Description
We are offering three cased opthalmodyamometers ( aka tonometers) that were used for measuring ocular pressure to screen for glaucoma. On the left in the first image is a Baillart Tonometer, with a stop, in its original case, which was introduced in France in 1923. The instrument is marked “MADE IN FRANCE”. $95.00. In the center is McLeans Tonometer, first introduced in the USA in 1919; this example was made by Meyrowitz. Unlike the more widely used Schiotz,which it resembles, the McLean did not employ weights and its measurements were generally higher and less accurate. $150.00. Finally, H.K. Muller’s Opthalmodynamometer, with original paper work, made F.LK. Fischer in Freiburg. $125.00.
