[Topography and angioarchitectonics of the orbital portion of the optic nerve according to ultrasonic findings and data of three-dimensional optic analysis].
Super-sharp gray scale image, highly sensitive digital wide-band Doppler analysis, three-dimensional visualization of vessels in pulsed energy Doppler mode, and three-dimensional optic tomography of the optic disk were used in examination of the posterior segment of the eye in 20 healthy volunteers (40 eyes) aged 20-50 years. Vascular network of the optic nerve was examined under clinical conditions; blood filling of elements of the Zinn-Haller arterial circle, reticular plate, and posterior short ciliary arteries were studied. Vascular architectonics of the retrobulbar space was studied by three-dimensional reconstruction in the energy Doppler mode and biometrical parameters of intraocular and retrobulbar part of the optic disk were determined.
