This chapter contains some details concerning the electro-oculogram (EOG) as it relates to eye movement, including nystagmus. The collective behavior of the entire retina is a bioelectric generator, which sets up a field in the surrounding volume conductor. This potential field is normally measured between an electrode on the cornea (contact-lens type) and a reference electrode on the forehead. The recorded signal is known as the electroretinogram (ERG). It may be examined both for basic science studies and for clinical diagnostic purposes. The electroretinogram is discussed in this chapter in connection with the electrooculogram to follow the anatomical division of bioelectromagnetism. It is, of course, more practical to discuss all electric signals originating in the eye after the anatomy and physiology of this organ are presented.

Keywords:   electric signals, electro-oculogram, eye movement, nystagmus, retina, electroretinogram
