In the therapeutic management of glaucoma, the clinician must determine a target intraocular pressure (IOP). Goldmann applanation tonometry is the standard of care for measuring IOP. This study investigates the calibration accuracy of the Goldmann tonometers in Pacific University's primary care and ocular disease clinics to see if variations when using different Goldmann tonometers on successive visits could significantly affect the outcome of IOP measurement. Our results showed that the Goldamnn tonometers at Pacific University's optometry clinics are sufficiently calibrated and will have an insignifcant effect on the determination of achievement of target IOP when therapeutically managing glaucoma.
