[Principle and results of a new "non-contact-tonometer" are discussed (author's transl)].
Comparing measurements with Non-Contact-Tonometer and handapplanation tonometer on 462 eyes with normal and elevated intraocular tension are statistically evaluated. The 2-s-limits for normal i.o. pressure at +/- 6.52 mm Hg (+/- 8.6 mbar), for elevated intraocular pressure +/- 13.2 mm Hg (+/- 17.6 mbar). This means less reliability than conventional applanation tonometers or even Schiötz-tonometers. The unability to read the tension when the corneal surface is rough means remarkable disadvantages to clinical use.
