Abstract
-
Electrooculography (EOG or ENG) is the simplest and most readily available diagnostic tool for recording and quantitatively analysing the pathologic nystagmus, visually guided eye movements (saccades, pursuits, OKN) and Vestibular-ocular reflexes. By using our standard method, we analyzed the normal ranges of smooth pursuit velocity and its gain, slow component velocity of OKN, and the bitherrnal caloric response. Our results of ENG tests for normal controls would be used as a basic quantitative data in evaluating vestibular dysfunction, and ocular motility disorders.
