Description
Static [esotropia] and dynamic [gaze-evoked and optokinetic nystagmus (GEN; OKN), hypometric/hypermetric saccades, low gain pursuit and head impulse (HI)] ocular motor abnormalities (OMA) have all been described in spinocerebellar ataxia type 3 (SCA3). Importantly, dynamic ocular motor abnormalities during eye abduction and adduction are often asymmetric in ataxia. We sought to evaluate the role of static OMA, and abduction vs. adduction dynamic OMA as potential biomarkers in SCA3.
