The aim of this study is to evaluate whether increased visual dependence can be identified with the help of Virtual Reality (VR). Increased visual dependence is a general term for patients with increased dependence on vision in maintaining their balance. Patients suffering from persistent postural perceptual vertigo (PPPD) often suffer from increased visual dependence. This in turn leads to complaints such as visual vertigo, agoraphobia and fear of falling. Visual dependence is normally measured using the optokinetic after nystagmus (OKAN) and the rod and disc test (RDT). In this study, these two tests are performed with the aid of Virtual Reality.
