VN415 / VO425

A complete nystagmographic and oculographic analysis

Vestibular Analysis (VN415)

Video Nystagmography provides ideal conditions for the observation, measurement and analysis of eye movements.

The VN415 module is designed for convenient computer aided analysis of positional and caloric testing. Features rapid data transfer technology enabling high video quality and precise measurements with all results stored in the OtoAccess™ database.

VN415 is a completely portable VNG system with no bulky equipment to get in the way. Start the software, place the Goggles on the patient and you are ready to test.

VN415 is the standard VNG platform with standard protocols for testing

Spontaneous Nystagmus
Bithermal Caloric

  • Oculomotor Analysis(VO425 )

    Our VO425 software module is designed for clinics that carry out detailed balance evaluations. The VO425 contains all the features of the VN415 plus computer aided analysis of oculomotor tests.

  • Ocular Stimuli
    Full field of view visual stimuli are software generated from your laptop or PC connected to a video projector or an LCD screen. The digital stimuli are ideal for both pediatric and adult populations and include several default and imported patterns by your choice.

  • Automatic or Manual
    The system produces highly accurate test results, but you can switch to manual edit mode in all tests to overrule the automatic analysis. In manual edit mode you can add or delete nystagmus marks, change slopes and define alternative areas of analysis.

    VO425 offers the same test protocols as VN415 and additionally expands into oculomotor tests with standard protocols for

    Smooth Pursuit
    Optokinetic testing
