A visual field test is a method of measuring an individual’s entire scope of vision, that is their central and peripheral (side) vision. This automated instrument actually maps the visual fields of each eye individually. This test is a subjective examination, requiring the patient to understand the testing instructions, fully cooperate, and complete the entire test in order to provide useful information.
Visual field testing is most frequently used to detect any signs of glaucoma damage to the optic nerve. In addition, visual field tests are useful for detection of central or peripheral retinal disease, eyelid conditions such as drooping, optic nerve disease, and diseases affecting the visual pathways within the brain.
This test may be ordered by Dr. Ashley Pulis for various reasons. It takes approximately 15-20 minutes and is non-invasive. Our staff strives to make the testing process as easy and comfortable as possible.
