Abstract
By the use of amplifiers capable of recording very slow potential variations (Offner type 142 DC amplifiers) eyeball movements were recorded. The eyeball maintains a steady potential difference of approximately 500 to 800 microvolts as a result of the electrical polarizing properties of the retina. The amplitude of recorded potential is a direct function of the angle of eyeball deviation from its rest position. In paralysis of movement no potential is recordable; with decreased eyeball movement the recorded potential is decreased proportionately. The clinically important data of rate, deviation angle and absolute direction of gaze can be determined with precision. The use of the method is exemplified in cases showing peripheral and central nervous system lesions involving the eyeball movers.Keywords
