A 72-year-old woman experienced anterior ischemic optic neuropathy in her left eye. The funduscopic and fluorescein angiographic findings were strongly suggestive of giant cell arteritis. Temporal artery biopsy revealed extensive calcification in the vessel wall consistent with calciphylaxis. This unusual disorder should be considered in the differential diagnosis of anterior ischemic optic neuropathy, particularly the arteritic form.
