Compared to left sided ST‚ tinnitus perceived on the right side impaired almost all the parameters of saccades (latency‚ amplitude‚ velocity‚ etc.) and noticeably the upward saccades. Relative to controls‚ saccades from both groups were more dysmetric and were characterized by increased saccade disconjugacy (i.e.‚ poor binocular coordination). Although the precise mechanisms linking ST and saccadic control remain unexplained‚ these data suggest that ST can lead to
