Do standard optometric measures predict binocular coordination during reading?

open access: yesJournal 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.

Error Correction in Vergence Eye Movements: Evidence Supporting Hering’s Law

open access: yesJournal 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 ...

Attentional Selection Accompanied by Eye Vergence as Revealed by Event-Related Brain Potentials. [PDF]

open access: yesPLoS 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.

A covered eye fails to follow an object moving in depth

open access: yesScientific 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 ...

Symptomatic vergence disorders in junior high school children in Ghana

open access: yesAfrican 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 ...

Characterizing Refractive Errors, Near Accommodative and Vergence Anomalies and Symptoms in an Optometry Clinic

open access: yesBritish and Irish Orthoptic Journal, 2022
Background: Refractive, accommodative and vergence parameters and associated anomalies cause symptoms of asthenopia. Patients consult eye care practitioners mainly due to symptoms they experience. To enhance targeted treatments from various anomalies, it
