Background

Nystagmus is a non-voluntary, rhythmic eye movement that usually has well-defined fast and slow phase components in opposite directions. Normal physiological eye vibration can be induced under natural or experimental stimulation conditions; pathological ocular shocks may occur in patients with vestibular disorders with or without external stimuli. Nystagmus is the most common objective sign of vertigo diseases, and prompts nerves from vestibular peripheral receptors to reach brain stem vestibular nerve nuclei through vestibular nerves, and the nerves from the vestibular nerve nuclei emit to form inner longitudinal bundles to innervate bilateral oculomotor nerve nuclei and then emit to innervate extraocular muscles, which is a vestibulo-ocular reflex loop, wherein the nystagmus can be caused by damage of any part. Nystagmus occurs in the most common diseases such as benign paroxysmal positional vertigo, meniere's disease, vestibular neuronitis, vestibular migraine, cerebral stem and cerebellar infarction, intracranial space occupation or inflammation. The eye shake view inspection collects eye movement videos through an infrared camera, can carry out quantitative analysis on eye shakes, and mainly reflects whether functions of a vestibular peripheral system and a vestibular eye movement passage are intact or not and positions pathological changes. There are four main methods for observing eye shake: naked eye examination, Frenzel ophthalmoscopy, electroseismic mapping (ENG), and seismogram mapping (VNG). Among them, VNG is increasingly popular because it can record and playback eye shake video, has high resolution, and can perform quantitative analysis on vertical and horizontal movements of eye shake. Currently existing VNG devices typically need to be equipped with two cameras and an electrical connection box. During the use process, a doctor induces the eye shake through some specific tests, and can use monocular photography or binocular photography for eye movement video recording in software.
