Vertigo is one of most common complaints among emergency department patients. It is most important to check the nystagmus when emergency doctors see patients with vertigo. However, there are many cases where we cannot make any diagnosis in the otorhinolaryngological clinic the day following a patient's vertigo attack because the nystagmus has already vanished. In order to resolve this medical problem, we developed a novel method that could record nystagmus anywhere and anytime. This system is very easy for any doctor to record and save the nystagmus in the dark. As a result, we have been able to make a true diagnosis even if patients had nystagmus transiently. We expect that this recording system may lead in the future to a more fulfilling medical practice in the case of patients with vertigo.
