GIANT CELL arteritis (GCA) is a systemic, necrotizing vasculitis affecting medium- to large-sized arteries. The most frequently involved arteries are the superficial temporal, vertebral, ophthalmic, and posterior ciliary.1,2 The incidence of GCA has been reported to be as high as 25 per 100,000 patients.3 Familiarity with the many systemic manifestations of GCA is essential for ophthalmologists.
