Abstract
Purpose :
Prior observational studies have demonstrated an increased risk of primary open-angle glaucoma (POAG) associated with systemic use of calcium channel blockers (CCBs), but several were limited by lack of diversity in the cohorts studied. We aimed to evaluate the association between CCBs and POAG incidence using a diverse, nationwide dataset.
Methods :
We conducted a retrospective analysis of 213,424 individuals aged 40 years and older in the National Institutes of Health (NIH) All of Us dataset1, notable for its demographic, geographic, and medical diversity, and inclusion of historically underrepresented populations. Patients diagnosed with POAG before any anti-hypertensive medication use were excluded. Bivariate and multivariable regression analyses were performed using R.
Results :
Within our cohort, 2772 participants (1.3%) were diagnosed with POAG based on electronic health record (EHR) data, while 210,652 (98.7%) did not. Among patients with POAG, the mean age was 73.3 years, 52.5% were female, and 48.2% identified as White. Among POAG patients, 32.6% used any CCB, 28.2% used a dihydropyridine CCB, and 2.2% used a non-dihydropyridine CCB. In bivariate analysis, use of any CCBs was associated with an increased risk of POAG (OR: 1.29, 95% CI: 1.27-1.31, p<0.001). In multivariable analysis adjusting for age, gender, race/ethnicity, comorbidities, and use of other anti-hypertensive medications, use of CCBs remained associated with an increased risk of developing POAG (OR: 1.55, 95% CI: 1.36-1.77, p<0.001). When stratified by type of CCB, the use of dihydropyridine CCBs (OR: 1.34, 95% CI: 1.17-1.54, p<0.001) was associated with increased POAG risk (Table 1).CCB use was associated with a significantly higher risk of POAG2, even after adjusting for demographic factors, comorbid medical conditions, and use of other antihypertensive medications. When stratified by type of CCB, the use of dihydropyridine CCBs remained associated with an increased incidence of POAG in multivariable analysis.
Conclusions :
These findings emphasize the potential impact of systemic antihypertensive medications on POAG incidence.3 Reducing use of CCBs may be another target for therapeutic intervention in patients with POAG among those who have concomitant hypertension.
