Abstract

We compared the results of ocular pneumoplethysmography in nine patients who had a temporal artery biopsy (TAB) diagnostic of giant-cell arteritis with results of ocular pneumoplethysmography in nine patients with normal TAB results and 112 patients with anterior ischemic optic neuropathy or central retinal artery occlusion assumed to be nonarteritic. The mean +/- SD ocular pulse amplitude with ocular pneumoplethysmography was 3.9 +/- 1.8 mm in the group with abnormal TAB results and 10.6 +/- 4.0 mm in the group with normal TAB results. Every patient with abnormal TAB results had an average calculated ocular blood flow less than 0.60 mL/min, while only one patient with normal TAB results fell in this range. The average calculated ocular blood flow had a sensitivity of 100% and a specificity of 93.4% in the diagnosis of giant-cell arteritis, with a diagnostic accuracy of 93.9%. These results rival the diagnostic accuracy of the erythrocyte sedimentation rate and TAB results.
