Differential diagnosis of vergence and saccade disorders in dyslexia
Scientific Reports, 2020 Previous studies suggest vergence and saccade abnormalities in dyslexic adolescents. However, these studies are mainly clinically based and do not provide objective measurements of eye movements, but rather subjectively evaluate vergence using haplosopic

Error Correction in Vergence Eye Movements: Evidence Supporting Hering’s Law
Journal of Eye Movement Research, 2012 In pure symmetrical vergence eye movements, a fusion initiating component quickly brings the eyes close to the desired position. A small error usually remains after this response which must be corrected to attain the small final vergence error (i.e ...

Stability of vergence accommodation and accommodative vergence assessment
, 2011 International audienceAccommodation and vergence are two components of the oculomotor system that are cross-linked. This interaction is hold by the accommodative vergence (vergence induced by accommodation) and by the vergence accommodation ...

Do standard optometric measures predict binocular coordination during reading?
Journal of Eye Movement Research, 2021 In reading, binocular eye movements are required for optimal visual processing and thus, in case of asthenopia or reading problems, standard orthoptic and optometric routines check individual binocular vision by a variety of tests.

A covered eye fails to follow an object moving in depth
Scientific Reports, 2021 To clearly view approaching objects, the eyes rotate inward (vergence), and the intraocular lenses focus (accommodation). Current ocular control models assume both eyes are driven by unitary vergence and unitary accommodation commands that causally ...

Changes in vergence and accommodation parameters after smartphone use in healthy adults
Indian Journal of Ophthalmology, 2021 Purpose: To assess pre and post vergence and accommodation parameters after monitored reading on a smartphone device. Methods: This prospective comparative study was performed in a tertiary eye care center for a duration of 6 months (December 2017 – May ...

Attentional Selection Accompanied by Eye Vergence as Revealed by Event-Related Brain Potentials. [PDF]
PLoS ONE, 2016 Neural mechanisms of attention allow selective sensory information processing. Top-down deployment of visual-spatial attention is conveyed by cortical feedback connections from frontal regions to lower sensory areas modulating late stimulus responses.

Gaze Dependent Vergence Adaptation.
, 2015 PURPOSE The innervational pattern of extraocular muscles that maintain ocular alignment vary with gaze direction, age, and orbital anatomy. A muscle paresis, for example, may cause a misalignment, which is characterized by a gaze dependent deviation ...

Symptomatic vergence disorders in junior high school children in Ghana
African Vision and Eye Health, 2016 Background: Optometrists in Ghana are hampered in performing comprehensive binocular vision assessments, because of the lack of appropriate instruments leading to a paucity of data on vergence disorders and their association with asthenopia among ...
