Tonometry

Tonometry is the measure of intraocular pressure. There are several methods used to obtain intraocular pressure, such as Goldmann applanation tonometry, Tono-Pen tonometry, pneumotonometry, and tactile tension. All these methods have advantages and disadvantages. Measurement of intraocular pressure plays an important role in the detection and management of glaucomatous conditions. It is important that the examiner be aware of the various methods and their shortcomings to obtain the most accurate measurement. By obtaining the most accurate intraocular pressure by tonometry, the diagnosis and management of glaucoma can be enhanced.
