Systemic beta blockers have ‘negligible’ effect on IOP reduction

Non-glaucoma subjects who take selective or non-selective systemic beta blockers did not experience significantly lowered IOP, according to a study. Researchers evaluated the IOP of 13,527 non-glaucoma subjects in the Gutenberg Health Study, a population-based, prospective, observational cohort study in Germany. Several cardiovascular medications, including beta blockers, calcium channel blockers, renin-angiotensin blockers and other medications, were evaluated, and IOP was measured with a non-contact tonometer.
