yVOG-Glass operation screen

Home screen

Enter or search for patient information to begin the examination. Eye images can be recorded and played back, and data can be stored for each patient. Data can be easily managed chronologically and by examination item.

Calibration screen

The corneal diameter is measured and calibration is performed.
Calibration using visual targets is unnecessary, significantly reducing preparation time before starting an examination. It’s quick and easy to use whenever you need it.
The screen layout and button shapes are designed with ease of use on touch panels in mind.

Inspection screen

The examination is conducted while viewing the live display of analysis results and eye movement images. Eye movement images are recorded and saved, head position angle information is recorded, and audio is recorded simultaneously.

Diagnostic screen

The recorded video and the analysis results graph are displayed simultaneously. Nystagmus arrows are automatically displayed as reference points based on the analysis results graph. You can also specify the analysis range to display slow phase velocity, etc.

Report screen

Select the test results, check the nystagmus arrows, and select the graph sections you want to modify or transfer to create a report. The created report can be printed or saved as a PDF.
(A printer is required for printing.)
