Letter to the Editors

A patient with adult-onset Still’s disease (AOSD)1 developed periodic horizontal micro-saccadic oscillations and periodic rapid clockwise torsional eye movements followed by counterclockwise torsional drifts (see video). Neuroimaging studies were normal. Tests for paraneoplastic antibodies were negative. Details of the clinical presentation and experimental methods are presented in supplementary material 1.

Horizontal saccades were faster than normal (supplementary material 2). There were bursts of horizontal saccadic oscillations without intersaccadic intervals (21.6 ± 0.4 Hz) and clockwise rapid torsional eye movement (top pole rotating towards the right ear) that had the same peak velocity-amplitude relationship as torsional quick phases of nystagmus (Fig.  1). These rapid torsional movements were followed by a drift (0.8 ± 0.2 deg/s) that brought the eyes to baseline. Low-frequency vertical and torsional oscillations were also seen (median: 3.4 and 3.1 Hz, respectively; Fig.  1b,...
