Ophthalmodynamometry and ocular pneumoplethysmography for detection of carotid occlusive disease.
The accuracy of ophthalmodynamometry and ocular pneumoplethysmography for predicting pressure-significant lesions of the internal carotid system was compared in a series of 119 consecutive patients (210 arteries) having cerebral angiography. Overall accuracy (92.5%) for ocular pneumoplethysmography was significantly better than that for ophthalmodynamometry (76%). The difference was most apparent in predicting abnormality (85% for ocular pneumoplethysmography and 49% for ophthalmodynamometry), particularly for bilateral lesions (80% for ocular pneumoplethysmography and 37% for ophthalmodynamometry). There were few false-positive results with either test.
