Visual Field Test Services in Edmonton

Visual field testing is a valuable diagnostic tool that helps detect potential problems with your peripheral vision, allowing for early intervention and treatment. At Optometrists’ Clinic Inc., we offer visual field screening as part of our comprehensive eye care services. We use the most advanced testing equipment and techniques to ensure a swift diagnosis.

What is a Visual Field Test?

A visual field test assesses the full scope of your vision, including your peripheral vision. This painless, non-invasive procedure helps detect abnormalities in your field of vision that might indicate underlying eye conditions. It is also used to monitor the progression of some conditions, most commonly in glaucoma.

Peripheral Vision Loss

Peripheral vision loss is a condition where your side or “peripheral” vision is impaired. This condition can be caused by various factors, such as glaucoma, retinitis pigmentosa and optic nerve damage. Peripheral vision loss is often gradual and can go unnoticed until it significantly impacts your daily activities. Specialized visual field testing can detect very subtle changes in peripheral vision that you would never notice on your own until it is too late to intervene.

Conditions Requiring Visual Field Testing

Visual field screening can help diagnose and monitor various eye conditions, including:

Confrontation Test

Confrontation visual field test. The optometrist will cover one of your eyes and ask you to look straight ahead and focus on a target. They’ll then hold their hand in your field of view and ask how many fingers you can see.

Automated Perimetry Test

During this test, you’ll look into a machine and focus on a fixed point while a computerized instrument projects small lights at various intensities and locations within your peripheral vision. You’ll be asked to press a button whenever you see a light. The equipment maps out your responses, helping identify blind spots.

Kinetic Visual Field Testing

This is like an automated perimetry test, but the lights move, providing detailed insights into visual field abnormalities.

Frequency Doubling Perimetry Test

This specialized test uses optical illusions with black and white vertical bars to test for blind spots. It’s often used in screening tests.

Electro-retinography

This test involves using numbing eye drops and dilating your eyes to measure the retina’s electrical responses using flashing light patterns. This rarely used test can be used to diagnose various retinal disorders and requires a referral from your optometrist to an ophthalmologist to complete.

Amsler Grid Test

This is a tool the optometrist may suggest to self-monitor your central vision, especially if you have a condition like macular degeneration.
