Fixation instability, astigmatism, and lack of stereopsis as factors impeding recovery of binocular balance in amblyopia following binocular therapy

open access: yesScientific Reports, 2022
Dichoptic therapy is a promising method for improving vision in pediatric and adult patients with amblyopia. However, a systematic understanding about changes in specific visual functions and substantial variation of effect among patients is lacking ...

Rotation and translation effects on stereoscopic acuity [PDF]

open access: yesVision Research, 1975
This study examined the effects of rotation or translation on the detectability of a dotted target plane embedded in a dotted masking cube. Julesz-type stereograms were generated in real time, using a small laboratory computer. Subjects displayed an excellent ability to compensate for x-y projected density variations produced by changes in the angle of

Two independent mechanisms for motion-in-depth perception : evidence from individual differences [PDF]

open access: yes, 2010
Our forward-facing eyes allow us the advantage of binocular visual information: using the tiny differences between right and left eye views to learn about depth and location in three dimensions.

Stereopsis in end-stage renal disease (ESRD) [PDF]

open access: yes, 2017
We investigated an effect of end-stage renal disease (ESRD) on the visual system by measuring the ability of 21 patients to perceive depth in the random dot stereograms and circles of the Randot Test.

Visual acuity response when using the 3D head-up display in the presence of an accommodation-convergence conflict

open access: yesJournal of Information Display, 2020
Visual discomfort and fatigue due to accommodation-convergence (AC) conflict in stereoscopic displays has been widely reported, but little is known about its impact on visual acuity, particularly when automotive three-dimensional (3D) head-up displays ...

Stereoacuity after photorefractive keratectomy in myopia

open access: yesJournal of Current Ophthalmology, 2016
Purpose: Stereopsis, as a part of visual function, is the ability of differentiating between the two eyes' views (binocular disparity), due to the eyes' different positions.
