Original art paintings are chosen over their "color-rotated" versions because of changed color contrast. [PDF]

Perception
Rotating colors (digitally within CIELAB color space) of an artistic painting is thought to keep constant all aspects of the painting except the hues.

Development of an Innovative Pupillometer Able to Selectively Stimulate the Eye's Fundus Photoreceptor Cells. [PDF]

Diagnostics (Basel)
Recent advancements in clinical research have identified the need to combine pupillometry with a selective stimulation of the eye's photoreceptor cell types to broaden retinal and neuroretinal health assessment opportunities. Our thorough analysis of the

Handheld chromatic pupillometry can accurately and rapidly reveal functional loss in glaucoma. [PDF]

Br J Ophthalmol, 2023
Background/aimsEarly detection and treatment of glaucoma can delay vision loss. In this study, we evaluate the performance of handheld chromatic pupillometry (HCP) for the objective and rapid detection of functional loss in glaucoma.MethodsIn this clinic-based, prospective study, we enrolled 149 patients (median (IQR) years: 68.5 (13.6) years) with ...

Effects of low and moderate refractive errors on chromatic pupillometry. [PDF]

Sci Rep, 2019
AbstractChromatic pupillometry is an emerging modality in the assessment of retinal and optic nerve disorders. Herein, we evaluate the effect of low and moderate refractive errors on pupillary responses to blue- and red-light stimuli in a healthy older population.

Abnormal pupillary light reflex with chromatic pupillometry in Gaucher disease. [PDF]

Ann Clin Transl Neurol, 2014
The hallmark of neuronopathic Gaucher disease (GD) is oculomotor abnormalities, but ophthalmological assessment is difficult in uncooperative patients. Chromatic pupillometry is a quantitative method to assess the pupillary light reflex (PLR) with minimal patient cooperation.

Ocular changes as potential biomarkers for early diagnosis of Alzheimer's disease. [PDF]

Alzheimers Dement
Abstract Alzheimer's disease (AD) is a progressive neurodegenerative disorder and the most common cause of dementia. AD diagnosis often involves a thorough assessment, including clinical evaluation, cognitive testing, medical history examination, genetic testing, and biomarker analysis. Currently, the invasive nature and high costs of biomarker testing,

Colour perception changes with basic colour word comprehension

Developmental Science, Volume 26, Issue 6, November 2023., 2023
Abstract Recent work has investigated the origin of infant colour categories, showing pre‐linguistic infants categorise colour even in the absence of colour words. These infant categories are similar but not identical to adult categories, giving rise to an important question about how infant colour perception changes with the learning of colour words ...

Eye blinking, musical processing, and subjective states—A methods account

Psychophysiology, Volume 60, Issue 10, October 2023., 2023
Abstract Affective sciences often make use of self‐reports to assess subjective states. Seeking a more implicit measure for states and emotions, our study explored spontaneous eye blinking during music listening. However, blinking is understudied in the context of research on subjective states.

Pupillary Responses to High-Irradiance Blue Light Correlate with Glaucoma Severity [PDF]

, 2014
PurposeTo evaluate whether a chromatic pupillometry test can be used to detect impaired function of intrinsically photosensitive retinal ganglion cells (ipRGCs) in patients with primary open-angle glaucoma (POAG) and to determine if pupillary responses ...

Clinical Outcomes with Extended Depth of Focus Intraocular Lenses in Cases in Which Multifocal Lenses Are Not Primarily Recommended

Journal of Ophthalmology, Volume 2023, Issue 1, 2023., 2023
Purpose. The purpose of the study is to evaluate the visual and patient‐reported outcomes of patients undergoing cataract surgery with implantation of an extended depth of focus (EDOF) intraocular lens (IOL) who were not primarily good candidates for multifocal IOL implantation. Methods.
