[Ultrasonic tomography of neurogenic tumors of the orbit].
The results of a comprehensive ultrasonic examination of 12 patients with tumors of the eye orbit are described. A low echogenicity as well as heterogeneity of the echo-structure and of the contours' sharpness are the main sonographic features of the mentioned tumors. An examination of a vascularization degree in patients with gliomas of the optic nerve showed no blood circulation inside tumors; while a collateral blood circulation was detected in patients with meningiomas of the optic nerve. A compression of the ocular artery by the tumor and reduced hemodynamic indices were found to be typical. Finally, a triplex examination of the orbit makes it possible to diagnose tumors of the optic nerve.
