At the Western Section meeting of the Triologic Society in Santa Barbara, Calif, during January 1991, three physicians from the University of Erlangen, Germany, presented their experience with a new telemetric electronystagmographic system. Drs Stephen R. Wolf, P. Christ, and C. T. Hard have developed a portable recorder similar to a Holter-electrocardiographic monitor, with the data stored digitally and analyzed with a personal computer. Two types of "ski" goggles are modified with preinstalled electrodes that make contact at the appropriate sites for recording eye movements. One goggle is for the patient's use, and the second, with Frenzel's lenses and/or darkened lenses, is used in the clinic to simultaneously view the eyes and to record data. The ambulatory use of such equipment is felt by the authors to be advantageous in that recordings can be made during attacks of vertigo and that the equipment can be a low-cost, compact, time-sparing alternative
