BACKGROUND: Abnormal blood pressure is a potential risk factor for glaucoma. However, the role of antihypertensive medications on glaucoma pathogenesis is controversial. This study aims to investigate the association between the use of antihypertensive medications and glaucoma onset. METHODS: This nested case-control study, based on a large-scale longitudinal cohort in Australia, retrieved participants' claims records on drugs and Medicare services from national health databases. Participants with three or more claim records of anti-glaucoma medications from 2009 to 2016 were classified as glaucoma patients; those with none were classified as controls. Claim records of antihypertensive medications were identified within the 5 years before glaucoma onset and contemporary periods in matched controls without glaucoma. The association between the use of antihypertensive medications and glaucoma onset was assessed by multivariable logistic regression models. RESULTS: A total of 6748 cases and 13 496 controls were analysed. Compared with controls, the proportion of users of antihypertensive medications was slightly higher in glaucoma patients (46.9% vs. 46.0%, p > 0.05). After adjustments for demographics, health-related factors and medical history, the association between the use of antihypertensive medications and glaucoma onset was nonsignificant (OR 0.95, 95% CI = 0.89-1.02). As for specific subtypes, only beta-blocking agents (BBA) (OR 0.82, 95% CI = 0.75-0.90) and diuretics (OR 0.85, 95% CI = 0.77-0.95) were significantly associated with reduced risks of glaucoma onset. CONCLUSIONS: This study indicated that the use of antihypertensive medications was not associated with glaucoma onset. Decreased risks of glaucoma onset in users of BBA and diuretics require further validation.
