Glaucoma Testing Explained: What to Expect at Your First Exam

Glaucoma is one of the leading causes of vision loss worldwide, often referred to as the “silent thief of sight” because it can progress without obvious symptoms in its early stages. At Texas State Optical, our goal is to make sure you know exactly what to expect at your first glaucoma exam and why it matters for your long-term eye health.
 

What Is Glaucoma and Who Is at Risk?

Glaucoma is a group of eye diseases that damage the optic nerve, the part of your eye responsible for sending signals to your brain so you can see. This damage is often related to high pressure inside the eye (intraocular pressure), though not always.

Anyone can develop glaucoma, but certain groups are at higher risk, including:

• Adults over age 40

• People with a family history of glaucoma

• African American, Hispanic, and Asian populations

• Individuals with diabetes or high blood pressure

•          Those who are very nearsighted or farsighted

If you fall into one of these categories, regular testing becomes even more essential.
 

Why You Need to Get Tested

Because glaucoma develops slowly and often without noticeable symptoms, many people don’t realize they have it until significant vision loss has occurred. Testing is the only reliable way to detect glaucoma early - before irreversible damage sets in.
 

What to Expect During Glaucoma Testing

When you come in for your first glaucoma exam, our doctors use several advanced tests to evaluate your eye health. Common tests include:

• Tonometry - measures your eye pressure.

• Ophthalmoscopy - allows your eye doctor to look at the optic nerve for signs of damage.

• Perimetry (Visual Field Test) - checks your peripheral vision to detect vision loss patterns.

• Pachymetry - measures the thickness of your cornea, which can affect eye pressure readings.

• Optical Coherence Tomography (OCT) - provides a detailed image of your optic nerve and retinal layers.

These tests are quick, painless, and give your optometrist a complete picture of your eye health.
 

How Often Should You Be Tested?

Most adults should have a comprehensive eye exam, including glaucoma testing, every year. If you have risk factors for glaucoma, your doctor may recommend more frequent exams to ensure early detection and proper monitoring.
 

Why Early Detection Is Crucial

Vision loss from glaucoma is permanent - but with early detection, the disease can be managed effectively to slow or even stop its progression. Regular testing gives you the best chance of protecting your sight for years to come.
