Figure 1.

Video-oculography showing small-amplitude saccades, mostly DSPs (continuous arrows), during fixation in the left lateral position that consisted of small-amplitude oscillations leftward and rightward during eye movement recording, which were compatible with sawtooth ocular microflutter bursts (with an amplitude of 0.2–1 degrees and an approximate frequency of 15 Hz) (dashed arrow). Note: By convention, rightward and leftward ocular movements are represented by upward and downward tracings in eye movement recordings.
