Visual snow: a neuro-ophthalmic syndrome

Medical hypothesis, discovery & innovation in optometry, 2022
Background: The visual snow syndrome (VSS) is a rare disease characterized by persistent positive visual phenomena that are enigmatic and may be underestimated. It manifests as the perception of tiny, simultaneous, diffuse, and mobile dots frequently throughout the visual field.

Abnormal Glutamatergic and Serotonergic Connectivity in Visual Snow Syndrome and Migraine with Aura

Annals of Neurology, 2023
Neuropharmacological changes in visual snow syndrome (VSS) are poorly understood. We aimed to use receptor target maps combined with resting functional magnetic resonance imaging (fMRI) data to identify which neurotransmitters might modulate brain ...

The frequency of the 'visual snow' phenomenon in patients with migraine [PDF]

Medicinski Podmladak, 2017
Introduction: 'Visual Snow' phenomenon represents visual disturbances, which consist of small, dynamic, flickering dots present in both eyes, in the entire visual field, like the interference of static electricity, so-called 'snow' on the old, analog TVs.

Visual snow syndrome: what we know so far.

, 2018
PURPOSE OF REVIEW We provide an overview of the neurological condition known as visual snow syndrome. Patients affected by this chronic disorder suffer with a pan-field visual disturbance described as tiny flickering dots, which resemble the static ...

Brain network dynamics in people with visual snow syndrome

Human Brain Mapping, 2022
AbstractVisual snow syndrome (VSS) is a neurological disorder characterized by a range of continuous visual disturbances. Little is known about the functional pathological mechanisms underlying VSS and their effect on brain network topology, studied using high‐resolution resting‐state (RS) 7 T MRI.

Altered functional connectivity strength between structurally and functionally affected brain regions in visual snow syndrome

Brain Communications
Visual snow syndrome (VSS) is a neurological disorder that is predominantly characterized by persistent, dynamic visual disturbances, experienced across the entire visual field.

National and International Monitoring of Student Literacy and Numeracy Attainment: The Case for Rigorous Macro and Micro Analysis

Australian Journal of Social Issues, EarlyView.
ABSTRACT In her 2024 paper Are Australian students' academic skills declining? Interrogating 25 years of national and international standardised assessment data, Larsen compiled an impressive summary of major international (PISA, PIRLS and TIMSS) and national (NAPLAN) standardised assessments pertaining to literacy and numeracy.

Characteristics of visual snow syndrome in Japan and its association with migraine

Cephalalgia
Objective Visual snow syndrome (VSS) is closely linked to migraine and involves variable visual disturbances. The present study aimed to investigate the associations between VSS and migraine, as well as VSS and anisometropia.

Visual Snow Syndrome Improves With Modulation of Resting-State Functional MRI Connectivity After Mindfulness-Based Cognitive Therapy: An Open-Label Feasibility Study

Journal of neuro-ophthalmology, 2023
Supplemental Digital Content is Available in the Text. Background: Visual snow syndrome (VSS) is associated with functional connectivity (FC) dysregulation of visual networks (VNs). We hypothesized that mindfulness-based cognitive therapy, customized for

Tachinidae (Diptera) as Floral Visitors and Pollinators in Natural and Managed Systems

Entomologia Experimentalis et Applicata, EarlyView.
We review the roles of bristle flies (Tachinidae) as pollinators in natural and managed systems. We find that most tachinid genera visit flowers and that floral‐adapted mouthparts have evolved repeatedly many times in the family. We review patterns of floral specificity and assess the efficacy of tachinids as pollinators with case studies.
