Visual snow manifests as a pan-field, dynamic visual disturbance described as continuous TV-static-like tiny flickering dots. Current diagnostic criteria further require at least two additional symptoms for the Visual Snow Syndrome (VSS) from: palinopsia (afterimages and trailing), entoptic phenomena (floaters, blue field entoptic phenomenon, photopsia, self-light of the eye), photophobia and nyctalopia. Our objective was to compare the phenotype of VSS in an Italian and British population.
