   What is a normal visual field test?

   • A normal visual field measures about: One eye is tested at a time. This is because the visual fields of the eyes overlap. Visual pathways carry information from the eye to the visual part of the brain. There, the information is processed into vision. A visual field test measures how well you can see above, below, and on either side of you.

   • Nonspecific / low Reliability / inattention / patient hungry. For every interpretable, reliable visual field you get, you will also get another in which the patient thinks he should be scanning the dome for lights the whole time, is poorly positioned, is exhausted from waiting in your clinic for hours, or is too elderly and arthritic to push the button in time.
   • Superior / inferior arcuate defect. The most common early to mid stage glaucomatous field. The reason these look like arcs and come off the blind spot is that they represent the loss of bundles of nerves as they come out of the optic nerve head.
   • Blind spot enlargement. This can be seen in glaucoma, but also can occur with papilledema and optic nerve head swelling. This would likely be seen in patients with idiopathic intracranial hypertension (aka pseudotumor cerebri).
   • Severe constriction with a central island. Unfortunately, this is end stage glaucoma. At this point, many patients still have great central vision of 20/20 to 20/50, but peripheral vision is nearly gone.
