Oscillopsia is best described as which of the following?

• A. Tinnitus
• B. Headache
• C. Double vision
• D. Images slipping from the fovea

Answer: (D)

Oscillopsia is the perception that the visual environment is moving, usually because the image isn’t held steadily on the fovea during head or eye movements. When the gaze-stabilizing system (the vestibulo-ocular reflex) fails, the retinal image slips across the retina. Since the fovea is responsible for sharp vision, this slip makes the world appear to slide or oscillate. That’s why “images slipping from the fovea” best describes oscillopsia. Tinnitus and headaches are unrelated sensory symptoms, and diplopia means seeing two images rather than a moving scene—the key feature of oscillopsia is the perception of motion of the entire visual field, not double vision.
