From: Migraine and increased risk of developing open angle glaucoma: a population-based cohort study
Kaplan–Meier curve of patients with migraine and of non-migrainous controls with an age-adjusted Charlson comorbidity score ≥ 1 for the development of open angle glaucoma. The cumulative incidence rate of open angle glaucoma development in patients with migraine was not significantly different from that in non-migrainous controls (P = .7592, log-rank test)
