VO425 - Video Oculography
Applications
- Non-invasive and easy to use measurement of eye movements.
Patient Database
The integrated extensive database provides a practically unlimited
storage capability. The database works not only with VO425 but also
accepts data from Interacoustics audiometers, middle ear analyzer
bridges, hearing aid analyzers and ABR and TEOAE systems.
| |
|
- Reduced setup time: VO425 normally does not require calibration
- default values can be used.
- For high precision analysis an auto calibration technique
is available.
Nystagmus Analysis
Spontaneous Nystagmus |
- Monocular analysis of horizontal and vertical spontaneous,
positional and positioning nystagmus and its suppression.
|
Caloric Examination |
- Standard analysis for caloric examinations (monaural,
binaural, mono-thermal and bi-thermal).
- Time control for testing and required pauses; all intervals
and test ordering can be configured.
- Standard analysis diagrams showing the slow phase velocity
and the fast phase amplitude and frequency over the cumulation
period

| VO425 Enhanced
Tests Smooth Pursuit |
- Analysis of oculomotor responses to moving visual targets.
- Real-time visualization of patients’ performance.
- Computation of gain and latency.
- Optional integrated visual stimulus (moving targets) on
a monitor or video projector.
|
| Optokinetic Examination
|
- Analysis of direction, velocity of slow phase and gain
in real-time.
- Optional visual stimulation is available on a video/computer
monitor or video projector.
|
| |
| Option
- Rotating Chair |
- Standard analyses and diagrams.
- Support for sinusoidal and trapezoidal stimulus profiles.
- Analog acquisition of chair position and velocity.
