CLINICAL USEFULNESS OF ELECTRONYSTAGMOGRAPHY.

An electrical method for measuring and recording eye motion (electronystagmography) allows greater accuracy and sensitivity than methods previously used. As herein applied to studies of labyrinthine function, measurement of eye speed during caloric-induced nystagmus, as an indicator of pathological spontaneous or positional nystagmus not otherwise observable, or observation of eye motion with the lids closed, demonstrates that the technique is valuable as a clinical tool.
