title: [The Mackay-Marg-tonometer. A clinically applicable measuring apparatus for Pt-values (author's transl)].
abstract: Comparative pressure measurements on the corneae of enucleated eyes and on a 0.05 mm-thick rubber membrane showed that the Pt-values obtained by the MMT can be sufficiently exactly controlled. An air chamber attached to a Hg-manometer has in an upper wall a round window 8 mm in diameter, closed by a 0.05 mm-thick rubber membrane. The sensor of the MMT is mechanically fixed over the window so that the foot plate of the sensor indents the rubber membrane by 1 mm. The pressure in the chamber can be varied at will by vanying the amount of air in it.
