Visual Fields

The visual field test analyzes your peripheral (side) vision.

How to Prepare

Please arrive for this outpatient procedure at the time and location given to you.

This test requires no special preparation. You may eat and drink as usual and remain active right up until the time of your appointment.

What to Expect

A technologist will ask you to sit in a chair and will cover one of your eyes with a patch. You will be asked to use your uncovered eye to look at a colored light on a screen while small, white lights flicker on and off on different parts of the screen. You will also be asked to press a button or tell the technologist each time you see one of the small lights flicker. The test will be repeated with your other eye covered.

The visual fields test takes approximately 20 to 45 minutes. You may resume your normal activities immediately.
