Video nystagmograph VF5

nystagmography eye recognition softwareVideo nystagmograph VF5 can be built into your personal computer or is available as a complete system, including computer, monitor and printer. The patient's eye movements are recorded using two miniaturized video cameras mounted in a lightweight mask. The video images of the eyes are analyzed within a PC-based system to calculate horizontal and vertical eye positions. The images of the eyes are shown online together with the eye movement traces and analysis diagrams on the computer screen. The application is easy to use in a standard Windows environment.

The infrared 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.

At the picture you can see the result of intelligent eye recognition: the software automatically locates the pupil and outlines the region of interest.

InfraRed VNG system options:

  • Monocular or binocular measurement and analysis
  • Recording of optokinetic velocity, etc.
  • Hot air stimulator for caloric tests
