BP measurements were available for 475,166 participants. During the baseline assessment center visit, two automated readings were taken a few moments apart using an OMRON 705 IT electronic BP monitor (OMRON Healthcare Europe, Hoofddorp, Netherlands). An average value of the two readings was calculated and then adjusted for BP-lowering medication by adding 15 mm Hg, as described previously.17 (link) This antihypertensive medication–adjusted phenotype was used in all analyses. SBP, diastolic blood pressure (DBP), and pulse pressure (PP) were analyzed independently in order to understand the impact of different aspects of BP on IOP or glaucoma.
