Wavy patterns in the visual field or the illusion of movement of an object known to be stationary. Oscillopsia can occur so quickly that it feels like an instant of blurry vision. This is commonly caused by retinal slip during head motion in patients with impaired vestibulo-ocular reflex. May occur at rest due to spontaneous nystagmus. In severe cases, may occur from chewing food or with cardiac pulsation. Likely to resolve with vestibular rehabilitation and central compensation for vestibular injury, but may still be present with high-speed or unpredictable head motions due to the limits of central compensation. Oscillopsia that occurs in BPPV testing positions is a positive symptom of BPPV.
