Subject recruitment:
The study will be publicized through advertising documents. Written informed consent from the participants will be obtained with explanatory documents.
Methods:
Nystagmus is induced by cold air carolic test.
The slow phase velocity is measured by ENG while observing the nystagmus with a new loupe, Frenzel goggles, and naked eye.
A video of the nystagmus will be simultaneously recorded.
Data Analysis:
Comparison of the slow phase velocities of the three observation methods by Wilcoxon signed rank test.
Evaluation of visibility by video recording.
