Purpose: To compare the long-term clinical outcomes of patients with refractive accommodative esotropia (RAET) and infantile (IET).Methods: The medical records RAET IET who were followed-up for more than 36 months retrospectively analyzed. prescribed spectacles to correct cycloplegic refraction those underwent bilateral, medial rectus recession. Visual acuity, refraction, angle esodeviation at ...

Little is known about the localization in the brain of fusion of disparate images from each retina to create the sensation of stere­ opsis. One might expect the visual associa­ tion cortex in the parietal lobe to be in­ volved, but information about the effect of parietal lobe damage on stereopsis is scanty. Perhaps the most significant work con­ cerning the localization of stereopsis was that ...

A laminar cortical model of stereopsis and later stages of 3D surface perception is developed and simulated. The model describes how initial stages of monocular and binocular oriented filtering interact with later stages of 3D boundary formation and surface filling-in in the lateral geniculate nucleus and cortical areas V1, V2, and V4. In particular, it details how interactions between layers 4...

The paper discusses the possible use of binocular cues by aircraft pilots in the final landing phase through a review of literature. The review includes medical and psychophysical literature, as well as works on pilot training, certification and flight experiments. It was found that stereopsis can be used as a depth cue up to several hundred meters. However, in situations where monocular cues a...

Monocular acuity and stereopsis were assessed by preferential-looking procedures in untreated infantile esotropes. Results were compared to an age-matched normal population. Monocular PL acuity was not significantly different from normal during months 3-14 for infantile esotropes who freely alternated fixation and for the preferred eyes of unilateral infantile esotropes. PL acuity of the non-pr...

Viewing a real three-dimensional scene or a stereoscopic image with both eyes generates a vivid phenomenal impression of depth known as stereopsis. Numerous reports have highlighted the fact that an impression of stereopsis can be induced in the absence of binocular disparity. A method claimed by Ames (1925) involved altering accommodative (focus) distance while monocularly viewing a picture. T...

Dynamic random dot fusion, stereopsis and stereoacuity were evaluated in 149 healthy, fullterm infants, using both forced-choice preferential looking (FPL) and steady-state visual evoked potential (VEP) protocols. Few infants aged 2-3 months demonstrated fusion or stereopsis in either the FPL or VEP protocol; most infants aged 5 months and older demonstrated fusion and stereopsis in both protoc...
