[Ultrasonic Doppler sonography in ophthalmological practice (the Doppler retina)]

This paper presents the case histories of two patients with embolism of the central retinal artery. Non-characteristic headache (lasting longer in one patient than in the other) preceded acute vascular obliteration. In the first case the headache symptom occurred simultaneously with organic findings of stenosis of the carotid artery. The author describes the findings obtained with modified Doppler sonography ("central artery Doppler"). "Retinal hemotachygrams" are analyzed.
