Abstract

The correct interpretation of measured tonometric values has become more and more complex in recent years. Large clinical studies have shown that an average central corneal thickness (CCT) of 550 µm can be assumed for the general population. Since the standard Glodmann applanation tonometry is based on a central corneal thickness of 520 µm, mathematical correction formula have been discussed for calculation of the true intraocular pressure. Newer tonometry devices, e. g. the dynamic contour tonometry (DCT) which seems to be independent from CCT, or the Ocular Response Analyzer® (ORA), taking into account the biomechanical properties of the cornea, have been designed to measure intraocular pressure (IOP). In this article, several IOP measurement devices and their clinical relevance for a correct and feasible determination of the IOP are discussed.
