Abstract
We evaluated the efficacy of spectral and color Doppler sonography as a screening
procedure for intraocular tumors. Thirty patients who had intraocular tumors were
included in the study. Abnormal Doppler shifts were demonstrated 19 of 20 patients
with choroidal malignant melanomas, especially at the base of the tumors. The average
maximum systolic blood flow velocity in the vessels of these tumors was 17 ± 6.8 cm/sec
(14 to 28 cm/sec). In one of the choroidal metastasis, blood vessels were seen around
the lesion with a 14-cm/sec maximum peak systolic velocity. Intratumoral vascularity
could not be demonstrated in the other tumors. Spectral and color Doppler imaging
is a relatively new and promising modality in the management of intraocular tumors
and may help to provide a more precise preoperative histological diagnosis noninvasively;
however, long-term follow-up is needed.
