role of colour doppler imaging in follow up of choroidal malignant melanoms

We evaluated the blood flow in nine cases of choroidal malignant melanoma before and after radiotherapy using colour doppler imaging. Tumoral blood flow was detected in all cases prior to treatment. Significant flow reduction was noted as early as the first post-irradiation month. Tumour regression occurred in four cases and was preceeded by slowing or complete cessation of tumor circulation in all cases. On the other hand, 3 recurrences occurred and were preceeded by or accompanied with increase in Doppler velocities in tumolur vessels
