Summary of vestibulo–ocular reflex (VOR) and visually enhanced VOR (VVOR) values obtained in this study for each group.

Parameters	Healthy	CANVAS	Vestibular bilateral	Vestibular unilateral
Mean gain VOR	Normal (bilateral) 1 ± 0
Mean gain VVOR	Normal (bilateral) 1 ± 0		Mild (bilateral) 0.8 ± 0.1	Moderate (ipsilesional) 0.6 ± 0.1
Saccades per cycle VVOR	0 ± 0	4 ± 2	3 ± 1.6	2 ± 0.8

Mean gain values are presented for VOR, and values of mean gain and saccades per cycle are presented for VVOR. CANVAS, cerebellar ataxia, neuropathy, and vestibular areflexia syndrome.

Red color is used to highlight lowest values on VOR and VVOR gain values.
