[Diagnostic value of ultrasonography and ophthalmodynamometry in the diagnosis of stenosis and occlusion of the internal carotid artery].

The results of ultrasonographic and ophthalmodynamometric investigations were evaluated in 40 patients with stenosis or occlusion of the internal carotid artery. An agreement was demonstrated between the results of ultrasonographic and angiographic investigations in 85% of cases, and between ophthalmodynamometric and angiographic findings in 65% of cases. In 20% of cases ophthalmodynamometrically silent occlusion of the internal carotid artery was demonstrated. These results show that supplementation of ophthalmodynamometric investigations with ultrasonography increases the proportion of correct diagnoses.
