The observation, using an infrared video system, of patients' eye movements resulting from vestibular stimulations and their comparison with electronystagmographic data.

An infrared video technique is presented for the observation and documentation of patients' eye movements during vestibular stimulations in total darkness. Results from the comparison of the video and electronystagmographic information indicate that the infrared video technique is a useful diagnostic aid for vestibular evaluation and in some instances may be necessary. Further, the data from two-channel electronystagmographic recordings may be misleading even when the patient is tested in total darkness with eyes open.
