Melanopsin-mediated pupillary responses in bipolar disorder—a cross-sectional pupillometric investigation

International Journal of Bipolar Disorders, 2021
Background Visible light, predominantly in the blue range, affects mood and circadian rhythm partly by activation of the melanopsin-containing intrinsically photosensitive retinal ganglion cells (ipRGCs).

The History of Pupillography and Possibility of Its Using in Modern Ophthalmology

Oftalʹmologiâ, 2022
Nowadays medicine has great opportunities for a detailed study of organs and systems, quick and accurate diagnosis of norm or pathology. Many diagnostic procedures are universal and are used by doctors of different specialties.

Evaluating State-of-the-Art Computerized Pupillary Assessments for Glaucoma Detection: A Systematic Review and Meta-Analysis

Frontiers in Neurology, 2020
Computerized pupillary light reflex assessment devices (CPLRADs) may serve as an effective screening tool for glaucomatous optic neuropathy, since they can dynamically detect abnormal pupillary responses from a novel sequence of light stimuli and ...

Melanopsin Retinal Ganglion Cells and Pupil: Clinical Implications for Neuro-Ophthalmology

Frontiers in Neurology, 2018
Melanopsin retinal ganglion cells (mRGCs) are intrinsically photosensitive RGCs that mediate many relevant non-image forming functions of the eye, including the pupillary light reflex, through the projections to the olivary pretectal nucleus.

Pupillometry evaluation of melanopsin retinal ganglion cell function and sleep-wake activity in pre-symptomatic Alzheimer's disease.

PLoS ONE, 2019
BackgroundMelanopsin-expressing retinal ganglion cells (mRGCs), intrinsically photosensitive RGCs, mediate the light-based pupil response and the light entrainment of the body's circadian rhythms through their connection to the pretectal nucleus and ...

Light-Induced Pupillary Responses in Alzheimer's Disease

Frontiers in Neurology, 2019
The impact of Alzheimer's disease (AD) on the pupillary light response (PLR) is controversial, being dependent on the stage of the disease and on the experimental pupillometric protocols.

Melanopsin Cell Dysfunction is Involved in Sleep Disruption in Parkinson’s Disease

Journal of Parkinson’s Disease, 2020
Background: Melanopsin-expressing intrinsically photosensitive retinal ganglion cells (ipRGCs) signal the environmental light to mediate circadian photoentrainment and sleep-wake cycles.
