  • Method for diagnosis of early stage of optic nerve blood supply disturbance
    Patent number: 5042490
    Abstract: The invention is a method for diagnosis of early stage of optic nerve blood supply disturbance resides in that the state and localization of the optic nerve is determined by virtue of ultrasonic scanning, then a distance from the eyelid anterior surface of the ciliary arteries supplying said optic nerve is measured, whereupon the state of hemodynamics in said ciliary arteries is determined on the thus-measured distance with the aid of ultrasonic pulse-dopplerography, by measuring the linear and volumetric blood flow velocities in said arteries, a value of said linear blood flow velocity below 9 cm/s and of said volumetric blood flow below 5 ml/min are indicative of an early stage of optic nerve blood supply disturbance.
