Purpose: Multifocal pupillographic objective perimetry (mfPOP) is being developed as an
alternative to subjective threshold perimetry for the management of visual and neurological …

Background: The pupillary light reflex is weaker for stimuli presented inside as compared to
outside absolute scotomas. Pupillograph perimetry could thus be an objective measure of …

Background To establish the effects of stimulating intrinsically-photosensitive retinal
ganglion cells (ipRGCs) on migraine severity, and to determine if migraine produces …

Purpose: To assess alterations in quantitative dynamic pupil responses to light in relation to
neurologic disability and retinal axonal loss in patients with multiple sclerosis (MS) …

Purpose To investigate safety and visual-field changes in people with epilepsy undergoing
multifocal Pupillographic Objective Perimetry (mfPOP). Methods 15 people with epilepsy …

Equiluminant stimuli help assess the integrity of colour perception and the relationship of
colour to other visual features. As a result of individual variation, it is necessary to calibrate …

The assessment of the visual field in young children continues to be a challenge. Children
often do not sit still, fail to fixate stimuli for longer durations, and have limited verbal capacity …

The optic quality of the eyes is, at least in part, determined by pupil size. Large pupils let
more light enter the eyes, but degrade the point spread function, and thus the spatial …

To this day, the most popular method of choice for testing visual field defects (VFDs) is
subjective standard automated perimetry. However, a need has arisen for an objective, and …

Purpose: A scene consisting of a white stimulus on a black background incorporates strong
luminance contrast. When both stimulus and background receive different colors, luminance …
