Visual Field Testing

Measuring the Range and Sensitivity of Your Field of Vision

What is Visual Field Testing

Visual field testing is a type of evaluation done to detect any dysfunction in the peripheral or central areas of vision. These dysfunctions can be caused by several different conditions, such as:

  • Brain tumor
  • Stroke
  • Glaucoma
  • Multiple sclerosis
  • Diabetes
  • Optic glioma
  • High blood pressure
  • Macular degeneration
  • Hyperthyroidism (overactive thyroid)
  • Temporal arteritis
  • Retinal detachment
How Does Testing Help?

Performing a visual field test can play an important role in the diagnosing of several important eye-related health conditions. Assessing any loss of vision will help your care team determine the right course of action to manage the underlying condition and its effects on your sight. Follow-up visual field testing might be performed to assess any changes to your sight following a course of treatment.

Important Information About Visual Field Testing:

How is visual field testing done?

This test is performed using a specialized computer controlled piece of equipment. Usually, one eye will be covered and the other eye must maintain fixation on a central target while light of varying intensity will appear throughout your field of view. You will click a button whenever you see a light and the machine will monitor which lights you can or cannot see to determine the range and sensitivity of your vision.
