Test-Retest Reliability and Spatial Tuning of Serial Dependence

Mar 30, 2022

Even when visual information is chaotic and unpredictable, humans see objects and scenes consistently. Serial reliance is one of the processes behind this perceptual constancy. The perception of objec...

Contributed Session II: Visual Search in Virtual Reality (VSVR): A Visual Search Toolbox for Virtual Reality

Mar 29, 2022

Many visual search experiments undertaken over the last several decades have tremendously aided researchers’ knowledge of human visual attention. Task observers with finding a specific goal hidden a...

Contributed Session II: Evidence for a Dipper Effect in the Perception of Global Form: Findings From Psychophysics and EEG

Mar 29, 2022

Decades of psychophysical tests have demonstrated that the perception of low luminance contrast defies Webers' law: contrast discrimination works best at low (but non-zero) pedestal intensities. The "...

Two-Dimensional Shape Perception is Based on a Salience Map

Mar 29, 2022

A salience map is a dynamic topographical map that integrates data from various feature maps to provide a real-number measure of conspicuity (salience). Initially, Koch and Ullman (1985) employed sali...

Tissue Properties of Optic Radiations Representing the Foveal And Peripheral Visual Fields

Mar 29, 2022

The foveal and peripheral visual pathways have very different biological properties. For a study, researchers used diffusion MRI (dMRI) to examine the tissue characteristics of optic radiations (OR) t...

In-Vivo Classification of Human Cone Photoreceptors Reveals Crystalline S-Cone Sub-Mosaics in the Central Retina

Mar 29, 2022

The topography of S-cones in the macula establishes the neuronal limitations for coding the color vision's short-wavelength spectrum. According to the findings, S-cones tile the central human retina w...

What Limits the Spatial Resolution of Artificial Vision in Epiretinal Implant Patients?

Mar 29, 2022

Retinal implants give blind people artificial vision by electrically activating non-photoreceptor retinal cells. Individual electrodes in epiretinal implants placed above the ganglion cell layer creat...

The Effect of Spherical Defocus On Vergence And Diplopia in Adults And Children

Mar 29, 2022

Strabismus or amblyopia can occur in anisometropic children (those with an uneven refractive error in both eyes). To better understand the relationship between anisometropia, vergence eye movements, a...

Distinguishing Mirror From Glass: A “big data” Approach to Material Perception

Mar 29, 2022

Distinguishing a mirror from a glass is a tough visual inference since both materials get their look from their environment, but humans seldom have trouble telling them apart. Little research was cond...

Mapping Spatial Frequency Preferences Across Human Primary Visual Cortex

Mar 29, 2022

Neurons in the primate visual cortex (area V1) are tuned for spatial frequency based on their position in the visual field. Several studies used functional magnetic resonance imaging (fMRI) to investi...

Postural Adjustment As a Function of Scene Orientation

Mar 29, 2022

Although visual orientation is vital in postural regulation, the particular properties of postural response to orientation are unclear. For a study, researchers explored the link between postural resp...

Obesity and high myopia in children and adolescents: Korea National Health and Nutrition Examination Survey.

Mar 28, 2022

The prevalence of both obesity and myopia are increasing in Korean children and adolescents. The purpose of this study is to examine the impact of obesity on the prevalence of myopia in Korean childre...

THE QUADRANGULAR SPACE, ENDONASAL ACCESS TO MECKEL'S CAVE: TECHNICAL CONSIDERATIONS AND CLINICAL SERIES.

Mar 28, 2022

An anteromedial corridor via an expanded endoscopic endonasal approach to Meckel's Cave (MC) was described over a decade ago. However, few clinical series or endoscopic endonasal technical contributio...

Altered regional brain white matter in dry eye patients: a brain imaging study.

Mar 28, 2022

This study aimed to investigate the regional changes of brain white matter (WM) in DE patients using diffusion tensor imaging (DTI) and neurite orientation dispersion and density imaging (NODDI). A to...

Automated Diagnosis of Optical Coherence Tomography Angiography (OCTA) Based on Machine Learning Techniques.

Mar 28, 2022

Diabetic retinopathy (DR) refers to the ophthalmological complications of diabetes mellitus. It is primarily a disease of the retinal vasculature that can lead to vision loss. Optical coherence tomogr...

Non-invasive technique to detect diabetic retinopathy based on Electrooculography signal using machine learning classifiers.

Mar 28, 2022

Single-channel Electrooculogram (EOG) is proposed for detecting diabetic retinopathy. The Corneal-retinal potential of the eyes plays a vital role in the acquisition of Electrooculography. Diabetes is...

Burden and depression among informal caregivers of visually impaired patients in Mexico.

Mar 28, 2022

The needs of informal caregivers who provide care to family relatives with visual impairment are often neglected, resulting in burden and depression.To determine the degree of burden and the prevalenc...

Retinal detachment after cataract surgery: a population-based study.

Mar 28, 2022

To analyse the risk of rhegmatogenous retinal detachment (RRD) after cataract surgery, and to identify possible risk factors.Observational cohort study of patients undergoing cataract surgery in Regio...

Sex Differences in Salaries of Academic Ophthalmologists in the United States.

Mar 28, 2022

Representation of women in medicine and ophthalmology has increased in recent years. However, substantial inequities still exist between salaries for male and female physicians.To evaluate the status ...

Automated method for real-time AMD screening of fundus images dedicated for mobile devices.
