dc.descriptionTwenty-three patients recruited from an online community for people with VSS were included in the study. All patients were examined by a neurologist who collected information about their neurologic and visual symptoms. In 12 subjects the VS was present from an early age (~ <10 years). In 11 subjects, it appeared after the age of 14 years. Six of these 11 participants attributed the onset of VS to stress. Subjects who acquired VS as a result of substance abuse were excluded from the study. All but two VSS participants were medication-free. Two participants were taking antidepressants in low doses (venlafaxin, 75 mg per day, or escitalopram, 5 mg per day, both longer than 3 months). We also recruited 27 sex- and age-matched neurologically healthy control participants from the community. The characteristics of the subjects are presented in Table 1. All subjects were asked to complete the Russian version of the Visual Discomfort Scale (Conlon, Lovegrove, Chekaluk, & Pattison, 1999), which assesses unpleasant somatic and perceptual side effects of viewing patterns. Participants were also asked to complete the Russian version State-Trait Anxiety Inventory (Spielberger, 1983).
dc.description.abstractUsing a spatial suppression paradigm, we assessed motion duration discrimination thresholds for small (1°), medium (2.5°), and large (12°) high-contrast gratings in 23 VSS and 27 control participants. Spatial Suppression Index (SSI) quantified size-dependent increases in duration thresholds. Visual Discomfort Questionnaire scores and VSS symptom ratings including TTP, afterimages, photophobia, etc. were also collected. VSS patients reported higher visual discomfort and perceptual disturbances. However, no group differences were found in duration thresholds or SSI. Notably, higher TTP scores were associated with lower duration thresholds, indicating a facilitatory effect of TTP on motion sensitivity.
