Summary

Authors have performed intraocular tension measurements on 288 eyes in adults with the Mackay-Marg and Goldmann applanation tonometers in a sitting position with prior topical anaesthesia. The series of measurements exhibiting tonograms with expressed posterior crest gave readings much higher than those obtained with the Goldmann tonometer. Statistical evaluation of the self-reproducibility of observer was carried out as well as the investigation of the number of tonograms needed for obtaining the most valid value of the basal intraocular pressure and of the influence of the order of succession of the measurements with different instruments by means of the Williams square, respectively.

Zusammenfassung

Die Verfasser haben den intraocularen Druck an 288 Augen Erwachsener mit den Mackay-Margschen und Goldmannschen Applanationstonometern im Sitzen nach vorangehender örtlicher Betäubung gemessen. Die Meßreihen, die Tonogramme mit ausgesprochenem hinteren Kurvenanstieg aufwiesen, ergaben viel höhere Druckwerte als die Meßresultate mit dem Goldmannschen Tonometer. Die statistischen Auswertungen erstreben Aussagen zur Eigenreproduzierbarkeit, die zum schlüssigen basalen Augendruck nötige Zahl der Tonogramme und den Effekt der Reihenfolge der Messungen mit verschiedenen Instrumenten auf den Druckwert mittels des Williams-Quadrats.
