Nystagmography

Clear vision requires both eye motion and highly accurate positioning of the fovea. Various types of oculomotor activity are distinguished (e.g., ocular reflexes, fixation, saccade, smooth pursuit). Different methods can be used to record eye movements. The most common methods for clinical application are electronystagmography, photoelectronystagmography, and videooculography. Examples for signal processing and medical significance are given.
