Fields Test

 A visual field test is a test to measure your central and peripheral vision. Visual field testing actually maps the visual fields of each eye individually.

The most common visual field test uses a light spot that is repeatedly presented in different areas of your peripheral vision. It 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.

A visual field test is usually used to diagnose, determine the severity of, and monitor glaucoma. In addition to this, visual field tests are useful for detection of central or peripheral retinal disease, eyelid conditions such as ptosis or drooping, optic nerve disease, and diseases affecting the visual pathways within the brain.

Confrontation visual field testing typically is used as a screening visual field test. One eye is covered, while the other eye fixates on a target object, such as the opticians open eye, while the optician stands or sits directly in front of you. You then are asked to describe what you see on the far edges or periphery of your field of view. If an eye disease is suspected, you may need to undergo more comprehensive, formal types of visual field testing to evaluate the quality of your central and peripheral vision.
