Eye pressure self-monitoring made easy: understanding glaucoma IOP and using a tonometer at home

iCare HOME2

Your eyesight is precious. Yet conditions like glaucoma—a leading cause of irreversible blindness—pose a serious threat to it. Elevated intraocular pressure (IOP), a major risk factor for glaucoma and other eye issues, makes regular testing essential for early detection and effective monitoring. Thanks to iCare HOME2 tonometer, eye pressure self-monitoring can be conveniently done at home.

IOP monitoring is essential for continuing eye care

An eye pressure measurement, or IOP test, is used to monitor the pressure within the eyes. Your eyes contain a fluid known as aqueous humor that nourishes the eye. Usually, this fluid drains smoothly, but sometimes, the system can get clogged or fail to drain properly. As a result, the fluid builds up, creating pressure inside the eyes.

High pressure can also be caused by an eye injury, which might damage the draining system and increase the pressure, potentially many years after the initial damage.

Elevated eye pressure doesn’t automatically mean a condition like glaucoma, but if your eyes experience high pressure over an extended period, it can damage your optic nerve. This is why regular IOP monitoring and its support for early detection is essential. Monitoring is especially crucial if you have already been diagnosed with glaucoma or suffered an eye injury.

Eye pressure testing with unparalleled comfort and ease of use

IOP is measured using diagnostic instruments called tonometers. They allow eye care providers to verify if the eye pressure is at a normal level and, when used regularly, help determine whether the pressure fluctuates too much. The tonometer’s reading gives your doctor an indication if you are at risk of developing conditions such as glaucoma or whether your condition is progressing.

In 2003, iCare developed a method using rebound tonometry, a non-invasive method which, unlike other methods, does not require anesthetic eye drops or puffs of air. In the iCare method, a tiny disposable probe makes six quick contacts with the eye.

For over 20 years, this method of measuring IOP in a clinical setting has been popular with both doctors and patients, thanks to its accuracy, reliability and ease of use.

Intraocular pressure tends to fluctuate throughout the day and night, with variations in glaucoma patients averaging three times higher than in normal eyes. Because of this, measuring IOP only a few times a year at a clinic is often insufficient, as IOP peaks frequently occur outside of office hours. Until recently, measuring IOP outside of clinical settings was nearly impossible, as specialized equipment could only be found in medical facilities. Luckily there now exists a solution.

iCare HOME2 is a self-tonometer that allows you to measure and monitor your IOP anytime, anywhere. It is based on the same widely patented rebound principle as other iCare tonometers and has been validated in numerous clinical studies.

Accurate, real-world IOP trends, provided by the HOME2, support your doctors in making informed care decisions. Access to extensive IOP data enables your doctor to assess the effectiveness of prescribed medications or past eye surgeries, helping them personalize your glaucoma care to better meet your needs.
