During the saccadic eye movement test, patients may report which symptoms?

• A. Dizziness and blurred vision
• B. Numbness in fingers
• C. Hearing loss
• D. Tinnitus in the ears

Answer: (A)

During saccadic eye movement testing the focus is on how quickly and accurately the eyes can jump between targets and how well the brain coordinates eye movements with the vestibular system to keep vision stable. Because these rapid shifts can momentarily disrupt the stable image on the retina and engage the vestibulo-ocular reflex, patients often notice dizziness or a brief blur of vision as the gaze re-stabilizes. Numbness in fingers would point to a somatosensory or neural issue unrelated to eye-movement functions, while hearing loss or tinnitus are auditory symptoms not typically produced by saccadic testing. So dizziness and blurred vision are the symptoms most likely reported.
