A case of post-viral ocular microflutter
Reviewed by Claire Howard

A number of eye movements disrupt visual fixation, one such movement being saccadic intrusions which are described as small involuntary saccadic movements. Among saccadic intrusions without intersaccadic intervals, ocular flutter and opsoclonus are prominent. When the saccadic amplitude is very small, this is referred to as ocular microflutter. The authors present a single case of acute onset oscillopsia following a non-specific viral condition. An ocular microflutter was detected using video-oculography and a diagnosis of isolated idiopathic ocular microflutter was made after extensive investigations. Over several months the condition showed progressive improvement but did not fully resolve. The authors suggest the use of video-oculography where this condition is suspected as it cannot be seen clinically due to its very small amplitude.
