Testing for Glaucoma: How Early Detection Can Save Your Sight

Glaucoma is one of the leading causes of irreversible vision loss around the world. Often called the silent thief of sight, it can slowly damage the optic nerve without any noticeable symptoms until significant vision has already been lost. Fortunately, early detection through comprehensive eye exams can help preserve your vision and prevent long term damage.

What Is Glaucoma?

Glaucoma is a group of eye diseases that damage the optic nerve, the part of the eye responsible for transmitting visual information to the brain. This damage is often associated with elevated intraocular pressure, though glaucoma can also occur with normal eye pressure. The most common types are open angle glaucoma and angle closure glaucoma, each with distinct characteristics but both potentially leading to permanent vision loss.

Why Early Detection Matters

One of the most dangerous aspects of glaucoma is that it usually develops without pain or immediate symptoms. By the time a person notices a change in their vision, the damage may already be advanced. Since lost vision cannot be restored, catching the disease in its early stages is critical for protecting your eyesight.

Routine eye exams are the most effective way to detect glaucoma before symptoms appear. These tests allow eye doctors to monitor changes in the optic nerve, measure intraocular pressure, and assess your field of vision.

How Is Glaucoma Tested?

At Texas State Optical, our glaucoma testing is part of a comprehensive eye exam and may include several key evaluations:
 

• Tonometry: This test measures the pressure inside your eye. Elevated intraocular pressure is a significant risk factor for glaucoma.

• Ophthalmoscopy: Using special instruments, we examine the optic nerve for signs of damage.

• Perimetry: Also known as a visual field test, this assesses your peripheral vision and helps identify any vision loss.

• Pachymetry: This measures the thickness of your cornea, which can influence eye pressure readings.

• Optical Coherence Tomography (OCT): This advanced imaging technology provides a detailed view of the optic nerve to detect even the smallest changes over time.

Who Is at Risk?

While anyone can develop glaucoma, certain individuals are at a higher risk, including:
 

• Adults over the age of 60

• People with a family history of glaucoma

• Individuals with diabetes or high blood pressure

• African American, Hispanic, and Asian populations

• Those with high eye pressure or thin corneas

If you fall into any of these categories, regular eye exams are even more important.

Schedule Your Glaucoma Screening Today

Glaucoma cannot be cured, but it can be managed. With early detection, treatment such as prescription eye drops, laser therapy, or surgery can help slow or prevent further vision loss. The key is to catch it before symptoms begin. We are committed to protecting your eye health with advanced diagnostic tools and personalized care.
