Glaucoma: The Silent Thief of Sight

You’ve probably heard of glaucoma, but did you know it’s one of the leading causes of blindness around the world? What makes it especially tricky is that it often sneaks up without any warning signs — earning it the nickname, “the silent thief of sight.” The good news? With regular eye checkups and proper care, glaucoma can be managed before it causes serious vision loss.

What Exactly Is Glaucoma?

Glaucoma isn’t just one disease — it’s actually a group of eye conditions that damage the optic nerve, the part of your eye that sends what you see to your brain. When this nerve gets damaged, your vision starts to fade, often beginning with your side (or peripheral) vision.

This damage usually happens when pressure builds up inside your eye. Normally, a fluid called aqueous humor flows in and out to keep everything balanced. But if that fluid can’t drain properly, pressure increases and puts stress on your optic nerve. Over time, that can lead to permanent vision loss.

The Different Types of Glaucoma

There are two main types of glaucoma:

• Open-angle glaucoma: The most common form. The drainage angle in your eye stays open, but fluid drains too slowly. This kind develops gradually — you might not notice any vision changes until the damage is significant.

• Angle-closure glaucoma: Less common but more serious. Here, the drainage angle suddenly gets blocked, causing eye pressure to rise quickly. It can cause symptoms like severe eye pain, headaches, blurred vision, or nausea. This is a medical emergency — if it happens, see a doctor right away!

Who’s at Risk?

Glaucoma can affect anyone, but some people are at higher risk. You might be more likely to develop it if you:

• Are over 40 (and especially over 60)

• Have a family history of glaucoma

• Are of African, Asian, or Hispanic descent

• Have diabetes or high blood pressure

• Have had an eye injury

• Use steroid medications long-term

Because early stages often have no symptoms, regular eye exams are the best way to catch glaucoma early.

How Is It Treated?

There’s no cure for glaucoma yet, but treatments can help protect your remaining vision. Common options include:

• Prescription eye drops to lower eye pressure

• Laser treatments to improve fluid flow

• Surgery to create a new drainage pathway

The key is staying consistent with your treatment and keeping up with your eye doctor visits.

Protecting Your Sight

If you’ve been diagnosed with glaucoma, remember — you’re not alone, and vision loss can be slowed or prevented with proper care. Stick to your treatment plan, eat well, exercise regularly, and wear protective eyewear when needed.

And if you haven’t had an eye exam in a while, now’s the perfect time to book one. Catching glaucoma early could literally save your sight.

Top Five Signs You Need a Comprehensive Eye Exam

Our eyes are among our most important senses, yet they’re often taken for granted until something feels “off.” Unlike a simple vision screening, a comprehensive eye exam goes beyond checking if you need glasses—it evaluates the overall health of your eyes and can even detect early signs of systemic health conditions like diabetes or hypertension. So how do you know when it’s time to schedule one? Here are the top five signs.

1. Blurry or Fluctuating Vision

If you find yourself squinting to read road signs, struggling with computer screens, or noticing that your vision seems clear one moment and fuzzy the next, it’s time to get checked. Blurry or fluctuating vision may be caused by uncorrected refractive errors such as nearsightedness, farsightedness, or astigmatism. But it can also be linked to more serious conditions like cataracts, glaucoma, or even changes in blood sugar. An eye exam can pinpoint the cause and provide solutions to restore clarity.

2. Frequent Headaches or Eye Strain

Headaches aren’t always caused by stress or dehydration—sometimes they stem from your eyes working overtime. Straining to focus, especially while reading, driving, or using digital devices, can lead to discomfort in both your eyes and your head. This is often a sign of uncorrected vision problems or eye misalignment. A comprehensive exam not only determines if glasses or contact lenses can help but also checks for underlying eye coordination issues that may be contributing to the strain.

3. Difficulty with Night Vision

If driving at night has become increasingly uncomfortable—whether due to glare from headlights, halos around lights, or general difficulty seeing in low-light conditions—it’s a clear sign that you should schedule an eye exam. Trouble with night vision can indicate cataracts, early macular degeneration, or simply an outdated prescription. Addressing this issue promptly helps keep both you and others safe on the road.

4. Sudden Changes in Vision

Sudden blurriness, flashes of light, new floaters, or loss of vision in one or both eyes should never be ignored. These symptoms could point to serious problems such as retinal detachment, stroke, or other urgent eye conditions that require immediate medical attention. Even if the symptoms seem to improve, it’s crucial to have your eyes evaluated as quickly as possible.

5. It’s Been More Than a Year (or Two)

Even if you aren’t experiencing any obvious issues, regular eye exams are essential. Adults should generally have their eyes examined every one to two years, depending on age, risk factors, and whether they wear corrective lenses. Eye doctors can detect conditions like glaucoma or diabetic retinopathy long before symptoms appear—when treatment is most effective. Think of an eye exam as preventive care, not just a reaction to problems.

The Bottom Line

Your eyes do more than help you see—they provide a window into your overall health. If you’ve noticed any of the above signs, or if it’s simply been a while since your last exam, now is the perfect time to schedule a comprehensive eye exam. Protecting your vision today means preserving it for the years ahead.

The Benefits of a Visual Fields Test: Protecting Your Eye Health

What Is a Visual Fields Test?

A visual fields test measures both central and peripheral (side) vision. During the test, you’ll focus on a central point inside a machine while small lights or shapes briefly appear in different areas. Your responses help your eye doctor map your full range of vision, identifying strong areas and any blind spots.

Benefits of a Visual Fields Test

1. Early Detection of Eye Diseases

A visual fields test can reveal conditions like glaucoma, retinal disease, and optic nerve damage before symptoms become noticeable. Since peripheral vision loss often goes unnoticed, the test acts as an early warning system, allowing for treatment that can slow or prevent vision loss.

2. Monitoring Neurological Health

Your vision isn’t just about your eyes—it’s connected to your brain. A visual fields test can uncover signs of strokes, brain tumors, or neurological disorders that cause specific vision patterns. In some cases, this exam has even prompted life-saving diagnoses.

3. Tracking Vision Changes Over Time

For patients already managing glaucoma or other conditions, visual fields testing provides a reliable way to monitor changes. By comparing results over time, eye doctors can adjust treatments such as medication, laser procedures, or surgery to best protect your vision.

4. Supporting Everyday Safety and Independence

Peripheral vision loss can impact daily life—driving, walking safely, or navigating crowded spaces all rely on strong side vision. This test helps detect subtle changes early, giving patients a chance to adapt and stay independent.

5. Quick, Comfortable, and Painless

Unlike other medical tests, the visual fields exam is fast, non-invasive, and painless. Each eye is tested in just a few minutes, providing valuable insights with minimal effort.

Why You Should Ask About a Visual Fields Test

A visual fields test is more than an add-on to your annual eye exam—it’s a critical tool for maintaining vision and detecting serious health issues early. Whether you want peace of mind, need to monitor an existing condition, or simply want a full picture of your eye health, this test is worth discussing with your provider.
