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 ...
However, a severely atherosclerotic carotid artery may also cause amaurosis fugax due to its stenosis of blood flow, leading to ischemia when the retina is exposed to bright light. [12] "Unilateral visual loss in bright light may indicate ipsilateral carotid artery occlusive disease and may reflect the inability of borderline circulation to ...
This form of ischemic optic neuropathy is generally categorized as two types: arteritic AION (or AAION), in which the loss of vision is the result of an inflammatory disease of arteries in the head called temporal arteritis, and non-arteritic AION (abbreviated as NAION, NAAION, [1] or sometimes simply as AION), which is due to non-inflammatory ...
“In addition, we know these vessels change in response to a variety of systemic vasculopathic conditions including hyperlipidemia, hypertension, diabetes, and inflammatory disorders that can all ...

Giant cell arteritis contains two different types of arteritides that are almost indistinguishable from one another. [2] It includes two types, temporal arteritis and Takayasu arteritis. Both types contain an occupancy of medium- and larger-sized arteries which are categorized based on the infiltration of the giant cells. [2]
Optic neuropathy is damage to the optic nerve from any cause. The optic nerve is a bundle of millions of fibers in the retina that sends visual signals to the brain. Damage and death of these nerve cells, or neurons, leads to characteri
