(1) During the corneal tonometry it is very difficult to prevent the increasing of orbicular and palpebral muscles tone at the moment of measuring in reactive patients, that leads to IOP increasing.

(2) The tonometry result appears on the display and is preserved for 30 seconds followed by the tonometer's turning OFF automatically.

(3) Keeping the device in vertical position during tonometry provides optimal characteristics of the rod movement that increases measuring accuracy .

(4) Arterial tonometry allows the assessment of large artery stiffness and central pressure(), including central pulse pressure and various markers of wave reflections.

(5) Tonometry is the measure of intraocular pressure. Measurement of intraocular pressure plays an important role in the detection and management of glaucomatous conditions.

(6) The rhythmic fluctuations of blood filling and casual changes of the muscle tone explain difference between results of IOP successive measurings during tonometry .

(7) Methods:Measure the intraocular pressure of 70 patients (140 eyes) by dynamic contour tonometry and use comprehensive nursing at the same time.

(8) AIM: To determine the influence of topical anaesthetic drops, age and central corneal thickness (CCT) in the determination of intraocular pressure (IOP) by non contact tonometry (NCT).

(9) Unreliable IOP measuring with the tonometer is mainly connected with nonobservance of the tonometry 's methodology and with inadequate researcher's experience.

(10) Disinfection of the tip base and the rod should be carried out both before each patient's tonometry and after.
