Dynamic Visual Acuity testing assesses VOR function and central processing; poor performance implies what?

• A. Visual acuity unaffected
• B. Peripheral hearing loss
• C. Deficient VOR or impaired central adaptation
• D. Normal VOR with ocular motor palsy

Answer: (C)

Dynamic Visual Acuity testing checks how well you can see clearly when your head is moving, which depends on the vestibulo-ocular reflex to stabilize the gaze and on the brain’s ability to process and adapt that stabilization. If performance is poor, it points to a problem with the reflex itself or with the central processing that tunes and maintains gaze during movement. In practical terms, a reduced dynamic acuity means either the VOR isn’t providing enough gaze stabilization (deficient VOR function) or the brain’s adaptive mechanisms aren’t compensating properly (impaired central adaptation). It doesn’t reflect peripheral hearing status, and maintaining normal visual precision during movement would not explain poor results.
