    What is an Automated Visual Field Test?

    Your visual field is everything that you see. An Automated Visual Field test evaluates your vision straight ahead (central) as well as your vision to the side (peripheral). This test is important in the diagnosis of many eye disorders, especially glaucoma. Glaucoma is an eye disease usually associated with increased pressure within the eye which can cause a slow, painless, and permanent loss of vision.

    During this test, the technician will use computerized instruments to map out your visual field. Your pupils will not be dilated for this test. This test takes approximately 10-20 minutes per eye. An Automated Visual Field Test is also referred to as "Perimetry."
