Some remarks on electro-oculography (EOG)
The term electro-oculography has a double meaning. The registered potential difference is dependent on the position of the eye with respect to the attached electrodes and the amount of the potential between the cornea and the retina (corneo-retinal potential CRP or Bestandspotential). The CRP is assumed to be constant during the EOG used as an eye movement recording method. As a clinical test to analyze the function of the retina the EOG requires a constant angle of eye movement.
