Reconsidering the Gold Standard of Tonometry

Απόσπασμα:

"THE CURRENT GOLD STANDARD

Imagine a tonometer that is heavily influenced by the operator, so much so that a masked reader is required when IOP is a main outcome measure in a study. One person physically applies the tonometer, while another reads the result. This same tonometer is also markedly influenced by corneal thickness and many other factors- known and unknown. Of course, I am referring to the Goldmann tonometer, which has been and often still is considered the gold standard of tonometry, yet this instrument's inaccuracy and imprecision are well documented. Why is it still considered a gold standard?"
