[Doppler sonographic findings in intraocular tumors].
B-scan-ultrasonography combined with Doppler measuring facilities (DUPLEX technology) was applied in 31 patients with intraocular tumors (27 choroidal melanomas, 4 cavernous hemangiomas of the chorioid). In all but 2 patients, Doppler frequency shift was observed inside the tumor, which was interpreted as being caused by high-velocity blood flow (maximum 10 cm/s). After conservative treatment (beta irradiation with ruthenium 106) the Doppler signals decreased in height in some patients. After 6-8 months, no frequency shift could be determined. Choroidal hemangiomas showed similar signal behavior, so that differential diagnosis by means of Doppler analyses does not seem to be possible.
