Glaucoma is a leading cause of irreversible vision loss, and IOP measurement plays a central role in its detection and management. Over four million people in the United States have glaucoma, with nearly half unaware of the condition (Glaucoma Research Foundation). Measuring intraocular pressure (IOP) helps doctors identify risk early, track how glaucoma changes over […]
In glaucoma care, intraocular pressure testing plays a central role in guiding treatment decisions. Eye doctors rely on repeated pressure tests to determine whether medications are working, whether adjustments are needed, and how aggressively the disease should be managed over time. While IOP measurement explains what eye pressure is and how it’s measured, intraocular pressure […]
Measuring eye pressure, known as intraocular pressure (IOP), is one of the most important parts of a routine eye exam. Eye care professionals use tonometry to measure this quickly and painlessly. Two of the most common methods are rebound vs. air puff tonometry. Both tests help detect glaucoma early, but they work differently: one uses […]
Measuring eye pressure, or intraocular pressure (IOP), is the first step in detecting glaucoma. The process, known as tonometry, uses specialized instruments to measure the pressure inside your eye quickly and painlessly. Key Takeaways Types of Tonometry Tests Eye doctors use several types of tonometry to measure eye pressure. Each method works a little differently […]
Glaucoma is often misunderstood. But one thing is sure: it’s a leading cause of blindness worldwide. Unlike many conditions, glaucoma symptoms may not appear until significant, permanent vision loss has already taken place. In the U.S., 4.2 million people have glaucoma, and nearly half don’t know it (Glaucoma Research Foundation). It’s not a single disease, […]
This is a curated transcript from the MyEyes Webinar held on September 10th, 2025, titled:“Managing Eye Pressure & Stress: Proactive Glaucoma Care.” During the event, glaucoma specialists answered dozens of live questions from patients and caregivers. This Q&A captures those insights, organized by theme for more straightforward navigation. Personal identifiers and names have been removed, […]
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 […]
Most people never think about their eye pressure — until something goes wrong. But this one number can reveal a lot about your eye health. More importantly, it can predict your risk of glaucoma — a leading cause of permanent vision loss. According to Allied Eye, between 3 and 6 million people in the U.S. […]
By MyEyes With insights from Barbara M. Wirostko, MD, FARVO, a glaucoma specialist Glaucoma is one of the leading causes of irreversible blindness worldwide. Often called the “silent thief of sight,” it causes vision loss gradually, without warning. The main culprit? Increased eye pressure, also known as intraocular pressure (IOP). That’s why it’s essential to […]
Key Takeaways Introduction: Understanding the Importance of IOP Measurement If doctors diagnose you with glaucoma or if you are at risk, you must keep track of your eye pressure. Glaucoma is one of the leading causes of vision loss, and high IOP is a significant risk factor. Traditionally, doctors measure IOP during eye exams. However, […]
