Does Eye Pressure Fluctuate? What Most Glaucoma Patients Miss

The short answer: yes, eye pressure fluctuates. In fact, research shows that 83% of intraocular pressure (IOP) fluctuations happen outside of regular office hours. That means most in-clinic checks miss the pressure changes that matter most.

If you’re relying only on in-office measurements to manage glaucoma, you could be missing critical data that affects diagnosis and treatment. Fortunately, there’s a better way: home monitoring with the iCare HOME2 eye pressure device.

Why Eye Pressure Fluctuations Matter

Eye pressure isn’t constant. It rises and falls throughout the day, and many of the most dangerous eye pressure fluctuations occur outside clinic hours. These missed highs and lows can lead to inaccurate assessments and treatment plans that don’t match your real-world eye health.

The iCare HOME2 Tonometer: A Game-Changer in IOP Monitoring

Cleared by the FDA in 2022, the iCare HOME2 is a modern rebound tonometer designed for home use. It empowers patients to measure their own eye pressure throughout the day as eye pressure fluctuates. That allows you to capture the IOP spikes that clinic snapshots often miss.

• Easy to use with minimal training
• Designed for real-life daily tracking
• You can share data directly with your eye care provider

Catch Eye Pressure Fluctuations with a Tonometer

A study co-authored by Dr. Barbara Wirostko, Clinical Adjunct Professor at the Moran Eye Center and co-founder of MyEyes, confirmed the value of capturing eye pressure fluctuations at home.

Published in Glaucoma Today (Nov/Dec 2024), the paper titled “Impact of Selective Laser Trabeculoplasty on Diurnal IOP Fluctuations” found:

• 83% of eye pressure fluctuations occurred outside of office hours — only home monitoring captured them
• 96% of patients successfully used the iCare HOME2 eye pressure meter, showing it’s easy to operate with minimal training
• Provides doctors with real-world data that in-office visits often miss
• Helps personalize treatment plans by showing when and how eye pressures fluctuates during the day
