Problems solved by technology

[0010] However, since electronystagmography does not directly capture signals from the extraocular muscles, it cannot be considered to provide information on accurate eye position, and measurement of vertical eye movements is difficult due to upper/lower lid lift The electrical signals from the rectus muscles overlap with those from the superior/inferior rectus muscles, so there is a problem of not being able to distinguish between the two eye movements
[0011] Also, the electronystagmography method has a problem that the method is very sensitive to changes

Abstract

The present invention relates to a nystagmus video test device and method and, more specifically, to a nystagmus video test device and method using an infrared camera, the device and the method rotating a patient to the left and right so as to influence a vestibular organ of the patient, and analyzing, on the basis of the rotation condition of the patient, an infrared pupil image captured by the infrared camera, so as to perform a nystagmus test on the patient.

Description

technical field [0001] The present invention relates to a video nystagmus testing device and method, and more specifically, to a video nystagmus testing device and method using an infrared camera, which affects the patient's vestibular organs by turning the patient left and right, and according to the above-mentioned patient The nystagmus test is performed by analyzing the infrared eye images captured by the infrared camera under the rotational conditions. Background technique [0002] Vertigo is a very common condition, estimated to be experienced by one in five adults more than once a year. [0003] Usually, vertigo occurs when there are abnormalities in the ear (peripheral), brain (central), heart, eyes, etc. [0004] As one of the human abilities, when the head is swaying, the field of view can also change with the swaying of the head. The vestibulo-ocular reflex (Vestibular-Ocular Reflex: VOR) occurs in order to prevent our body from changing the field of vision when ...
