Spontaneous nystagmus (video oculography)

Video-oculography shows spontaneous nystagmus beating leftward, upward, and counterclockwise without fixation. H = horizontal position of the left eye, V = vertical position of the left eye, T = torsional position of the left eye. In each recording, upward deflection indicates rightward, upward, and clockwise eye motion. (From: Liqun Z, Park KH, Kim HJ, Lee SU, Choi JY, Kim JS.
