Dataset of red light induced pupil constriction superimposed on post-illumination pupil response

Data in Brief, 2016
We collected and analyzed pupil diameter data from of 7 visually normal participants to compare the maximum pupil constriction (MPC) induced by “Red Only” vs.

Seasonal Variations in Adults with and without Cataracts [PDF]

, 2017
Seasonal adaptation is a ubiquitous behavior seen in many species on both global hemispheres and is conveyed by changing photoperiods. In humans this seasonal adaptation is less apparent, in part because changes in daylength are masked by the use of ...

The Preferential Impairment of Pupil Constriction Stimulated by Blue Light in Patients with Type 2 Diabetes without Autonomic Neuropathy

Journal of Diabetes Research, Volume 2017, Issue 1, 2017., 2017
The main aim of the present paper is to examine whether the pupillary light reflex (PLR) mediated by intrinsically photosensitive retinal ganglion cells (ipRGCs) is impaired in type 2 diabetic patients. One hundred and three diabetic patients without diabetic autonomic neuropathy (DAN) and 42 age‐matched controls underwent a series of detailed ...

Dominant Eye and Visual Evoked Potential of Patients with Myopic Anisometropia

BioMed Research International, Volume 2016, Issue 1, 2016., 2016
A prospective nonrandomized controlled study was conducted to explore the association between ocular dominance and degree of myopia in patients with anisometropia and to investigate the character of visual evoked potential (VEP) in high anisometropias. 1771 young myopia cases including 790 anisometropias were recruited. We found no significant relation

Decoding Color Perception: An Eye Tracking Perspective

Journal of Sensory Studies, Volume 40, Issue 2, April 2025.
ABSTRACT Eye movements scan objects and features in our environment, with color being fundamental to visual experience. Individual variations in color vision create diverse perceptual interpretations. Eye tracking provides objective quantification of these perceptual differences through fixations and gaze patterns.

Effects of mydriatics on rod/cone- and melanopsin-driven pupil responses [PDF]

, 2020
SIGNIFICANCE: Pupillometry protocols evaluating rod/cone- and melanopsin-driven responses often use mydriatics to ensure maximal stimulus exposure; however, retinal effects of mydriatics are not fully understood.

Poster Session: Chromatic and luminance contrast adaptation measured using pupillometry and SSVEP

Journal of Vision
Previous evidence suggests both chromatic and luminance contrast adaptation reduces contrast sensitivity in the post-adaptation period. This effect is chromatically-tuned: adaptation is greatest when the adaptor and probe lie on the same chromatic axis. Previous fMRI data from our lab also suggests S-cone adaptation results in a paradoxical increase in

Chromatic Pupillometry Dissects Function of the Three Different Light-Sensitive Retinal Cell Populations in RPE65 Deficiency

Investigative Opthalmology & Visual Science, 2012
The aim of the study was to objectively characterize the function of rods, cones, and intrinsic photosensitive retinal ganglion cells (ipRGCs) in patients with RPE65 mutations by using two published protocols for chromatic pupillometry, and to correlate the data with the clinical phenotype.The study group comprised 11 patients with RPE65 mutations, and
