Exploring the Impact of Refractive and Ocular Residual Astigmatism on Stereopsis After Photorefractive Keratectomy in Patients With Myopic Astigmatism. [PDF]

open access: yesJ Ophthalmol
Background To investigate the impact of refractive and ocular residual astigmatism (ORA) on stereopsis after photorefractive keratectomy (PRK) for the correction of myopic astigmatism. Methods This prospective observational study was conducted on patients who underwent PRK for the treatment of myopia and myopic astigmatism using a Schwind Amaris 1050RS

Cognitive functions and stereopsis in patients with Parkinson's disease and Alzheimer's disease using 3-dimensional television: a case controlled trial. [PDF]

open access: yesPLoS ONE, 2015
Stereopsis or depth perception is an awareness of the distances of objects from the observer, and binocular disparity is a necessary component of recognizing objects through stereopsis.

A laminar cortical model of stereopsis and 3D surface perception: Closure and da Vinci stereopsis [PDF]

open access: yes, 2004
A laminar cortical model of stereopsis and 3D surface perception is developed and simulated. The model describes how monocular and binocular oriented filtering interact with later stages of 3D boundary formation and surface filling-in in the LGN and ...

The development of a free stereopsis test for active shutter displays [PDF]

open access: yes, 2013
While many people enjoy S-3D, it is a well-known fact that a minority of the population is not able to perceive S-3D. These people have problems with stereopsis, or the ability of our brain to unconsciously fuse two 2D images into a single 3D percept. In

Monocular blur alters the tuning characteristics of stereopsis for spatial frequency and size [PDF]

open access: yesRoyal Society Open Science, 2016
Our sense of depth perception is mediated by spatial filters at different scales in the visual brain; low spatial frequency channels provide the basis for coarse stereopsis, whereas high spatial frequency channels provide for fine stereopsis.
