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 ]
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.
People whose ophthalmic artery is affected and don’t receive treatment are at a high risk of blindness, again because poor blood flow to the eyes causes ischemia and irreversible blindness. Alright, so another large-cell vasculitis is called Takayasu Arteritis, and it’s very similar to giant cell arteritis except for two key differences.
The 2012 Chapel Hill Consensus Conference defines large vessel vasculitis (LVV) as a type of vasculitis that can affect any size artery, but it usually affects the aorta and its major branches more frequently than other vasculitides. [4] Takayasu arteritis (TA) and giant cell arteritis (GCA) are the two main forms of LVV. [5]
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.
The 2012 Chapel Hill Consensus Conference defines large vessel vasculitis (LVV) as a type of vasculitis that can affect any size artery, but it usually affects the aorta and its major branches more frequently than other vasculitides. [33] Takayasu arteritis (TA) and giant cell arteritis (GCA) are the two main forms of LVV. [8]
Arteritis is a vascular disorder characterized by inflammation of the walls of arteries, [1] usually as a result of infection or autoimmune responses. Arteritis, a complex disorder, is still not entirely understood. [2] Arteritis may be distinguished by its different types, based on the organ systems affected by the disease. [2]
In cases where symptoms suspicious of giant cell arteritis (GCA) are present, but a temporal artery biopsy reveals fibrinoid necrosis in small vessels branching from the temporal artery, and the absence of the typical GCA histological features, this discrepancy may suggest an alternative diagnosis, as the occurrence of fibrinoid necrosis in GCA ...
