weighted magnetic resonance imaging in the coronal plane. A, right-sided intracranial optic nerve (black arrow) is compressed by the ascending vertical segment of the carotid artery (white arrowhead). Note how the optic nerve appears thin and molded over the dome of the artery. B, chiasmal bar appears thin, and right side of the optic chiasm is displaced upward (black arrow).

5. Figure 4
(Patient 12) Left-sided oculomotor nerve palsy with signs of aberrant regeneration. (Top) During gaze to the left, left-sided ptosis is apparent. (Bottom) When the patient gazes to the right, the left, upper eyelid undergoes synkinetic contraction. Notice the larger pupil and incomplete adduction of the left eye, which are additional signs of third cranial nerve dysfunction.

6. Figure 5
(Patient 12) T1-weighted magnetic resonance image in the coronal plane showing marked compression of the posterior segment of both optic nerves (thin, black arrows) by ectatic carotid arteries (white arrowheads) at the junction with the optic chiasm. In addition, the left-sided intracavernous carotid artery (fat, black arrow) is markedly widened.

Goldmann visual fields showing a variety of patterns of nerve fiber bundle injury. (Top) Patient 15 has an inferior nasal step of Ronne, with an inferonasal depression found during static checking with the I4e target in his right eye (I2e, I3e, and I4e isopters shown). The visual field of his left eye is normal (I1e, I2e, and I4e isopters shown). (Middle) Patient 3 has a discrete incomplete inferior arcuate scotoma deep to the V4e target in her right eye (I2e, I4e, and V4e isopters shown). Extensive visual field loss with only two small scraps of peripheral visual field are remaining in her left eye (III4e and V4e isopters shown). (Bottom) Patient 9 has bilateral absolute arcuate visual field defects (I4e, II4e, and V4e isopters shown).

8. Figure 7
T1-weighted magnetic resonance images in the coronal plane of the patients whose visual fields are depicted in Fig 6. A, in patient 15, the right-sided optic nerve (thin, black arrow) is compressed by the carotid artery (fat, black arrow). The optic nerve is thin and pinned in between the artery from below and the gyrus rectus from above. Notice also how the carotid artery displaces the optic nerve and gyrus rectus upward. B, in patient 3, the right-sided optic nerve (black arrow) is compressed by the vertical ascending segment of the carotid artery (white arrowhead). The nerve is thin and molded over the dome of the artery. The left-sided optic nerve is markedly thin and cannot be visualized on this image. C, in patient 9, the right-sided optic nerve (black arrow) is compressed by the vertical ascending segment of the carotid artery (white arrowhead). The nerve is thin and molded over the dome of the artery. The left-sided optic is compressed similarly but is not visualized on this image.
