Effects of virtual target size, position, and parallax on vergence-accommodation conflict as estimated by actual gaze

open access: yesScientific Reports, 2022
Due to the increased utilization of stereoscopic displays, the scope of the vergence–accommodation conflict has been studied extensively to reveal how the human visual system operates.

Large-scale cortico-cerebellar computations for horizontal and vertical vergence in humans

open access: yesScientific Reports, 2022
Horizontal and vertical vergence eye movements play a central role in binocular coordination. Neurophysiological studies suggest that cortical and subcortical regions in animals and humans are involved in horizontal vergence.

Saccades and vergence performance in a population of children with vertigo and clinically assessed abnormal vergence capabilities. [PDF]

open access: yesPLoS ONE, 2011
PURPOSE: Early studies reported some abnormalities in saccade and vergence eye movements in children with vertigo and vergence deficiencies. The purpose of this study was to further examine saccade and vergence performance in a population of 44 children (

Bidirectional Synergistic Vergence [PDF]

open access: yesNeuro-Ophthalmology, 2015
A 14-year-old boy presented with left ptosis and squint since his childhood. In primary position he had left hypotropia with ptosis (levator function 2 mm). With elevation of the right eye, the left eye depresses and adducts; with depression of the right eye, the left eye elevates and abducts. Forced duction test revealed no restrictive pattern.

Vergence fusion sustaining oscillations

open access: yesJournal of Eye Movement Research, 2021
Introduction:  Previous studies have shown that the slow, or fusion sustaining, component of disparity vergence contains oscillatory behavior.  Given the delays in disparity vergence control, a feedback control system would be expected to exhibit oscillations following the initial transient period.

Central crosstalk for somatic tinnitus: abnormal vergence eye movements. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: Frequent oulomotricity problems with orthoptic testing were reported in patients with tinnitus. This study examines with objective recordings vergence eye movements in patients with somatic tinnitus patients with ability to modify their ...

Atypical cognitive vergence responses in children with attention deficit hyperactivity disorder but not with autism spectrum disorder in a facial emotion recognition task

open access: yesPsychiatry Research Communications, 2022
Background: Facial expression of emotion is fundamental to human social interactions. Attention to relevant cues in ADHD and ASD patients are believed to underlie difficulties in recognizing emotions. Cognitive vergence eye movements during gaze fixation

Accuracy of formulae for secondary intraocular lens power calculations in pediatric aphakia

open access: yesJournal of Current Ophthalmology, 2017
Purpose: To compare the accuracy of axial length vergence formulas versus refractive vergence formulas for secondary intraocular lens (IOL) implantation in pediatric aphakia. Methods: This retrospective comparative study, evaluated 31 eyes of 31 patients

Benefits from vergence rehabilitation: evidence for improvement of reading saccades and fixations

open access: yesFrontiers in Integrative Neuroscience, 2016
We hypothesize that binocular coordination of saccades is based on continuous neuroplasticity involving interactions of saccades and vergence. To test this hypothesis we study reading saccades in young students who were diagnosed for vergence disorders ...

Differentiation between vergence and saccadic functional activity within the human frontal eye fields and midbrain revealed through fMRI. [PDF]

open access: yesPLoS ONE, 2011
Eye movement research has traditionally studied solely saccade and/or vergence eye movements by isolating these systems within a laboratory setting. While the neural correlates of saccadic eye movements are established, few studies have quantified the ...
