Answer

Answer

Oscillopsia test

  • Before and during vigorous head shaking, the patient is asked to read the smallest visible line on the Snellen eye chart.

  • A normal result is the ability to maintain acuity within 2 lines of the acuity at rest. Oscillopsia is the result of bilateral vestibulopathy, which most commonly is observed in ototoxicity.
