Smooth pursuit gain increased from 0.63 in children aged 5-8 years old to 0.85 in children aged 15-17 years (P = 0.0001). The percentage of gain asymmetry was significantly different in the youngest two groups. Conclusion: Saccade latency decreased as age increased. Smooth pursuit gains increased with increased age.

BackgroundMultiple sclerosis (MS) is a diffuse disease that disrupts wide-ranging cerebral networks. The control of saccades and smooth pursuit are similarly dependent upon widespread networks, with the assessment of pursuit offering an opportunity to examine feedback regulation. We sought to characterize pursuit deficits in MS and to examine their relationship with disease duration

The smooth-pursuit eye-tracking test is useful in evaluating drug toxicity, central nervous system tumors, posterior or middle cerebral artery thrombosis, enceph alitis, whiplash injury, and parkinsonism [3]. Both tests (saccades and eye-tracking) are rarely pathological in peripheral vestibular damage. Based on these observations, some investigators have suggested that the fixation suppression test is a test of the smooth pursuit system and nothing more (Barnes, Benson, and Prior, 1978). If so, the fixation suppression test is redundant because the pursuit function is tested in two other tests within the ENG test battery: the tracking and optokinetic tests.

Utveckling Om upphävd fixationsreflex - vestibulärt test. Om bevarad fixationsreflex istället ett test av följerörelsesystemet. The system must capture and evaluate the smooth pursuit of an individual's eye movement mechanism and log the data for further analysis and evaluation. (2) Central ocular motor signs, such as saccadic smooth pursuit, additional internuclear (3) Further, a pathological SVV deviation by monocular testing of the av S Jansson · 2015 — Dessa tester spelades även in för en demo During execution of these tests the authors discussed on Smooth pursuit är en annan mycket viktig funktion.

Smooth pursuit Maintains gaze stabilization when rate of eye movement is < 60d/sec, i.e. slower then VOR Gain testing Hold the patient’s head stationary. Have the patient follow your slowly moving finger horizontally (from center to 30 degrees right and then to 30 degrees left), and then vertically (center to 30 degrees up to 30 degrees down).

Methods of producing a smooth pursuit target. The smooth-pursuit test (also known as sinusoidal or oscillating tracking) is performed with the patient seated in front of a light bar. The patient is asked to “follow the lights” while holding their head perfectly still. VNG Test for Smooth Pursuit The smooth pursuit tracking VNG tests are also in the oculomotor battery as part of the videonystagmography (VNG) exam. Here balanceback™ tests if the patient can maintain a stable gaze upon objects that are moving within their visual field. We allow the patient to focus upon an object, then blur the background.

Sixty MS patients and 50 volunteers underwent clinical bedside examination and EOG evaluation in a tertiary referral university hospital. EOG recordings of smooth pursuit tests with 0.3, 0.4, 0.5 and 15 Hz amplitude and gain calculation were preformed.

All participants were tested using Rashbass’ step–ramp paradigm of smooth pursuit at constant velocity . At the time of testing, no CIS or CDMS patients were suffering from exacerbated symptomatology or demonstrated any evidence of active disease, and all participants had adequate visual acuity to perform the task.

Finally, Experiment 4 tests the 19 Mar 2013 Smooth-pursuit eye movements allow primates to track moving objects. in patients using a new technique to test these cognitive controls. Methods: Twelve patients treated at the Department of Otolaryngology at our hospital underwent SPEM testing using both electronystamography (ENG) and VOG. Biological Signals Acquisition. EOG tests > smooth pursuit. Humans and other primates can follow a moving visual target of interest by generating voluntary Smooth pursuit (SP) means foveal tracking of a small moving target.
