[4] [8] Diagnosis is suspected based on symptoms, blood tests, and medical imaging, and confirmed by biopsy of the temporal artery. [4] However, in about 10% of people the temporal artery is normal. [4] Treatment is typical with high doses of steroids such as prednisone or prednisolone. [4]
The most definitive diagnostic modality is a biopsy of the affected blood vessel however brain biopsy has a low yield, with up to 30-50% of biopsies being normal in suspected cases. [5] This is due to some cases having an irregular distribution of vessel involvement (making biopsy technically difficult) or larger vessels being unable to be ...
A sample (biopsy) of the temporal artery should be obtained to confirm the diagnosis and guide future management, but should not delay initiation of treatment. Treatment does not recover lost vision, but prevents further progression and second eye involvement. High dose corticosteroids may be tapered down to low doses over approximately one year.
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 temporal arteritis. Damage to the blood vessels supplying the optic nerves leads to insufficient blood supply ( ischemia ) to the nerve and subsequent optic nerve fiber death.
Brain biopsy is the removal of a small piece of brain tissue for the diagnosis of abnormalities of the brain. It is used to diagnose tumors, infection, inflammation, and other brain disorders. By examining the tissue sample under a microscope, the biopsy sample provides information about the appropriate diagnosis and treatment.
A temporal artery biopsy (TAB) can be performed to differentiate between the two disease states. [13] As the disease progresses, the arteriosclerosis results in the obstruction of normal blood flow, and potentially the formation of blood clots.
Giant-cell arteritis (GCA) / Temporal arteritis – Affects medium- & large-sized vessels of the head, typically branches of the external carotid artery and namely the temporal artery. Occlusion of the ophthalmic artery results in blindness. Suspicion of GCA necessitates immediate treatment with glucocorticoids and temporal artery biopsy.
The parietal branch of the superficial temporal artery (posterior temporal) is a small artery in the head.It is larger than the frontal branch and curves upward and backward on the side of the head, lying superficial to the temporal fascia; it joins with its fellow of the opposite side, and with the posterior auricular and occipital arteries.
