    This study reports three cases of spontaneous saccadic ocular movements, including ocular flutter and opsoclonus. Clinical and electrooculographic data suggest a unified perspective on these related eye movement disorders.

    Area of Science:

    • Neurology
    • Ophthalmology
    • Neurophysiology

    Background:

    • Spontaneous saccadic ocular movements, such as ocular flutter and opsoclonus, are rare neurological phenomena.
    • Understanding their underlying pathophysiology and potential etiological links is crucial for diagnosis and management.

    Observation:

    • Three distinct cases of spontaneous saccadic ocular movements were documented with electrooculographic recordings.
    • Case 1 presented with ocular flutter during myoclonic encephalitis and cerebellar signs.
    • Case 2 involved ocular flutter secondary to acute inflammatory polyneuropathy with cerebellar signs post-cytomegalovirus infection.
    • Case 3 exhibited a progression from dissociated opsoclonus to conjugated opsoclonus and vertical flutter in a patient with bronchial carcinoma.

    Findings:

    Related Experiment Videos

    • Electrooculography provided detailed recordings of the abnormal eye movements in all three cases.
    • The observed movement patterns, despite variations, share commonalities in their neurophysiological basis.
    • Etiological factors ranged from infectious and inflammatory processes to malignancy.

    Implications:

    • The findings support a unified etiological and clinical perspective on flutter-opsoclonus, despite current definitional ambiguities.
    • Further research into the neurophysiological underpinnings of these disorders is warranted.
    • Recognizing the spectrum of spontaneous saccadic ocular movements aids in diagnosing associated neurological conditions.
