25 Possible Causes for Overshooting Horizontal Saccades

  • Myelocerebellar Disorder

    […] wave jerk, consistently undershoot or overshoot the target during horizontal saccadic eye movements (saccadic dysmetria) – ABL -progressive paresis of the medial rectus muscles[slideshare.net] Ocular Motor Functions • Smooth pursuit movements • Saccades • Certain clinical cerebellar syndromes might have characteristic patterns – FRDA1- fixation instability, square[slideshare.net]

  • Foster-Kennedy Syndrome

    Burst cells that initiate horizontal sac-cades are situated within the paramedian pontine reticularformation.[docslide.com.br] […] of the head relative to the target.The reticular activating system contains burst cells thatinitiate saccades.[docslide.com.br] […] became evident, however, that his dimin-ished vestibulo-ocular reflex enabled him to move the eyesand head together, without the need for a head thrust andits associated overshoot[docslide.com.br]

  • Boucher-Neuhauser Syndrome

    Gaze-evoked horizontal nystagmus, cleary ocular saccadic overshot and cerebellar dysartria were also present. The symptoms slightly progressed throughout the years.[scielo.br] There was moderate overshoot on upper limb ballistic tracking movements.[scielo.br]

  • Autosomal Recessive Spinocerebellar Ataxia 8

    […] wave jerk, consistently undershoot or overshoot the target during horizontal saccadic eye movements (saccadic dysmetria) – ABL -progressive paresis of the medial rectus muscles[slideshare.net] Ocular Motor Functions • Smooth pursuit movements • Saccades • Certain clinical cerebellar syndromes might have characteristic patterns – FRDA1- fixation instability, square[slideshare.net]

  • Spinocerebellar Ataxia Type 14

    In other series, Yamashita et al 5 described ocular overshoot (saccadic hypermetria?)[jnnp.bmj.com] […] in three out of nine patients, while Brkanac et al 4 recorded horizontal jerk (gaze evoked) nystagmus or broken-up smooth pursuit in the majority, although it is not clear[jnnp.bmj.com]

  • Spinocerebellar Ataxia Type 26

    Saccadic main sequence of peak velocity of horizontal saccades as a function of the saccade amplitude for the 10 MJD patients plotted on a log-log scale (following Garbutt[iovs.arvojournals.org] In contrast, for 7 of the 10 MJD patients, the mean overshoot is significantly ( P 0.05) larger than 2%.
