Detailed Description

The noun explains:

and (3) eye shake: nystagmus (nystagmus), called nystagmus for short, is an involuntary, rhythmic, reciprocating eye movement. Specifically, it appears that the object is most clear when imaged in the fovea, and in order to keep the object imaged in the fovea, the eye must undergo corrective movements, which are eye shakes, which include slow and fast phases. Peripherical lesions of the vestibular system, central lesions, and certain ocular diseases can cause ocular shock. By observing and analyzing the eye shake, the examination of the vestibular function can be greatly facilitated.

And (3) vision fixation inhibition: when the eye shake occurs, the patient stares at a fixed target point to see, and if the eye shake speed and amplitude obviously decrease, the fixation inhibition is successful, which often represents peripheral diseases; after the vision fixation, the amplitude of the velocity of the eye shock is not reduced, but enhanced, which means that the vision fixation inhibition fails, often representing a central disease.
