Peripheral Vision Testing

Are you wondering how to get tested for peripheral vision loss? A visual field test is normally performed during a routine comprehensive eye exam. The next time you get your vision checked your optometrist will do a variety of tests including one to check your eyesight outside your normal or central field of vision.

Items may seem blurry, or out of focus, in your side field of vision but you still are able to recognize objects outside your normal line of sight. Problems with your peripheral vision are often an early sign of glaucoma. Anyone with a vision disorder such as glaucoma, cataracts or diabetic retinopathy has to get regular eyesight tests to make sure they don’t have any sudden changes in their vision.

Visual Field Test

A visual field test, to test peripheral vision, is called a variety of names including:

  • Visual field acuity test
  • Humphrey field exam
  • Goldmann visual field exam
  • Perimetry test
  • Automated perimetry
  • Tangent screen exam

A visual field test measures how far up and down and how far left and right your eyes see while your head and eyes remain stationary. Testing your visual field will help discover any blind spots in your vision. Blind spots are indicative of certain conditions, such as multiple sclerosis or macular degeneration, or medical problems including hypertension, stroke or brain tumours.

Types of Peripheral Vision Tests

There are various methods used to do a visual field test. A common method to test peripheral vision is getting the patient to cover one eye and focus on a central point in front of them. The examiner moves an object near the patients side field of vision. The patient lets the eye doctor know when they can see the object with their eye, then the test is repeated for the other eye.

More advanced test methods include the use of computerized instruments like the Humphrey field analyzer. An electronically assisted test can take up to 20 minutes to complete for each eye and isn’t always included in a normal vision check performed by an optometrist. More complex vision tests are typically completed by a medical doctor such as a Doctor of Ophthalmology or neuro-ophthalmologist.
