Purpose:
To describe the clinical presentation and results of three-dimensional video-oculography of a patient with idiopathic microsaccadic opsoclonus.
Design:
Observational case report.
Methods:
Neuro-ophthalmologic examination and video-oculographic recording of horizontal, vertical, and torsional eye movements.
Results:
A 67-year-old man with intermittent blurred vision and oscillopsia, which persisted with monocular occlusion, over a five year period was found to have high frequency, small amplitude back-to-back multivectorial saccadic movements which were visible with slit lamp biomicroscopy and direct ophthalmoscopy. Video-oculography showed a 20 Hz, 0.2 to 1 degree pattern of horizontal, vertical, and torsional microsaccades. This microsaccadic disorder has persisted for five years with no etiology.
Conclusions:
Microsaccadic opsoclonus is an idiopathic disorder that presents with oscillopsia and intermittent blurred vision. The diagnosis can be confirmed with three-dimensional eye movement recordings.
