A flowchart of study population selection. From 1,137,861 subjects, those with previous glaucoma diagnosis (n = 15,992), previous glaucoma medication use (n = 8,514), previous HTN diagnosis (n = 35,952) and previous antihypertensive medication use (n = 98,522) were excluded. Subjects with HTN diagnosis were identified, and those with subsequent diagnosis of OAG were matched to 5 controls to obtain a final sample of 31,170 subjects for analysis.
