Question:
Since measuring intraocular pressure is so pivotal in the diagnosis and treatment of glaucoma, how is tonometry equipment calibrated (checked for accuracy) and how often is this carried out?

With a Goldmann Applanation Tonometer, there is a calibration weight bar that comes with every device. The manufacturer recommends a monthly calibration.
