Glaucoma is one of the leading causes of permanent vision loss, often developing silently with no early symptoms. Because it can progress without pain or noticeable vision changes, early detection is the most effective way to protect your long-term eye health. One of the key factors your eye doctor in Waterloo, IA evaluates during a comprehensive exam is your intraocular pressure (IOP) - commonly referred to as eye pressure.
Inside the eye, a fluid called aqueous humor maintains shape and nourishes internal structures. This fluid drains through a natural filtration system to keep eye pressure balanced. When something disrupts this drainage - whether from age, genetics, or other factors - eye pressure can rise.
While elevated eye pressure doesn’t automatically mean you have glaucoma, it is one of the most important risk factors your doctor evaluates. Monitoring IOP regularly helps identify early signs of pressure imbalance that may lead to optic nerve damage.
Glaucoma damages the optic nerve, and one of the strongest predictors of this damage is high eye pressure. However, the relationship is not always straightforward - some people develop glaucoma with normal pressure, while others with high pressure never develop the disease. This is why professional testing and monitoring are essential.
During glaucoma exams in Waterloo, we rely on more than just pressure measurements. A full evaluation often includes:
• Tonometry to measure intraocular pressure
• Optic nerve imaging using advanced diagnostic technology
• Visual field testing to assess peripheral vision
• Corneal thickness measurements, which can affect the accuracy of pressure readings
By combining these tests, Dr. Egan creates a complete picture of your eye health so that early signs of glaucoma can be caught long before symptoms appear.
Today’s glaucoma testing is more precise than ever. We use modern diagnostic tools that measure eye pressure gently and accurately, without the discomfort older methods sometimes caused. Imaging systems such as OCT (optical coherence tomography) allow us to detect microscopic changes in the optic nerve - even before vision loss begins.
Because glaucoma progresses silently, many people do not realize they are at risk. Even those with normal eye pressure can still develop the condition, which is why regular exams are important for all adults - especially if you have:
• A family history of glaucoma
• Diabetes
• High blood pressure
• A history of eye trauma
• Age over 60
Dr. Egan can help determine how frequently you should schedule glaucoma screenings and what preventive steps you can take to protect your vision.
Eye pressure is a critical piece of the puzzle in detecting glaucoma, but it’s only one part of a complete evaluation. With advanced technology, careful monitoring, and comprehensive exams, we provide the early detection and personalized care needed to safeguard your eyesight for years to come.
