Introduction: Several methods of testing the subjective visual vertical (SVV) have been described. The aim of this study is the testing of a novel method of SVV. The novel method consists of a goggle preventing any light to enter the goggle. The goggle displays a lightbar which has to be adjusted into the vertical by the patients. Furthermore a sensor measuring the tilt angle is integrated in the goggle.
Patients and Methods: Patients with a peripheral vestibular disorder were examined by the novel method (C-SVV) and the conventional dark room method (D-SVV). The SVV and the head tilt angle were recorded and compared.
Results: Tilt angle of the SVV in C-SVV showed to be slightly more increased than in D-SVV.
Conclusion: The novel method in measuring SVV is a safe and convenient method. The advantage of the C-SVV is the lack of necessity to provide a dark room as it is demanded in D-SVV. Furthermore recording of the head tilt angle can be performed with the C-SVV simultaneously.
