Rare Co-Occurrence of Visual Snow in a Female Carrier With RPGRORF15-Associated Retinal Disorder

Frontiers in Genetics, 2021
X-linked retinitis pigmentosa (XLRP), a rare form of retinitis pigmentosa (RP), is predominantly caused by mutations in the retinitis pigmentosa GTPase regulator (RPGR) gene. Affected males often present with severe phenotypes and early disease onset. In

Delayed Onset of Inhibition of Return in Visual Snow Syndrome

Frontiers in Neurology, 2021
Visual snow syndrome (VSS) is a complex, sensory processing disorder. We have previously shown that visual processing changes manifest in significantly faster eye movements toward a suddenly appearing visual stimulus and difficulty inhibiting an eye ...

Widespread White Matter Alterations in Patients With Visual Snow Syndrome

Frontiers in Neurology, 2021
Background: Visual snow is considered a disorder of central visual processing resulting in a perturbed perception of constant binocular flickering or pixilation of the whole visual field.

Visual snow syndrome and migraine: a review

Eye, 2023
AbstractVisual snow syndrome is a neurological condition characterized by ongoing prominent phenomena described consistently as tiny dots moving across the entire visual field, often associated with complex visual symptoms. These can take the form of afterimages, entoptic phenomena, nyctalopia and light sensitivity.

Visual Snow Syndrome

Journal of the Foundations of Ophthalmology
Visual Snow Syndrome (VSS) is a neurological disorder of visual perception characterised by continuous, flickering dots resembling the noise of a detuned television, affecting the entire visual field. This “visual static” or “visual snow” is continuous, may be black-and-white or coloured, and can appear flashing or transparent.

Adhesion of Wet Snow to Different Cable Surfaces [PDF]

Cohesion of snow and its adhesion to cable surfaces are the decisive factors for wet-snow shedding from power-line cables. Knowing the adhesive strength of snow is essential to predict when snow will shed and what consequences it will have on the ...

Neuroimaging in Visual Snow - A Review of the Literature

Frontiers in Ophthalmology, 2022
Since the first description of visual snow syndrome (VSS) in 1995, there has been increasing interest particularly within the past 5-10 years in phenotyping the condition and differentiating it from conditions such as migraine with aura and hallucinogen persisting perception disorder.

Modeling Wet-Snow Shedding from Current-Carrying Conductors [PDF]

The initiation of wet-snow shedding from currentcarrying conductors was studied experimentally and theoretically. A suspended cable with cylindrical snow accretion was considered, and some of the snow properties at the end of sleeve were measured and ...

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.

Abnormal Connectivity and Brain Structure in Patients With Visual Snow

Frontiers in Human Neuroscience, 2020
ObjectiveVisual snow (VS) is a distressing, life-impacting condition with persistent visual phenomena. VS patients show cerebral hypermetabolism within the visual cortex, resulting in altered neuronal excitability.
