A member asked:
Why does the air puff tonometer give me wildly different readings? i had it taken5x in a row. # was anywhere between16-27. which numbers are accurate?
A doctor has provided 1 answer
Average: You're supposed to average 3 readings on an air puff tonometer (for each eye) to get "the number" for that day. Goldman tonometers are supposed to be more accurate than air puff tonometers (http://www.ncbi.nlm.nih.gov/pubmed/1822985). Also, the tonometer reading changes from moment to moment depending on your (arm) blood pressure, mood, activity, etc. See www.fiteyes.com/The-Air-Puff-Tonometer
