Preoperative binocular vision characteristics in the age-related cataract population

open access: yesBMC Ophthalmology, 2022
Background This study is the first part of the “Binocular Vision Anomalies after Cataract Surgery” study that aimed to investigate the impact of cataract surgery on binocular vision status in adults with age-related cataract.

Research Progress of the Effects of Monocular Visual Impairment on Binocular Vision [PDF]

open access: yesFayixue Zazhi, 2018
Binocular vision refers to a progress of analysing and integrating the binocular visual signals into a whole and three-dimensional sensory perception by higher nerve centre.

Binocular summation of contrast remains intact in strabismic amblyopia [PDF]

open access: yes, 2007
PURPOSE. Strabismic amblyopia is typically associated with several visual deficits, including loss of contrast sensitivity in the amblyopic eye and abnormal binocular vision.

Psychophysical evidence for two routes to suppression before binocular summation of signals in human vision [PDF]

open access: yes, 2007
Visual mechanisms in primary visual cortex are suppressed by the superposition of gratings perpendicular to their preferred orientations. A clear picture of this process is needed to (i) inform functional architecture of image-processing models, (ii ...

Binocular interaction: contrast matching and contrast discrimination are predicted by the same model [PDF]

open access: yes, 2007
How do signals from the 2 eyes combine and interact? Our recent work has challenged earlier schemes in which monocular contrast signals are subject to square-law transduction followed by summation across eyes and binocular gain control.

Binocular combination in abnormal binocular vision

open access: yesJournal of Vision, 2013
We investigated suprathreshold binocular combination in humans with abnormal binocular visual experience early in life. In the first experiment we presented the two eyes with equal but opposite phase shifted sine waves and measured the perceived phase of the cyclopean sine wave.

Cyclopean geometry of binocular vision [PDF]

open access: yesJournal of the Optical Society of America A, 2008
The geometry of binocular projection is analyzed, with reference to the primate visual system. In particular, the effects of coordinated eye movements on the retinal images are investigated. An appropriate oculomotor parameterization is defined, and is shown to complement the classical version and vergence angles.

Binocular coordination: Reading stereoscopic sentences in depth [PDF]

open access: yes, 2012
The present study employs a stereoscopic manipulation to present sentences in three dimensions to subjects as they read for comprehension. Subjects read sentences with (a) no depth cues, (b) a monocular depth cue that implied the sentence loomed out of ...

Intraexaminer repeatability and agreement in stereoacuity measurements made in young adults [PDF]

open access: yesInternational Journal of Ophthalmology, 2015
AIM: To determine the repeatability and agreement of stereoacuity measurements made using some of the most widely used clinical tests: Frisby, TNO, Randot and Titmus.

Robot Obstacle Recognition and Target Tracking Based on Binocular Vision

open access: yesAdvances in Multimedia, 2022
To further improve the perception ability of binocular vision sensor in getting rich environment information and scene depth information, a research method of a robot obstacle recognition and target tracking based on binocular vision was proposed.
