Video-based nystagmus measurement device with reduced introduction costs.
VisualEyes515 is a system that allows for low-cost balance function testing (nystagmus testing). When goggles equipped with a CCD camera are worn by the subject, the center position of the pupil is automatically detected, allowing the test to begin immediately. There is no need to apply electrodes or perform calibration as with traditional electro-nystagmography (ENG), significantly reducing the preparation time before testing. The design allows for the templating of test items and content, which simplifies the operation. By attaching an external monitor (optional) to a dedicated PC, it is possible to enlarge and display both the eye movement video and the testing scene, making it convenient to visually observe the nystagmus. At the end of the test, the direction of the nystagmus and the slow phase velocity are calculated, and in temperature nystagmus testing, CP, DP, and VS values are also graphically displayed at the end of the test. If any abnormalities are observed in the test results, marks will be indicated on the graph, making it very useful during diagnosis.

Detailed information
-
【Examination Table】 This is a table for nystagmus examination that has an elevation and lowering function to accommodate the patient's body shape. By installing a chin rest and monitor, smooth examinations can be conducted.
-
【Caster-equipped Stand】 This is a stand for video nystagmography that can accommodate goggles and computers. It features a simple design and is equipped with large casters that excel in quietness, allowing for the movement of the nystagmograph outside the examination room. Stainless shelves, handles, and drawers can be added as options.
-
【Examination Chair】 This is an examination chair with a lifting function. It features a durable aluminum molded base that minimizes the height difference with the floor. By adding an optional backrest, patients can sit stably, making it ideal for eye movement tests.
-
【Chin rest】 It is a device used to stabilize the patient's head. During the examination, when stimulus images are displayed on the monitor for the patient to see, stabilizing the head allows for a more accurate confirmation of nystagmus.
-
【Monitor Arm for Eye Movement Testing】 This is an arm used to adjust the monitor to a position where the patient can easily view the stimulus images. By securing the arm to the examination table, the stimulus presentation monitor can be freely adjusted up, down, left, and right. It is compatible with VESA mounting standards (75x75, 100x100mm), making it suitable for many displays.
