title: [The Stepanik arteriotonograph (author's transl)].
abstract: A pressure-sensitive probe, specially developed for this purpose, is built into a contact lens in such a manner that when adjusted to the patient's eye the probe registers the intraocular pressure whilst the observer compresses the eyeball and observes the arterial collapse phenomenon on the disc over the contact lens on the slit-lamp microscope. The standard deviation of a clinical measurement is 1.5 mm Hg. Derived from measurements on 65 eyes of patients without signs of vascular disorder, the correlation of the systolic and diastolic ophthalmic artery-pressure (y) to that of the ipsilateral brachial artery (x) is given by Y =0.79x-1.33 (r=0.96) and the correlation of their median pressure by Y=0.93x-17.2 (r=0.94).
