SYNAPSYS VNG offers a large range of tests including vestibular and ocular-motor tests.
As of today, SYNAPSYS VNG is the only available system on the market with a wireless camera that grants an unparallel user experience in regard to patient mobility, freedom of movements and flexibility of use. SYNAPSYS VNG is also available with standard wired camera.
SYNAPSYS VNG offers a wide and complete range of tests, including vestibular and oculomotor.
As of today, SYNAPSYS VNG is the only available system on the market with a wireless camera that grants an unparallel user experience in terms of patient mobility, freedom of movement and flexibility of use. SYNAPSYS VNG is also available with standard wired camera and, optionally, a second camera (wireless or wired) can be added to allow binocular recordings.
SYNAPSYS VNG testing modules include: Nystagmus, Caloric, Saccade, Smooth Pursuit, Gaze, Optokinetic, Kinetic and Subjective Visual Virtual. Performing all of these tests has never been easier thanks to the comfort that the ultralightweight goggles offers to both patients and users.
Advanced high-frequency bi-ocular analysis is also optionally available with the Visio Mask. Specifically designed for oculomotor testing, it analyses both eyes simultaneously, allowing a true open field view.
By using state-of-the-art infrared cameras (whether wireless or wired) the patient’s eye movements are recorded by the software and, thanks to its unique eye tracking system, SYNAPSYS VNG instantly detects the pupils without any adjustment required, even when it comes to difficult situations such as dark eyelids.
SYNAPSYS VNG can guide you through the examination of balance disorders and help reduce the time of the testing. The presence of complete normative data with which to compare results, the possibility to insert markers in real time and select different tracking modes (graphs, tables), as well as the available pre-loaded test protocols, make the software extremely reliable and easy to use.
SYNAPSYS VNG is adaptable to all your needs. It is available in two different models, Screening and Standard, and can also be combined with the rotary chair to complete your battery of videonystagmographic tests with rotational kinetic exams. Sixteen stimulation wave forms are available, including various sinewave forms, multi-frequency, speed step and sudden stop tests.
