Why Early Glaucoma Detection Matters: The Importance of Routine Eye Exams

Glaucoma is one of the leading causes of permanent vision loss around the world. Known as the “silent thief of sight,” it often develops without symptoms until the damage is already advanced. That’s why routine glaucoma evaluation in Calgary is critical for early detection and timely treatment. Regular eye assessments are not just for updating your glasses—they play a vital role in preventing vision loss from eye diseases that show no early warning signs.

What is Glaucoma?

A collection of eye conditions known as glaucoma damages the optic nerve, typically due to a buildup of pressure inside the eye. Over time, this pressure can impair the nerve fibers that send images to the brain, potentially causing irreversible vision loss if not addressed promptly.

There are different types of glaucoma, including open-angle and angle-closure glaucoma. Open-angle is the most common type and progresses very slowly. Many patients don’t realize they have it until peripheral vision starts to fade.

Why Early Detection is Crucial

The damage from glaucoma cannot be reversed. However, if caught early, further damage can be slowed or even stopped with proper treatment. That’s why early diagnosis is so important. Once you start losing vision, that loss is permanent.

Routine eye care appointments give your optometrist the chance to monitor any early signs of glaucoma before vision loss occurs. Diagnostic tools like visual field tests, tonometry (to measure eye pressure), and optical coherence tomography (OCT) help detect glaucoma even in its earliest stages.

Common Risk Factors

Anyone can develop glaucoma, but certain people are at higher risk. These include:

• Adults over the age of 40
• Those with a family history of glaucoma
• Individuals with high eye pressure (intraocular pressure)
• People with diabetes, high blood pressure, or other chronic health conditions
• Patients with thin corneas
• Those with a history of eye injuries or steroid use

Even if you don’t have symptoms, it’s important to discuss your risk factors during your eye exam with a Seton optometrist. They can determine how often you should be screened based on your risk level.

Warning Signs to Watch For

In most cases, glaucoma shows no symptoms in the early stages. However, as the disease progresses, you might begin to notice:

• Gradual loss of peripheral (side) vision
• Blurred vision
• Eye pain or pressure
• Seeing halos around lights
• Tunnel vision in advanced stages

Sudden eye pain and rapid vision loss may signal a type of glaucoma that requires emergency care. If you notice any of these symptoms, don’t wait—seek immediate attention.

How Often Should You Get Checked?

Your eye assessment schedule depends on your age, medical history, and risk factors. In general:

• Adults aged 18–39 should have an eye exam every 2–3 years
• Adults aged 40–64 should go every 2 years
• Adults 65 and older should have yearly eye exams

If you have diabetes, a family history of glaucoma, or any other risk factors, your optometrist may recommend more frequent visits. Regular exams are the only reliable way to identify changes in your eye health early.

What to Expect During a Glaucoma Evaluation

A thorough glaucoma assessment involves several non-invasive tests. Your optometrist may perform:

• Tonometry: Measures the pressure inside your eye
• Visual Field Test: Assesses your side vision, where early glaucoma damage often occurs
• OCT Scan: Creates detailed images of the optic nerve and retina
• Gonioscopy: Evaluate the drainage angle in your eye
• Dilated Eye Assessment: Provides a better view of the optic nerve and internal eye structures

These tests help your provider diagnose glaucoma, monitor its progression, and decide on a treatment plan if needed.

Treatment Options for Glaucoma

If you’re diagnosed early, treatment can often prevent further damage. Common options include:

• Prescription Eye Drops: Lowers pressure inside the eye
• Oral Medications: Used when drops alone aren’t enough
• Laser Therapy: Improves fluid drainage to lower eye pressure
• Surgical Procedures: Used in advanced cases or when other treatments fail

Your optometrist or ophthalmologist will help choose the treatment that fits your condition and lifestyle.

The Role of Regular Eye Care

Maintaining consistent eye care helps preserve your vision and overall eye health. Eye exams do more than check how well you can see—they help spot signs of serious problems before symptoms appear.

Even if you don’t wear glasses or contacts, regular eye exams are important. Catching glaucoma early could mean the difference between clear vision and permanent vision loss.

Final Thoughts

Glaucoma is a lifelong condition, but with early detection and proper treatment, its effects can be managed. Skipping eye exams might save time in the short term, but it could cost you your sight later. Visiting Premier Eye Care – Seton for your routine eye checkups ensures that your eye health is always a priority.
