Exam Preview for 34051: Utilization of the ICS Impulse for Oculomot

Utilization of the ICS Impulse for Oculomotor Assessment in Videonystagmography

Please note: exam questions are subject to change.

1. 1.What is the most relevant difference between oculomotor testing with the ICS ChartR vs ICS Impulse? ICS Impulse only allows for monocular recording of eye movements Caloric testing can only be performed with the ICS ChartR system The ICS impulse offers a more comprehensive test protocol All of the above
2. 2.Oculomotor tests are essential to detect _________ of the oculomotor system and/or vestibular ocular system. Peripheral impairment Central impairment Peripheral and Central Impairment None of the above
3. 3.Why is examination of the eyes important in patients with balance disorder? Subtle ocular motility abnormalities can be detected reflecting the effect of the balance disorder on the ocular system due to its intricate connections with the vestibular apparatus. In many balance disorders the ENT and neurological evaluations are inconclusive and imaging studies are excessive in the initial phases. Ocular movements provide the clinician with information regarding the differential diagnosis related to the balance disorder and provide information regarding the best way for medical and surgical treatment. All of the above
4. 4.Which of the following oculomotor assessments are not included in the traditional VNG protocol? Saccades Tracking VVOR None of the above
5. 5.Which oculomotor tests use different voluntary types of eye movements as a measure of visual-motor responses? Positional, Gaze and Headshake tests Tracking, Saccades and Optokinetic tests VVOR, VORS and Saccades None of the above
6. 6.What do we call the combination of Tracking, Optokinetic, fixation and vestibulo-ocular reflexes Vestibulo-ocular reflex (VOR) Visually enhanced vestibulo-ocular reflex (VVOR) Vestibulo-ocular reflex suppression (VORS) Oculomotor test battery
7. Abnormal VOR suppression is associated with abnormal Tracking Optokinetic Tests Fixation None of the above
8. What is the main difference between saccades and smooth pursuit? Saccades are primarily directed towards moving targets whereas smooth pursuit is elicited when focusing on a stationary target Both saccades and smooth pursuit is directed towards tracking moving targets in the environment to prevent falls Saccades are primarily directed towards stationary targets whereas smooth pursuit is elicited to track moving targets None of the above
9. What feature is available with ICS Impulse that is not available in ICS ChartR? Video playback of eye movements Slow motion playback of video image SPV graphs to analyse nystagmus A and B above
10. What is the most common oculomotor abnormality observed in patients with dizziness? Spontaneous nystagmus Torsional nystagmus Direction changing nystagmus Gaze nystagmus
