Results: There were differences and similarities between the low vision clinics and how (26) Strabismus is frequently seen as well as disturbances of smooth pursuit eye It is therefore often necessary to use unorthodox tests and behavioral

Smooth pursuit eye movement. This experiment focuses on the effect of visual motion direction (leftward and rightward) on smooth pursuit initiation. Figure 1 shows representative eye velocity and acceleration traces during step‐ramp tracking (ramp velocity = 18.5 deg/sec) to the leftward and rightward directions.

Variance measures the deviance of a gaze path from the ideal path of a stimulus; a smaller spread of gaze positions around the target path indicates better accuracy [22]. SP% deﬁnes the amount of time spent performing a smooth pursuit with appropriate dispersion and slight disturbances in the Romberg test, the finger-nose test, diadochokinesis, and the walking test. On the basis of our knowledge of aminoglycoside's negative influ ence on Purkinje cells, we postulated a cerebellar corti cal lesion in all cases.

In the smooth pursuit eye movement test: a stimu-lus for the test is a light target moving in a sinusoidal pat-tern including 3 cycles of each the following frequencies 2,3,4,5,6,7 Hz in a 34 degree screen. The amplitude of the movement is 16.7 degrees. Once completed, the se-

Drugs causing lack of smooth pursuit include depressants, some inhalants, and dissociative anesthetics (such as phencyclidine or ketamine). This video tutorial provides a description of how the smooth pursuit test is performed and a short summary of results interpretation.

2020-01-23 · In our most recent webinar, we sat down with our CCO Scott Anderson, to review the Smooth Pursuit assessment. During this presentation, Scott explained what EYE-SYNC users should know, what to should look for, and how to get the most out of what the results are telling us. As part of testing the central (brain) vestibular system, a series of tests are performed, including smooth pursuit, saccades and optokinetic nystagmus (OPK) Interpretation of Oculomotor Tests • Tests of oculomotor function (with fixation) – Saccade (fast eye movements) – Tracking (slow voluntary eye movements) – Optokinetic (reflexive eye movements but the test performed as a part of ENG/VNG using a light bar is not a true test of optokinetic pathways) Smooth pursuit engages several cognitive processes including attention, decision-making, and prediction or preparation (Barnes 2008; Ferrera and Lisberger 1995, 1997b; Knox and Bekkour 2002).

SMOOTH PURSUIT NECK TORSION TEST The smooth pursuit neck torsion (SPNT) test is partly a test of the smooth pursuit (SP) eye movement system and partly a test of the proprioceptors in the neck. The SPNT test is performed as follows: the person sits in neutral position in front of a screen with a red dot moving horizontally to and fro.

During this presentation, Scott explained what EYE-SYNC users should know, what to should look for, and how to get the most out of what the results are telling us. Test smooth pursuit by having the patient follow an object moved across their full range of horizontal and vertical eye movements. Test convergence movements by having the patient fixate on an object as it is moved slowly towards a point right between the patient's eyes.
