Childhood ocular safety after postnatal exposure to topical dexamethasone during retinopathy of prematurity screening

Acta Ophthalmologica, EarlyView.
Abstract Purpose Dexamethasone eye drops are being introduced off‐label to prevent progression of severe retinopathy of prematurity (ROP). We evaluated ophthalmologic outcomes in early childhood after postnatal topical dexamethasone exposure in pre‐term infants at a standardized follow‐up examination.

Explainable deep learning self‐supervised vision transformer for fundus‐based myopia classification

Acta Ophthalmologica, EarlyView.
Abstract Purpose To develop and validate a self‐supervised vision transformer (ViT) for automated three‐class classification of Normal, High Myopia (HM), and Pathologic Myopia (PM) from colour fundus photographs, with anatomically faithful interpretability. Methods A DINOv2 self‐supervised ViT was fine‐tuned using a two‐stage transfer‐learning protocol

Towards binocular active vision in a robot head system [PDF]

, 2008
This paper presents the first results of an investigation and pilot study into an active, binocular vision system that combines binocular vergence, object recognition and attention control in a unified framework.

The Role of Binocular Disparity in Rapid Scene and Pattern Recognition

i-Perception, 2013
We investigated the contribution of binocular disparity to the rapid recognition of scenes and simpler spatial patterns using a paradigm combining backward masked stimulus presentation and short-term match-to-sample recognition.

Lamination of primary visual cortex in the macaque: Layer 5 subdivisions

Journal of Anatomy, EarlyView.
We show a previously unrecognized trilaminar cytoarchitectonic organization within layer 5 of the opercular portion of the macaque primary visual cortex (V1), denoted as sub‐laminae 5Aα, 5Aβ, and 5B, a region which is involved in foveal and central visual field analyses.

A Single Mechanism Can Account for Human Perception of Depth in Mixed Correlation Random Dot Stereograms.

PLoS Computational Biology, 2016
In order to extract retinal disparity from a visual scene, the brain must match corresponding points in the left and right retinae. This computationally demanding task is known as the stereo correspondence problem.

Intraspecific Variation in Reproductive Aspects of Female Soldier Crabs, Mictyris guinotae, Between the River Mouth and Upper Reach Habitats

Marine Ecology, EarlyView.
ABSTRACT The soldier crab, Mictyris guinotae, is a dominant intertidal crustacean associated with sand flats in the vicinity of the Urauchi River estuary on Iriomote Island, Japan. We compared various aspects of its reproductive biology at two sites (the river mouth and upper reach) on exposed bare sand flats 300 m and 3000 m upstream from the mouth ...

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

, 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.

On the disparity gradient limit for binocular fusion [PDF]

Perception & Psychophysics, 1985
Recently, Burt and Julesz (1980) have measured the limits of single versus double vision (diplopia) in binocular stereopsis. They found that the extent of the fusional limits is not fixed spatially and argued that a limit on the disparity gradient, rather than the absolute disparity magnitude usually associated with the notion of Panum' s fusional area,

Effects of binocular disparity on impressions [PDF]

Japanese Psychological Research, 2012
AbstractWe examined how the size of binocular disparity, which determines the apparent depth magnitude, affects the impressions in different dimensions in viewing nonrepresentational stereograms and representational stereoscopic pictures by the use of semantic differential method with the scales that are related to the basic dimensions of impression ...
