A visual field test is a method in which our doctors measure your entire scope of vision. This testing is frequently used to detect any signs of glaucoma and also any detection of central or peripheral retinal disease. Other conditions such as ptosis (drooping of your eyelid), optic nerve disease, and diseases affecting the visual pathways within the brain are also reasons for visual field testing. The visual pathways carry information for the eye to the brain, where it is processed into vision.
A simple test can be done by having the patient look straight ahead and count the fingers shown by examiner from one side. However, at our offices we put you through a computerized assessment in which we cover one of your eyes, place your chin in a bowl-shaped chin rest, and give you a button to press when you see lights light up around you.
