applanation tonometry

Determining intraocular pressure by measuring the force necessary to flatten the corneal surface.

applanation tonometry

A standard method of measuring the pressure of the fluids within the eye by determining the force necessary to flatten a standard area of the CORNEA. Unduly raised pressure is the hallmark of GLAUCOMA.

These species-specific differences highlight the need for species-specific reference intervals, especially because reference intervals assessed for applanation tonometry cannot be transferred to rebound tonometry.

Goldmann applanation tonometry (GAT), the gold-standard method for the measurement of IOP, and related techniques such as NCT and TonoPen, use the Imbert-Fick principle to determine this value.

Factors affecting tonometry measurement

Patients with a raised pressure of >21mmHg after measurement by applanation tonometry are then referred to secondary care that is there is only one repeat IOP reading.

3) OHT is defined in the NICE glaucoma guidance as repeatable IOP over 21mmHg measured by Goldmann applanation tonometry (GAT), where optic discs and visual fields are normal.

2) This document, based largely on the evidence from major longitudinal studies, synopsised by the European Glaucoma Society, (3) states that patients should be offered Goldmann Applanation Tonometry (GAT) (Figure 1) for measurement of intraocular pressure (IOP) and pachymetry as part of the diagnostic process.
