The World Health Organization reports glaucoma as the second leading cause of blindness and the leading cause of irreversible blindness. Intraocular hypertension is the most relevant and only treatable risk factor for the disease. Non-invasive intraocular-pressure (IOP) measurements, carried out using eye tonometers, are used to screen for the intraocular hypertension. A correct measurement of the IOP is essential in the prevention and the fight against glaucoma. The authors present their work towards ensuring on one side the accuracy of IOP measurements for contact and non-contact tonometers in the Central European region and obtaining a harmonization of the requirements for IOP metrology at national level.
