Visual Field Testing
We often associate our vision with being able to see what’s directly in front of us. But your visual field spans to the corners of your eyes too. This is called peripheral vision and it’s needed to see what’s happening around you.
Measuring this part of your vision gives our ophthalmologists insight into your vision strength and vision loss. A visual field test may be the best way to find a solution that can halt vision loss.
What is a Visual Field Test?
Visual field testing is one way our team can evaluate your vision and determine if you have vision loss. For example, a visual field test can help detect blind spots in your vision. The size and shape of blind spots, called scotoma, can give insight into eye diseases or brain disorders affecting your vision.
Understanding Vision Screening Vs. Eye Exams
If you’re at risk for vision issues, disease, or loss then visual field testing should be a priority. It’s an effective way of detecting and monitoring conditions including:
The 6 Visual Field Tests
1. Confrontation Visual Field Test
2. Automated Static Perimetry Test
Your doctor will ask you to keep your eye on the center target throughout the test. Then, the doctor will test your vision by placing small, dim lights in the bowl. As you see the lights, you’ll press a button.
Some lights are dimmed to a point you can not see. This helps your doctor identify your visual threshold, so don’t be alarmed if you can’t see every light.
3. Kinetic Visual Test
4. Frequency Doubling Perimetry
The test will start with vertical bars appearing on the screen that flicker at varying rates. If you’re unable to see some of the bars during the test, you could be losing vision.
Your eye doctor will then ask you to focus on a bowl-shaped machine as it flashes light in varying patterns. The electrode device will then measure your eye’s response to light.
6. Amsler Grid
