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 showing the development of open angle glaucoma after accounting for censoring due to death or end of observation. There was a significantly higher cumulative incidence of open angle glaucoma development in patients with migraine than in non-migrainous controls. (P = .0217, log-rank test)
