Visual Field

A visual field test is a way to measure your visual field, or how much you can see to each side while focusing your eyes on a central point  The patient will focus on one central point while a series of lights flash all around them, clicking on the indicator as they see them flash.

Although many patients mistake it as simply a peripheral vision test, a visual field test is actually designed to measure the overall field of vision as it is interpreted by the brain in four neurological quadrants. It is measured with an automated perimeter, a computerized device that collects your data and compares it to normal.

This test is another part of Dr. Looysen's comprehensive eye health exam that will enable him to determine the extent of macular degeneration.
