Visual Field Exam - Medical Test
Visual Field Exam
An exam to check your field of vision (the total area in which you can see objects around you). This test measures both central vision (how much a person can see when looking straight ahead) and peripheral vision (how much a person can see in all other directions while staring straight ahead). Any loss of vision may be a sign of a tumor that has damaged or pressed on the parts of the brain that affect eyesight.
