Notes that visual snow syndrome is characterized by continuous, tiny dots across the entire visual field representing TV static.

Valeria Albano, S. Guerriero, G. Alessio. Visual snow: a neuro-ophthalmic syndrome. 2022. https://doi.org/10.51329/mehdioptometry132

Defines visual snow syndrome as a neuro-ophthalmic disorder manifesting as the perception of tiny, simultaneous dots throughout the visual field resembling TV static.
