Ultraschall-Doppler-Sonographie der A. supratrochlearis bei Arteriitis temporalis: Ist das Erblindungsrisiko abschätzbar?

Abstract

The risk of ocular involvement in temporal arteritis is difficult to assess in the individual case. Using Doppler ultrasound sonography a clearly reduced flow or arrest of flow in the supratrochlear artery of the amaurotic side could be demonstrated in three patients. Attempts to compress branches of the external carotid artery caused no change of flow behaviour. Doppler sonography thus permits assessment of involvement of orbital vessels. This indicates the risk of loss of vision.

Ultrasonography of the Temporal, Periorbital and Carotid Arteries in the Diagnosis of Giant Cell Arteritis and its Neuroophthalmological Complications

“…In one study, the diagnosis of stenosis and occlusion reduced specificity [15]. Absent flow and other abnormalities in Doppler sonography of the periorbital arteries (DSPA) as an indicator of arteritic thrombosis have been considered to be helpful in determining the risk of blindness [6,7,10,12].…”
