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 ...
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 ]
Giant cell arteritis (GCA) often exhibits a wide range of symptoms in its early stages, all of which are related to the localized consequences of systemic and vascular inflammation. The symptoms of GCA include jaw claudication, headaches, and tenderness in the scalp. The most common symptom is headache, which is restricted to the temporal ...
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]
Giant cell arteritis: Giant cell arteritis can result in granulomatous inflammation within the central retinal artery and posterior ciliary arteries of eye, resulting in partial or complete occlusion, leading to decreased blood flow manifesting as amaurosis fugax. Commonly, amaurosis fugax caused by giant cell arteritis may be associated with ...
Retinal vasculitis is inflammation of the vascular branches of the retinal artery, caused either by primary ocular disease processes, or as a specific presentation of any systemic form of vasculitis such as Behçet's disease, sarcoidosis, multiple sclerosis, or any form of systemic necrotizing vasculitis such as temporal arteritis, polyarteritis nodosa, and granulomatosis with polyangiitis, or ...
The halo sign of temporal arteritis should not be confused with Deuel's halo sign, which is a sign of fetal death. [ 3 ] The halo sign is also understood as a region of ground-glass attenuation surrounding a pulmonary nodule on an X-ray computed tomography (CT scan) of the chest.
Biopsy of tissue showing the arteritis (typically inflamed arteries): [12] The sural nerve is a frequent location for the biopsy. In polyarteritis nodosa, small aneurysms are strung like the beads of a rosary, therefore making "rosary sign" a diagnostic feature of the vasculitis.
