Visual Field Coordinate Systems in Visual Neurophysiology [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2023
In this work, algorithms have been developed to: 1. Compare visual field coordinate data, presented in different representation systems; 2. Determine the distance in degrees between any two points in the visual field; 3.

Opposite response of blood vessels in the retina to 6° head-down tilt and long-duration microgravity

open access: yesnpj Microgravity, 2021
The Spaceflight Associated Neuro-ocular Syndrome (SANS), associated with the headward fluid shifts incurred in microgravity during long-duration missions, remains a high-priority health and performance risk for human space exploration.

Reliability of Visual Field Index in Staging Glaucomatous Visual Field Damage [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2018
Introduction: Standard automated perimetry is integral to the testing of visual function in glaucoma. Classification of glaucomatous visual field defects into different severity levels is important to guide effective management; but the available ...

Slowed Saccadic Reaction Times in Seemingly Normal Parts of Glaucomatous Visual Fields

open access: yesFrontiers in Medicine, 2021
Purpose: In eye movement perimetry, peripheral stimuli are confirmed by goal-directed eye movements toward the stimulus. The saccadic reaction time (SRT) is regarded as an index of visual field responsiveness, whereas in standard automated perimetry (SAP)

Diversity and evolution of optically complex eyes in a family of deep-sea fish: Ocular diverticula in barreleye spookfish (Opisthoproctidae)

open access: yesFrontiers in Ecology and Evolution, 2022
Several families of mesopelagic fish have tubular eyes that are usually upwardly directed. These maximise sensitivity to dim downwelling sunlight and dorsal bioluminescence, as well as facilitating the detection of dark silhouettes above the animal. Such

Spectacles with highly aspherical lenslets for myopia control do not change visual sensitivity in automated static perimetry

open access: yesFrontiers in Neuroscience, 2022
PurposeSpectacle lenses with arrays of lenslets have gained popularity in myopia control due to their high efficacy, low impact on visual performance, and non-invasiveness.

The application of artificial intelligence in glaucoma diagnosis and prediction

open access: yesFrontiers in Cell and Developmental Biology, 2023
Artificial intelligence is a multidisciplinary and collaborative science, the ability of deep learning for image feature extraction and processing gives it a unique advantage in dealing with problems in ophthalmology.
