In 1958 Moses and Hahn¹ investigated the inconsistency of the low scale readings of the Schiotz tonometer noted in the report of Kronfeld² and found to cause unintelligible results in tonography.³ We found that at low scale readings (high pressures) the cornea bulges into the hole of the tonometer footplate, unduly elevating the plunger and exaggerating the estimate of intraocular pressure.

At the request of the Committee for Standardization of Tonometers, attempts have been made to quantitate this effect further.

Method

A tonometer with four interchangeable footplates was secured, the hole diameters being 3.3, 3.7, 4.0, and 4.5 mm., respectively.* All measurements were made on patients by me, with use of the technique previously described of obtaining a scale reading first with the footplate with the . . .
