Figure 3. — Individual L-VISS scores and mean per subgroup demonstrate effect of aura and chronic migraine on visual sensitivity. Participants with migraine reported interictal (light gray) and ictal (dark gray) scores. Subgroup scores are presented as mean and SD. Healthy controls (mean L-VISS score 3.6), and participants with episodic migraine without (interictal: 8.5/ictal: 18.3) and with aura (11.3/21.2) and participants with chronic migraine without (10.9/23.0) and with aura (17.8/25.8) were compared in-between and during attacks. Diagnosis, aura status, and attack status all affected the outcome (P < 0.001 per factor). L-VISS, Leiden Visual Sensitivity Scale.
