Abstract

Tourette syndrome (TS) is a neuropsychiatric disorder that is characterised by the presence of multiple vocal, facial, and motor tics which change with time, and a number of other behavioural phenomena. Previous studies have not revealed any ocular-motor abnormalities. We report the eye movement studies of a patient with TS, using electrooculography and simultaneous video recording. Intrusive saccades occurred during smooth pursuit and optokinetic nystagmus. Reflexive and voluntary saccades were dysmetric and there was a complete failure of antisaccades. These abnormalities are characteristic of disease of the frontal lobes and basal ganglia. We review the literature with respect to the eye movement abnormalities associated with TS.
