An attempt to treat ocular flutter and opsoclonus by cerebellar magnetic stimulation

Published:October 04, 2018DOI:
      Ocular flutter (OF) involves abnormal intermittent bursts of horizontal saccades without intersaccadic intervals. Similar saccadic bursts are called opsoclonus (OC) when they follow a horizontal, vertical, and torsional direction. OF and OC are considered to be similar pathologic conditions [

      ]. The causes of OF/OC vary and include parainfectious cerebellar/brainstem encephalitis, paraneoplastic syndrome, metabolic/toxic state, and idiopathic conditions. OF/OC causes oscillopsia, blurred vision, dizziness, and disequilibrium. Immunotherapies, such as intravenous immunoglobulins and corticosteroids, may be effective for OF/OC [

      ]. However, despite these therapies, some cases may be refractory and persistent.
