LIGHT ADAPTATION AT THE FOVEA FOR NORMAL EYES [PDF]

open access: yesBritish Journal of Ophthalmology, 1939
As a result of experiments on the foveal adaptation process by the method of binocular matching' 2 it seemed likely that data obtained from observers with defective vision might lead to further knowledge of the retinal processes and of certain diseases of the eye and might in some cases assist in their diagnosis. Before this possibility could be tested,

Impact of walking speed and motion adaptation on optokinetic nystagmus-like head movements in the blowfly Calliphora

open access: yesScientific Reports, 2022
The optokinetic nystagmus is a gaze-stabilizing mechanism reducing motion blur by rapid eye rotations against the direction of visual motion, followed by slower syndirectional eye movements minimizing retinal slip speed.

Adaptation to size affects saccades with long but not short latencies [PDF]

open access: yes, 2016
Maintained exposure to a specific stimulus property-such as size, color, or motion-induces perceptual adaptation aftereffects, usually in the opposite direction to that of the adaptor. Here we studied how adaptation to size affects perceived position and

Visual recovery from optic atrophy following acute optic neuropathy in the fellow eye

open access: yesJournal of Research in Medical Sciences, 2012
The left eye of a 65-year-old male was blind due to optic atrophy and only seeing eye had also dry type age-related macular degeneration. An anterior ischemic optic neuropathy developed in the better seeing eye.

Deficient vergence prism adaptation in subjects with decompensated heterophoria.

open access: yesPLoS ONE, 2019
Vergence prism adaptability was evaluated in subjects with high symptomatic and asymptomatic heterophoria and compared to individuals with a heterophoria within normal range (the control group). A computer haploscope was used to measure phoria values and

Turning the tide of corneal blindness

open access: yesIndian Journal of Ophthalmology, 2012
Corneal diseases represent the second leading cause of blindness in most developing world countries. Worldwide, major investments in public health infrastructure and primary eye care services have built a strong foundation for preventing future corneal ...

A chromosome-level genome of Astyanax mexicanus surface fish for comparing population-specific genetic differences contributing to trait evolution

open access: yesNature Communications, 2021
Mexican Tetra cavefish have long been of interest in understanding adaptation to severe environmental change. Here the authors present a chromosome-level genome for the proxy-ancestral surface fish, and use CRISPR gene-editing to show the role of the rx3

The Neuroergonomics of Aircraft Cockpits: The Four Stages of Eye-Tracking Integration to Enhance Flight Safety

open access: yesSafety, 2018
Commercial aviation is currently one of the safest modes of transportation; however, human error is still one major contributing cause of aeronautical accidents and incidents.

Abnormal Fixational Eye Movements in Amblyopia. [PDF]

open access: yesPLoS ONE, 2016
PURPOSE:Fixational saccades shift the foveal image to counteract visual fading related to neural adaptation. Drifts are slow eye movements between two adjacent fixational saccades.

Human visual response to nuclear particle exposures [PDF]

open access: yes, 1972
Experiments with accelerated helium ions were performed in an effort to localize the site of initial radiation interactions in the eye that lead to light flash observations by astronauts during spaceflight.
