[Current state of ophthalmic tonometry]

Currently, the level of intraocular pressure (IOP) can be assessed with a large number of tonometers, which differ in the principle of action, the place of application and the degree of invasiveness. All the methods in use - except for direct manometry - allow only indirect judgement of the level of ophthalmotonus. The quality of tonometric measurement is influenced by many factors, from the choice of tonometer to the analysis of the results obtained by the doctor. The use of complex methods for assessing the level of intraocular pressure provides additional information that increases its diagnostic value. This article summarizes current information about modern methods of tonometry, and describes their features.
