About Glaucoma, “The Silent Thief of Sight”
Read on to learn why glaucoma is known as the “silent thief of sight,” what causes it, who is at risk, and the treatment options available. We’ll also share how our glaucoma specialists at Buffalo Ophthalmology can help protect your vision.
What Causes Glaucoma?
Glaucoma occurs when the pressure inside the eye (intraocular pressure, or IOP) becomes too high, damaging the optic nerve. This crucial link transmits images from your eyes to your brain. Over time, this damage results in a gradual and irreversible loss of peripheral (side) vision, and if left untreated, it can progress to complete blindness.
The most common type, open-angle glaucoma, develops slowly as eye pressure rises over time. Because vision changes happen so gradually, you may not realize anything is wrong until significant damage has occurred. This is why early detection through routine eye exams is critical, particularly if glaucoma runs in your family.
A less common but more urgent form is acute angle-closure glaucoma, where eye pressure rises suddenly and dramatically. This can cause intense eye pain, blurred vision, and severe headaches. It is a true medical emergency that requires immediate treatment to prevent blindness.
Risk Factors for Glaucoma
While glaucoma can affect anyone, certain factors increase the likelihood of developing it. You may be at higher risk if you:
- Have a family history of glaucoma
- Are over the age of 60
- Have diabetes, high blood pressure, or heart disease
- Have experienced eye injuries
Demographics also play a role. For example, African Americans are at significantly higher risk of developing open-angle glaucoma, often at an earlier age, and are up to six times more likely to experience vision loss from the disease compared to other groups.
Because risk factors vary, it’s important not to assume you are safe simply because you feel fine. Glaucoma doesn’t announce itself—you only find it with a comprehensive eye exam.
Signs and Symptoms to Watch For
Although glaucoma is often symptomless in its early stages, certain signs may suggest a more advanced case or acute angle-closure glaucoma.
These include:
- Severe or sudden eye pain
- Blurred or hazy vision
- Halos around lights
- Headaches accompanied by eye discomfort
- Loss of peripheral vision
If you experience any of these symptoms, seek medical care immediately.
Treatments for Glaucoma
Vision loss from glaucoma is permanent and cannot be reversed. However, if diagnosed early, treatment can slow or even halt its progression, preserving your remaining vision.
Some of the most common treatments include:
- Medicated eye drops – Often the first line of defense, these help lower intraocular pressure.
- Laser treatments – Office-based procedures that can improve fluid drainage from the eye.
- Minimally invasive glaucoma surgery (MIGS) – Surgical techniques designed to reduce pressure with quicker recovery times.
- Traditional glaucoma surgeries – Recommended in advanced cases or when other treatments are ineffective.
No treatment can restore vision already lost to glaucoma, which is why early detection is vital. Even if you don’t have obvious risk factors, a dilated eye exam every year gives you the best chance of catching glaucoma early enough to protect your eyesight.
Protecting Your Vision: Why Early Detection Matters
It’s easy to think of vision as something permanent, but glaucoma is a reminder of how fragile and precious it is. Because this disease develops quietly, routine eye care isn’t just recommended—it’s essential. By making eye exams a regular part of your health care, you give yourself the best chance to keep your vision clear and strong for years to come.
