Oscillopsia (Shaky Vision): Causes, Symptoms and Treatment

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. Oscillopsia is an incapacitating condition experienced by many patients with neurological disorders. It may be the result of ocular instability occurring after the oculomotor system is affected, no longer holding images steady on the retina. A change in the magnitude of the vestibulo-ocular reflex due to vesti… WebOscillopsia could also theoretically result from a deficit in mechanisms underpinning perceptual stability maintenance despite constant gaze displacement in the environment.
