Overview
Oscillopsia is a visual disturbance in which objects in the visual field appear to oscillate. The severity of the effect may range from a mild blurring to rapid and periodic jumping.
Differential diagnosis of causes of Oscillopsia:
Oscillopsia may be caused by loss of the vestibulo-ocular reflex, involuntary eye movements such as nystagmus, or impaired coordination in the visual cortex (especially due to toxins).
Associated signs and symptoms
Sufferers may experience dizziness and nausea. Oscillopsia can also be used as a quantitative test to document aminoglycoside toxicity.
