[Vascular network of choroid melanoma as shown by triple ultrasonic examination].

Twenty-four patients (24 eyes) with choroid melanoma were examined by triplex ultrasonic examination (gray-scale scanning in the real time mode, color Doppler mapping, and pulse wave dopplerography). All tumors possessed individual vascular network with larger vessels with higher bloodflow velocity at the periphery in comparison with the center of the tumor. A large feeding vessel growing into the tumor at the periphery along the internal (facing the vitreous body) surface of the tumor was detected in the overwhelming majority of cases.
