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 [
[1]
]. 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 [
[1]
]. However, despite these therapies, some cases may be refractory and persistent.Keywords
