[Applied nystagmometry in differentiating vesitbular diseases (author's transl)]

Nystagmus as a reaction on vestibular stimulation is influenced by many factors which are difficult to control. One of the most important parameters correlating best with the excitability of the peripheral vestibular apparatus is the speed of the slow phase of the nystagmus. This can be registered directly by use of the nystagmometer (or Blauert System), together with the speed of the fast phase. All parameters of the nystagmus can be easily described when recorded. However, an exact description of the nystagmic reaction should not be considered as a complete diagnosis by itself alone; the diagnosis can only be the result of combining nystagmometry, audiometry and other otoneurological or neurological findings with the patient's presenting complaints (or history of the disease involved).
