Videonystagmographie

The VNG is a diagnostic method that is used by recording eye movements of the differential diagnosis of balance disorders. By transmitting information from the labyrinth through the vestibular nerve (vestibulocochlear nerve) to core areas in the brain stem and ultimately the eye muscles this reflex enables postural regulation, gaze stabilization and orientation in space. In case of malfunction of the system can cause impairment of balance and dizziness (vertigo). Whit patients ataxia, vegetative symptoms (nausea) or disturbance of gaze stabilization (Nystagmus) can be seen. This Nystagmus is registered using the VNG. Depending on the direction or type of nystagmus is obtained information about the cause and location of the damage to the equilibrium system
