Giant cell arteritis (GCA), also called temporal arteritis, is an inflammatory autoimmune disease of large blood vessels. [ 4 ] [ 7 ] Symptoms may include headache , pain over the temples, flu-like symptoms , double vision , and difficulty opening the mouth. [ 3 ]
Temporal arteritis, the second type of giant cell arteritis, is also a chronic, inflammatory disease involving mid- to large-sized arteries. [8] Temporal arteritis has a higher incidence in people of Scandinavian descent. [8] However, the incidence rate differs based on population, region and races. [8]
People who have polymyalgia rheumatica may also have temporal arteritis (giant cell arteritis), an inflammation of blood vessels in the face which can cause blindness if not treated quickly. [3] The pain and stiffness can result in a lowered quality of life, and can lead to depression. [ 1 ]
Arteritic anterior ischemic optic neuropathy (arteritic AION, A-AION or AAION) is vision loss that occurs in giant cell arteritis (also known as temporal arteritis). Temporal arteritis is an inflammatory disease of medium-sized blood vessels that happens especially with advancing age. AAION occurs in about 15-20 percent of patients with ...

The deep temporal arteries anastomose with the middle temporal artery. The anterior artery communicates with the lacrimal artery [1] by means of small branches which perforate the zygomatic bone and greater wing of the sphenoid bone. It may also communicate with the ophthalmic artery, a branch of the internal carotid artery. [1]
Giant cell arteritis, [6] also known as temporal arteritis or cranial arteritis, is the most common MGC-linked disease. This type of arteritis causes the arteries in the head, neck, and arm area to swell to abnormal sizes. Although the cause of this disease is not currently known, it appears to be related to polymyalgia rheumatica. [7]
AAION is due to temporal arteritis (also called giant-cell arteritis), an inflammatory disease of medium-sized blood vessels (Chapel-Hill-Conference) that occurs especially with advancing age. In contrast, NAION results from the coincidence of cardiovascular risk factors in a patient with "crowded" optic discs.
