Visual Field Testing

A visual field test evaluates the side vision by flashing dim lights in the periphery of the vision. The patient is then asked to push a button with each light that s/he detects.In this manner we can determine whether there are any problems with the peripheral vision. Certain conditions require periodic visual field testing. For this test the eyes are not dilated, and we will need to know your current eyeglass prescription. This test takes about 20 minutes and is not uncomfortable.
