Abstract

Three noninvasive techniques used in the evaluation of carotid occlusive disease were compared in the same population group. The cerebrovascular Doppler examination (CDE) had an accuracy rate of 89%, oculopneumoplethysmography (OPG-Gee) an accuracy rate of 94%, and supraorbital photoplethysmography (SOPPG) an accuracy rate of 86%. With the combined use of the CDE and the OPG-Gee, the accuracy rate increased to 96% when the results were concordant, and the false-negative rate dropped to 3%. The data would suggest that the combined use of the CDE and the OP-Gee offers an advantage over either technique used individually.
