In order to diagnose the pathological condition of vertiginous patients, a detailed observation of nystagmus in addition to examination of body equilibrium and other neurotological tests are essential. For this purpose, methods for precise observation and analysis of the eye movements have been studied and have been developed up to the present. How to precisely record eye movements has been one of the long-term goals of researchers and clinicians who are interested in the analysis of eye movements. Devices are currently available which can quite accurately record human eye movements, based on the principle of video-oculography (VOG). Improvement of these devices, however, can be expected in the near future along with technological advancement, coupled with further development of the software engines which analyze the recorded movements of the eye in three dimensions, thus improving the accuracy of the measurement and the speed of analysis. We clinicians will then be able to easily record and analyze the eye movements in patients with vertigo and/or disequilibrium. Furthermore, from the data provided by vector analysis of the slow phase of nystagmus, diagnosis of the localization of the disease in the peripheral labyrinth will also be possible.
