What do the results of the visual field test mean?
A "normal" visual field test means that the patient can see about as well as anyone else does in the center and around the edges of the visual field.
A test that shows visual field loss means that vision in some areas is not as sensitive as normal. It could be just a little vision lost in a small area, or all vision lost in large areas.
The amount of vision lost and the areas affected are measured by the visual field test. These results are printed out by the instrument as patterns of dots or numbers. The patterns tell the doctor a lot about how the eye and the visual field system are working. This helps your doctor decide whether you have a health problem that needs additional testing to be diagnosed or if treatment is recommended.
