Giant cell arteritis

Also called temporal arteritis. A condition which causes the inflammation of temporal arteries. It can cause blindness when the inflammation effects the ophthalmic artery.

arteritis, temporal 

An inflammatory disease of the wall of arteries, mainly of the extracranial vessels, which occurs in people who are over 60 years of age. The condition is characterized by headache and pain in muscles and joints, such as those of the jaws, tender or non-pulsating temporal artery, and sometimes fever. A sudden loss of vision in one eye (amaurosis fugax) may occur in the first few weeks after the onset of the disease due to an occlusion of either the central retinal artery or of the short posterior ciliary arteries that supply the optic nerve. Prompt administration of systemic corticosteroids (e.g. hydrocortisone) has been found to be of great value in the management of this condition. Syn. giant cell arteritis (strictly speaking this term is usually reserved for a more generalized condition). See amaurosis fugax; ischaemic optic neuropathy; Adie's pupil.
