What Does Tonometry Help With?

Tonometry is the name given to a range of methods and medical devices that measure the intraocular pressure (IOP) of the fluid inside the eye. It is an essential indicator of overall eye health. IOP measurement is a routine part of examinations and is crucial in the early detection of conditions such as glaucoma and ocular hypertension.

 

Tonometry equipment supports several IOP measurement methods. Applanation tonometry, also known as the Goldmann method, flattens the cornea, while non-contact tonometry uses a controlled puff of air to assess IOP without corneal contact. Rebound tonometry uses a small disposable probe that briefly contacts the cornea, often without the need for anaesthetic drops, allowing a degree of extra patient comfort.

 

If you’re looking for a more detailed explanation of what a tonometer is and how different devices work, our expert guide covers the main methods in more detail.

Frequently Asked Questions

What is tonometry?

Tonometry is the clinical measurement of intraocular pressure (IOP) using specialised tonometry instruments. These devices are used in optometric and ophthalmic settings to support screening, monitoring and assessment of pressure-related eye conditions. It is commonly used in the early detection of conditions such as glaucoma and ocular hypertension, where excess pressure can cause optic nerve damage.

The ability for patients to measure their own IOP has the potential to transform glaucoma care. By using home monitoring, we can obtain far more IOP measurements to more accurately identify peak IOP and gain greater appreciation of IOP fluctuations.

Most patients find iCare HOME easy to use and as IOP measurements can be uploaded to the cloud, the clinician can view results remotely. In my practice, the introduction of iCare HOME has allowed us to move away from office-hour IOP phasing and has provided improved insight into IOP as a risk factor for glaucoma progression.
