Non-arteritic Jaw Claudication.

A 60-year-old woman with decreased visual acuity in her right eye and right-sided jaw claudication was found to have ocular ischemic syndrome secondary to complete occlusion of the brachiocephalic artery. Although jaw claudication is often considered to be pathognomonic for giant cell arteritis, it has a broad differential diagnosis including both vascular and nonvascular conditions.
