THE RECORDING of eye movements during the examination of the vestibular system has recently been gaining in popularity in this country. As a result several questions have arisen regarding the clinical application of nystagmography, how such recordings can be fitted into clinical practice, and whether the experienced otoneurologist should conduct the complete examination which, therefore, requires his observation while the recordings are being made.
A review of the methods developed for recording eye movements is presented with comments on the efficacy and limitations of those in more common use. The eye movements of both man and animals have been recorded by well over 100 methods. The principles underlying these procedures, however, can be reduced to a few categories. A summary of numerous techniques can be found in the reviews of Schmidt,1 Grünberg,2 Vernon,3 Wendt and Dodge,4 and Marg.5
