A 76-year-old lady presented to emergency department for left eye sudden visual loss, and fundoscopy found cherry-red spot over the central macula with attenuated retinal vessels. Central retinal artery occlusion (CRAO) was diagnosed. She did not complain of new onset headache, but mild tenderness on palpation over left temporal area with vaguely weak pulsation detected. After the acute management of CRAO pharmacologically, rebreathing into paper bag, and ocular massage; patient underwent hyperbaric oxygen therapy hoping to salvage the ischemic retina while waiting for the erythrocyte sedimentation rate result. Result was >100 mm/hr, and high dose oral steroid was started immediately. Superficial temporal artery biopsy (TAB), performed 2 days after steroid treatment, was diagnostic of giant cell arteritis (GCA). Positron emission tomography and computerized tomography scan revealed vasculitis over thoracic aorta, left common carotid and subclavian artery. Ocular imaging of CRAO, histology of GCA on TAB are discussed with the interesting images.
