content: An optical tonometer determines intraocular pressure by measuring the resistance of a cornea to indentation. The basic form was invented by a German professor in 1862. The “Professor Schioetz’s / Tonometer” inscription on the case of this example refer to Hjalmar August Schiőtz, a Norwegian ophthalmologist who presented his design to the Norwegian Medical Society in 1905. Those on the front of the instrument read “ADAMS” and “GERMANY” and “3662”. Those on the back read “D.R.G.M.” and “26.”
