[Doppler ultrasound sonography of the supratrochlear artery in temporal arteritis (author's transl)].

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.
