[The Mackay-Marg-tonometer. VII. The continuous registration of the intraocular pressure (author's transl)].

The Mackay-Marg-Tonometer registers continuously the intraocular pressure (Pt) as exactly as an electromanometer connected with the eye provided that the corneal rigidity is eliminitated by a smooth indentation of the cornea by the tip of the probe, the determined deviation of the registered values from linearity is considered and the temperature of the probe is not influenced from outside.
