A LabVIEW program to obtain the initiating component of a vergence eye movement in an open-loop experiment
The vergence oculomotor system is used in viewing objects moving in depth, such as when a baseball player tracks a ball moving towards him. It is composed of two components according to the Dual Mode Theory; a fast preprogrammed initiating component and a slow feedback-controlled sustaining …

A multimodal investigation in eye movements
… interest (ROIs) are functionally active during a vergence movement (inward or outward eye rotation), task-modulated coactivation between ROIs is less understood. This study tests the following hypotheses: (1) significant task-modulated coactivation would be observed between the frontal eye fields …

Short term modification of vergence ramp eye movements in the convergent direction
… various effects of short-term modification on vergence, saccadic and smooth pursuit eye movements. Previous vergence studies have concentrated on step modification stimuli. Few have investigated the effects of short-term modification on vergence ramp movements. Thus, this study explores the …

The effect of vergence vision training on binocularly normal subjects
Vergence is the disjunctive (inward or outward) movement of the eyes that is stimulated by retinal disparity (difference of where an image is projected to the retina and the fovea). A recent randomized clinical trial showed the efficacy of vision therapy for children with the binocular dysfunction …

Cortical location of saccadic and vergence oculomotor learning using fMRI
… about the external world via the visual system. Eye movements are used to direct the visual information of interest to the fovea, the area of the retina which has the highest density of photoreceptors, and the largest amount of cortical area. This research will study how two of the five eye …

A quantitative analysis of eye movement characteristics during the cover test
… to provide a quantitative analysis of the eye movements during the test. There is also a dearth of information concerning the relationship between eye movements during the cover test and symptomatology and the correlation between cover test results and the outcome of other tests of …

Are you looking at me? About the perception of direct gaze and gaze direction
… on the meaning of horizontal and vertical eye movements for the perception of direct gaze. The present dissertation extends this view on the role of vergence eye movements and the angle kappa, i.e., the deviation of the pupillary from the foveal axis, since they influence the visible pupil …
