Quantifying the Natural History of Postinfectious Ocular Flutter

Ocular flutter is a rare ocular oscillation which consists of bursts of involuntary conjugate rapid horizontal eye movements without an intersaccadic interval and is frequently associated with truncal ataxia. It is proposed to be caused by lesions in omnipause neurons or cerebellar vermal pause neurons [1]. Etiologies are varied and include vascular, inherited disorders, paraneoplastic, demyelinating, auto-immune, and postinfectious. In the postinfectious case, resolution is spontaneous though various treatments may speed up recovery [2]. Because a quantified natural history of ocular flutter has not been presented in detail, we present a time series data of postinfectious ocular flutter to aid in clinical management.
