The questions on this page refer to Tobener et al, “Oculomotor Findings in Videonystagmography across the Lifespan,” pages 11–18.

Learner Outcomes

Readers of this article should be able to:

• Identify differences in oculomotor findings between children and older adults compared to the control group.

• Describe the effects of aging on the oculomotor test battery.

CEU Questions

1. Why is oculomotor testing included in videonystagmography (VNG) testing?

   • This testing indicates neurological impairment and provides baseline measurement of oculomotor function prior to positional/positioning and caloric irrigation.

   • This testing indicates vestibular nerve function.

   • This testing indicates source of dizziness.

2. Which of the following is not a reason for improvement of oculomotor function in early childhood?

   • attentional maturation

   • brain myelination

   • temporal lobe maturation

3. Which of the following is not a reason for degradation of oculomotor function with aging?

   • decreased neuronal density

   • memory impairment

   • decreased cortical gray matter

4. What oculomotor tests were analyzed?

   • saccades, smooth pursuit, OPK

   • gaze, saccades, OPK

   • smooth pursuit, OPK, spontaneous nystagmus

5. What differences were seen in saccades for both the children and older adults compared to the control group?

   • prolonged latency

   • decreased speed

   • decreased accuracy

6. What trend was observed across groups as the frequency increased in smooth-pursuit testing?

   • Gain increased as frequency increased

   • Gain decreased as frequency increased

   • No change in gain as frequency increased

7. Which speed of optokinetic (OPK) testing revealed no significant difference between groups?

   • 20 degrees/sec

   • 40 degrees/sec

   • 30 degrees/sec

8. What was the overall purpose of this investigation?

   • To establish normative data for oculomotor testing in children

   • To establish normative data for oculomotor testing in older adults

   • To further describe the age effect on oculomotor function

9. What is a possible risk when comparing oculomotor testing results across the lifespan?

   • not having normative data to compare to

   • errors in diagnosing central vestibular involvement

   • equipment malfunction

10. What is the suggested speed for testing smooth pursuit across all groups?

    • 0.6 Hz

    • less than 0.6 Hz

    • greater than 0.6 Hz
