Smooth pursuit eye movements (SPEMs) and saccadic eye movements are both commonly impaired following sport-related concussion (SRC). Typical oculomotor assessments measure individual eye movements in a series of restrictive tests designed to isolate features such as response times.

Calculate point-to-point velocities for each point in the . eye position array . Mark all valid points as unclassified. In this paper, we propose a novel segmentation and clusteri ng-based identification algorithm (I-SC) to effectively recognize fixations, saccades and smooth pursuits in eye tracking. In the proposed algorithm, firstly we employ the velocity feature in the recorded eye data to identify the saccade segments, and then the standard deviation of the dispersion is used to divide the remaining data into segments. The human oculomotor system (HOS) primarily exhibits six eye movement types: fixations, saccades, smooth pursuits (SPs), optokinetic reflex, vestibulo-ocular reflex, and vergence (Leigh & Zee, 2006 ). Among those eye movement types, fixations, saccades, and SPs are most frequently studied.

As studies have suggested that smooth pursuits and saccades share overlapping neural pathways, 35, 36 it may be important for future studies to examine the clinical utility of the smooth pursuit

Smooth pursuit eye movements (SPEMs) and saccadic eye movements are both commonly impaired following sport-related concussion (SRC). Typical oculomotor assessments measure individual eye movements in a series of restrictive tests designed to isolate features such as response times. Smooth pursuits allow visual tracking of a moving item while saccades allow synchronized, rapid eye movement between two or more given points such as in visual scanning. Impaired Saccades.

Saccades and smooth pursuits are the two parts of eye teaming. Smooth pursuits allow visual tracking of a moving item while saccades allow synchronized, rapid eye movement between two or more given points such as in visual scanning.

i “So much has been written about nystagmus that there are only two unresolved questions about nystagmus: 1) the origin of the slow phase, and 2) the Smooth pursuit and saccades are two components of oculomotor control.

A cross-sectional investigation into strabismus, versions/ductions, saccades, smooth pursuit movements and ptosis was performed on 49

Pursuit differs from the vestibulo-ocular reflex , which only occurs during movements of the head and serves to stabilize gaze on a stationary object.

exhibits six eye movement types: fixations, saccades, smooth pursuits, optokinetic reflex, vestibulo-ocular reflex, and vergence [1]. Among those eye movement types fixations, saccades, and smooth pursuit are most frequently studied. The following brief definitions can be provided for these eye movement types: eye

is able to reliably separate ﬁxations, saccades, and smooth pur-suits in an online fashion, even for low-resolution eye trackers. The proposed algorithm is evaluated on four datasets with distinct mixtures of eye movements, including ﬁxations, saccades, as well as straight and circular smooth pursuits; data was collected with Video 1: Smooth Pursuits Vertical and Horizontal (easiest) If you have prescription lenses, you should have the patient wear them. Hold visual target (eg. popsicle stick with letter or shape drawn on the end that can be easily kept in focus) with arm fully outstretched.

3:28Visual Analog Scale, Body Sway and Visual Verbal Learning Test. 5:32Results: av B Kähärä · 2020 — As stated earlier, the essential models in eye movement are saccades, smooth pursuits and fixations. The main task is to detect when one of these models is. Wideness, Pursuit, Velocity and Optokinetic Nystagmus [OKN]) to evaluate both smooth and saccadic movement in different directions. 40 healthy volunteers may be comprised of more than one fixation and saccades to and from it.
