Why Regular Glaucoma Screenings Are Important
Glaucoma screening is a group of simple tests that look for early, silent damage to the optic nerve. It checks pressure, structure, and function, so changes are found before vision is affected. Seeing an optometrist in Seton for regular screening helps build a baseline, compare results over time, and respond quickly if risk appears.
How Screenings Catch Problems Before Symptoms Start
Glaucoma often develops without warning. You may see well for years while small changes progress in the background. Screening closes that gap. Your eye doctor compares current and prior results to spot trends, even when day-to-day vision feels the same. This approach allows earlier action and a clear plan.
Glaucoma Screening (Quick Reference)
- Goal: Find optic nerve damage early, often before symptoms.
- Core Measures: Intraocular pressure, optic nerve structure, and visual field.
- Who Benefits: Adults over 40 or anyone with glaucoma risk factors.
- Timing: Every 1–2 years for most; more often with higher risk.
- Result: A tailored plan for monitoring, treatment, or referral.
Who Needs More Frequent Screening
When these risks are present, shorter review intervals help us catch subtle changes while they are still easy to manage:
- Age over 60 (earlier for some groups)
- First-degree relatives with glaucoma
- Thin corneas, high myopia, or past eye injury
- Long-term steroid use
- Systemic conditions such as diabetes
Many families in Calgary’s southeast plan visits around work and school; keeping a steady schedule at the same centre improves comparisons over time.
What Tests Are Typically Included
A thorough screening may include:
- Tonometry: Measures intraocular pressure to gauge optic nerve pressure risk.
- Optic Nerve Assessment: Dilated evaluation and OCT imaging to map the retinal nerve fibre layer and the nerve head.
- Visual Field Testing: Checks peripheral vision for functional change.
- Pachymetry: Measures corneal thickness, which affects pressure readings.
- Gonioscopy (when indicated): Examines the drainage angle to guide management.
No single test tells the whole story. Your doctor looks at all measurements together to understand how the optic nerve is coping over time.
How Early Detection Helps Prevent Vision Loss
The main goal is to protect the optic nerve by lowering pressure to a safer range. Early glaucoma detection expands options, including medicated drops, laser procedures, or surgery when appropriate. Just as important, scheduled reviews confirm that treatment is working and allow timely adjustments if measurements drift.
How Often Should Different Age Groups Book
- Under 40: Every 2–3 years if healthy; sooner with risk.
- Ages 40–60: Every 1–2 years, adjusted to history and findings.
- Over 60: Every year, or as advised by your eye doctor.
In our dry Canadian winters, eyes can feel different from season to season. Regular visits help ensure your plan stays steady year-round. If you are catching up after a busy stretch, the team can help you book glaucoma test times that fit your routine.
Recognizing Changes (Even If You Feel Fine)
Most people notice nothing early on. Later optic nerve damage signs may include patchy blind spots, trouble seeing in dim light, or narrowing of side vision. Because these usually appear late, routine glaucoma screening is safer than waiting for symptoms.
When To See An Eye Doctor
Seek care promptly if you notice:
- Sudden blurred or double vision
- Eye pain, a feeling of pressure, or halos around lights
- Headache with eye discomfort
- Flashes of light, new floaters, or any sudden change in vision
Routine visits are also important if you have risks or a family history.
FAQs
Yes. Early disease is often symptom-free. Screening checks for changes before daily tasks are affected.
They are generally well tolerated. You may feel a brief puff of air or receive numbing drops for contact methods.
Coverage varies. Many plans support medical assessments when risk factors or findings are present. Confirm your benefits before booking.
Usually, yes. If your eyes are dilated, expect light sensitivity and blurred near vision for a few hours. Sunglasses help.
Fees depend on the test bundle and your coverage. Clinics can provide a range of help and help you use your plan effectively.
Your doctor may repeat tests, shorten the follow-up interval, or start pressure-lowering treatment if trends suggest risk.
