Presence and severity of migraine is associated with development of primary open angle glaucoma: A population-based longitudinal cohort study
Abstract
Purpose To examine the association between the presence and severity of migraine and development of primary open-angle glaucoma (POAG) using a nationwide population-based longitudinal cohort data. Methods Data were retrieved from the Korean National Health Insurance Service for 2,716,562 individuals aged ≥ 40 years and assessed for the development of POAG from 2009 through 2018. Subjects were classified into the following 3 groups: healthy control subjects, subjects with mild migraine, and those with severe migraine. Hazard ratios (HR) of glaucoma development were calculated for each group. Subgroup analyses of subjects stratified by age, sex, lifestyle factors (smoking, drinking, and body mass index (BMI)), and comorbidities (diabetes, hypertension, and dyslipidemia). Results During the 9-year follow-up period, the incidence rate of POAG per 1000 person-years was 2.41 and 3.25 in subjects without and with migraine, respectively. Among the migraine group, the incidence rate was 3.14 and 3.89 in mild and severe subgroups, respectively. The HR was 1.355 (95% CI, 1.300–1.412) and 1.188 (95% CI, 1.140–1.239) before and after adjusting for potential confounding factors in the migraine group per se. Regarding the severity of migraine, the adjusted HRs were 1.169 (95% CI, 1.117–1.224) in the mild migraine group, and 1.285 (95% CI, 1.166–1.415) in the severe migraine group compared to the control group. The results were consistent in subgroup analyses after stratifying by age, sex,…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 2,716,562 participants or records.
