There are very few instances in which a patient with chronic glaucoma needs monthly IOP checks (vs someone who came into clinic with an acute event and goes on to need emergent surgery.) And in those cases where monthly IOP checks are needed, it is definitely not gold standard to use the air puff test.
I'd say that measuring IOP every 3-4 months is a typical regimen for a patient with more advanced glaucoma; these measurements should always be done via the same method (Goldman applanation) at the same time of day (due to AM to PM fluctuations in IOP) to be the most accurate.
