Our VNG comes in two versions, each with increasing scope. Both the VN415 and VO425 can be delivered in monocular or binocular camera configurations.
Gaze (only VO425)
Saccade (only VO425)
Smooth Pursuit (only VO425)
Optokinetic testing (only VO425)
The combi Goggle
The combi Goggle is lightweight with a direct FireWire® connection to a laptop or desktop computer. It has an easy-to-fit magnetic cover to allow for both occluded and unoccluded measurements and a built-in fixation light to simplify testing. With adjustable mirrors and vertical, horizontal and focus adjustments for each camera, the fit is ideal for all patients, regardless of head size. The disposable foam cushions allow for a hygienic solution for each patient and provide a comfortable, secure and lighttight fit.
Optimized lighting in the goggle results in significantly improved eye-tracking during testing. Add this to the industry standard goggle mirrors, and you have the strongest offering available.
The Interacoustics digital light bar (DLB) is offered as an option for your VNG system. The DLB functions as a portable alternative to the video projector or flat panel LCD screen, for generating the stimuli for oculomotor testing.
A DLB tripod allows portability, and enables both vertical and horizontal stimulus displays. The DLB’s height above the floor must be at the same level as the patient’s eyes, which is achieved by adjusting the height of the tripod to match the patient’s eye level.
Our VN415 module is designed for convenient computer aided analysis of positional and caloric testing, featuring rapid data transfer technology to enable high quality video and precise measurements, with all results stored in our 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.
Performs real time analysis with rapid data transfer (105Hz binocular, 174Hz monocular) which allows much more data to be analysed, giving very precise measurements.
Our VO425 software module is designed for clinics that carry out detailed balance evaluations, containing all the features of the VN415 plus computer aided analysis of oculomotor tests.
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 a choice of several default and imported patterns.
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.
