VO25 - Video Oculography
Description
The VO25 system can be built into your
personal computer or is available as a complete system, including computer and
screen.
The patient’s eye movements are recorded using miniaturized video cameras
mounted in a lightweight mask. The video images of the eye are analyzed within
a PC-based system to quantify horizontal and vertical eye position. The image
of the eyes is shown online together with the eye movement traces and analysis
diagrams on the computer screen. The application is easy to use in standard
Windows environment.
The camera is mounted in a combined mask for both recordings in darkness and with free-field-of-view. The mask is easily darkened with a magnetic cover plate.
Compared to the VN15 the VO25 offers optional visual stimulus generation for calibration, optokinetic, smooth pursuit and saccade testing.
System Options:
Monocular measurement
and analysis.
Recording of chair
position, optokinetic velocity, etc.
Portable suitcase
integration to allow bedside examinations
and recording of transient symptoms.
