Abstract

Subjective Visual Vertical (SVV) tests are used by othoneurologists to assess the visual vertical perception of the subject and/or its eventually impaired performances and functional dysfunctions. In the study of equilibrium system, especially in vertigo or dizziness affected patients, SVV assessment is the only available tool to evaluate interactions between oculomotor subsystem and maculae. In spite of the importance of the test, devices currently used to perform it are quite obsolete; even worse measures can be obtained only looking at the bar and are affected by reading errors. We developed a new device that allow to perform the test in a simpler way and which is able to give the examiner a more precise measurement of the angle under which the subject perceives the vertical. Measures are then sent to a display far away from the patient in order to avoid to give him possible visual references.
