Summary
Intraocular pressure was measured with Goldmann applanation tonometers by two independent examiners in 420 eyes. A difference between measurements of at least 3 mm Hg occurred in 30% of the eyes. Some evidence suggests that the differences between pressure measurements were caused by actual changes of intraocular pressure rather than by instrument inaccuracy or technician error.
Zusammenfassung
Der Innendruck von 420 Augen wurde mit dem Goldmann-Tonometer von zwei Untersuchern unabhängig voneinander gemessen. Ein Unterschied von 3 oder mehr mm Hg wurde bei 30% der Augen gefunden. Verschiedene Ergebnisse lassen vermuten, daß die Unterschiede in den Druckmessungen durch eine tatsächliche Änderung des Augeninnendruckes verursacht werden und weder durch Ungenauigkeit des Instrumentes noch durch Fehler der Untersucher.
