At Corinth Eye Clinic and Weeden Eye Clinic, we may include visual field testing, also called perimetry, as part of your eye and vision exam. Your visual field is the entire area you can see when focusing on a central point, which includes your central vision, what’s in front of you, and your peripheral vision. Visual field testing allows our eye doctors to assess the extent of your central and peripheral vision and identify any potential blind spots or vision loss.
Visual field testing is essential to detect any blind spots or vision loss that may have occurred due to eye diseases. It helps us determine if there are any scotomas or blind spots in your visual field and pinpoint their location. Additionally, the size and shape of the blind spot can reveal how an eye disease or brain disorder is impacting your vision. For instance, if you have glaucoma, visual field testing will reveal any peripheral vision loss caused by the disease.
We understand the importance of visual field testing and how it can impact your overall eye health. That’s why our experienced eye doctors may recommend this test as part of your comprehensive eye exam. By detecting potential vision issues early on, we can provide you with prompt and effective treatment to help preserve your vision and maintain healthy eyes.
Types of visual field tests
Heru VR/AR Exam
Our eye doctors may utilize the Heru VR/AR exam wearable device during your eye exam. You’ll be able to sit upright throughout the testing process, while wearing the headset, and a built-in digital guide will lead you through the experience. The video on the left shows an example of what to expect when wearing the HERU VR/AR exam device.
Confrontation visual field test
During this test, you’ll cover one eye and focus on a fixed object while our eye doctor holds an object in your peripheral vision. We’ll ask you to identify the object to determine if there are any issues with your visual field. If further testing is needed, we may recommend more advanced visual field tests.
Automated perimetry test
This test creates a map of your visual field and is used to diagnose specific eye conditions or monitor an eye disease. You’ll be seated in front of a bowl-shaped device called a perimeter, and each eye will be tested separately. The device will have your optical prescription, and you’ll be instructed to keep your eye on a center target while lights flash in different areas of the bowl. You’ll press a button when you see the flashing lights, and a report will be compiled based on the lights you didn’t identify. This test measures your visual threshold, so you may not see all the flashing lights.
Frequency doubling perimetry
This test uses an optical illusion to detect loss of vision. Vertical black and white lines will flicker at different times and rates on a perimeter screen. If you can’t see the lines clearly, it may indicate vision loss in parts of your visual field.
Amsler grid
This test uses a pattern of straight lines to form a grid with equal squares. You’ll be asked to look at a dot in the middle of the grid and describe any lines or areas that appear wavy, blank, or blurry. This test is often used for people with age-related macular degeneration and can be done at home. While it only measures the middle of the visual field, it can still help monitor changes in vision.
At Corinth Eye Clinic/Weeden Eye Clinic, our experienced eye doctors will recommend the most appropriate visual field testing based on your specific needs. These tests are essential in detecting and monitoring eye conditions early, so you can receive prompt and effective treatment to maintain healthy eyes and preserve your vision.
