• Doppler shifts were detected using duplex and color Doppler scanning in 41 of 42 patients with malignant melanomas of the uvea. Mean maximum tumor systolic velocity was 18.8±7.6 cm/s. Time-averaged maximum velocity in the tumor vessels was 12.3±5.3 cm/s. Maximum tumor velocity increased in four of eight tumors and was unchanged or had diminished in the other four 2 to 3 days after ruthenium plaque irradiation. Doppler shifts were undetectable in three tumors, markedly reduced in three tumors, and unchanged in one tumor 1 to 4 months after treatment. We detected minimal non-pulse-synchronized Doppler shifts in one of three tumors, and no shifts in the remaining two tumors 1½ to 4 years after therapy. Color duplex scanning allowed a rapid overview of tumor vasculature and facilitated study of individual vessels.
