[Comparative study of electrooculographic and photooculographic recordings]

The authors present the results of clinical application of a new invasive real time method for ocular movement recording. There is an optical system which measures the gaze direction from the video signals of five reflected corneal dots and pupil image. Their study is based upon 110 simultaneous P.O.G. - E.O.G. recordings of normal beings or patients having various oculomotor troubles. It appears that the heavy odds of such a new method is obvious. It allows to obtain an absolute measurement of eye positions in relation to the basic line whatever the pattern and axis of the moving may be. A quantitative evaluation of all movement parameters is in progress. It still remains to solve the problem of large deviations and the wearing of optical correction during the examination.
