Unilateral anterior ischemic optic neuropathy: chromatic pupillometry in affected, fellow non-affected and healthy control eyes [PDF]

Frontiers in Neurology, 2013
The intrinsically photosensitive retinal ganglion cells (ipRGCs) express the photopigment melanopsin, which is sensitive to blue light. Previous chromatic pupillometry studies have shown that the post-illumination response is considered an indicator of ...

Chromatic Pupillometry in Isolated Rapid Eye Movement Sleep Behavior Disorder [PDF]

Movement Disorders, 2022
AbstractBackgroundMelanopsin retinal ganglion cell (mRGC)‐mediated pupillary light reflex (PLR) abnormalities have been documented in several neurodegenerative disorders including Parkinson's disease. Overall, isolated rapid eye movement (REM) sleep behavior disorder (iRBD) represents the strongest prodromal risk factor for impending α ...

Abnormal pupillary light reflex with chromatic pupillometry in G aucher disease [PDF]

Annals of Clinical and Translational Neurology, 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.

The diagnostic significance of pupillary reflex pathways: insights from classical examination and advanced pupillometry [PDF]

Frontiers in Neuroscience
Background/objectivesThe pupil, a dynamic ocular structure, serves as a critical indicator of neurological and ophthalmological function. This interdisciplinary review explores the anatomical, physiological, and pathological aspects of pupillary reflexes

Chromatic Pupillometry as a Putative Screening Tool for Heritable Retinal Disease in Rhesus Macaques. [PDF]

Transl Vis Sci Technol, 2023
Non-human primates (NHPs) are useful models for human retinal disease. Chromatic pupillometry has been proposed as a noninvasive method of identifying inherited retinal diseases (IRDs) in humans; however, standard protocols employ time-consuming dark adaptation.

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.

Automatic Detection of Genetic Diseases in Pediatric Age Using Pupillometry

IEEE Access, 2020
Inherited retinal diseases cause severe visual deficits in children. They are classified in outer and inner retina diseases, and often cause blindness in childhood.
