Tonometers

Tonometers measure intraocular pressure in the eye. Accurate measurement of this pressure is important for diagnosing and managing glaucoma. They are available in many forms, from well-established instruments to newer, less invasive devices. Each one has its benefits and disadvantages and is used for different purposes and patient populations.

They come in a variety of styles and prices. Some are able to measure intraocular pressure without touching the eye. A new version of the Perkins Mark 2 Tonometer has an ergonomic design and a tonogrip prism holder.

Non-contact tonometry reduces the risk of transmission of disease to the eye. Non-contact tonometry uses the contour-matching principle and eliminates mechanical changes. Another new model is called a Dynamic Contour Tonometer, or DCT. This device is similar to a Goldmann applanation tonometer but is not a variable-force tonometer. They can be used to diagnose or treat various eye conditions. However, it can be a good option for a patient with a narrow range of IOP. There are different types of tonometers, including the GAT, the Non-contact Tonometer, and the Goldmann Applanation Tonometer. The latter uses a disposable metallic probe and colbalt blue filter. These methods are less invasive and more convenient. Non-contact tonometry is often used in pediatric care, and it is easy for doctors to perform it in children.

Non-contact one are needs to be cleaned and disinfected regularly. In general, non-contact tonometers underestimate high IOP and overestimate low IOP.

Handheld one can be used to measure IOP. They are portable and use a combination of applanation and indentation to measure the IOP. This device has a small plunger and a footplate that curves upward to contact the cornea. The weight of the plunger is adjustable from 5 to fifteen grams. The amount of indentation the tonometer creates is proportional to the IOP.
