Visual Field Tests, Explained

Visual field tests may sound like they’re outdoor visual testing for your eyes — namely how much your eyes can tolerate during your normal outdoor stroll and measuring your capability to view things. However, these tests are mostly done indoors under the careful observation of your local eye doctor. Continue reading as Vienna Eyecare Center shares the basics of this type of eye examination.

Understanding Visual Field Testing

A visual field test measures the full horizontal and vertical range of what you can see peripherally while focusing your eyes on a central point. This test is essential for identifying any blind spots (scotomas) in your vision, which could be an indicator of various eye diseases or brain disorders. Professionals use visual field testing as a fundamental part of our diagnostic toolkit, given its effectiveness in detecting early signs of conditions such as glaucoma, where peripheral vision may be affected first.

The Importance of Visual Field Tests

These tests are not just about checking for blind spots; they are a non-invasive way to assess the potential presence of eye conditions that could lead to serious vision issues if not timely diagnosed and managed. Conditions like glaucoma, retinal damage or even optic nerve issues can impair vision, which can significantly impact one’s quality of life. Therefore, identifying such conditions early on through visual field testing allows for early intervention.

Types of Visual Field Tests

Eyecare providers, including us, employ several types of visual field tests, each designed to analyze different aspects of your visual field:

  • Automated Perimetry Test.  This test involves looking into a dome-shaped instrument (perimeter) and pressing a button each time you see a flash of light. This process maps out your entire field of vision, helping detect any areas where your vision may be compromised.
  • Kinetic Visual Field Test. This test is similar to the automated perimetry test, but it uses moving targets to determine the most peripheral limits of your vision. This test is particularly useful for identifying areas of vision loss.
  • Amsler Grid. For patients with concerns specifically about their central vision, often related to conditions like macular degeneration, the Amsler grid test is a simple yet effective tool. It involves looking at a grid pattern to identify any distortions or blind spots in the central visual field.

Preparing for Your Visual Field Test

When you come in for a visual field test, there’s no special preparation needed. However, inform your eye care professional about any current eye prescriptions or significant health changes since your last visit. The test is straightforward and painless, and understanding its process can help alleviate any concerns beforehand.
