Visual Field Testing
Visual Field Testing
The term visual field refers to the entire area you can see while looking at a fixed location. For example, while watching a stoplight, you might notice a car pulling up beside you in the next lane. Your peripheral vision enables you to see the movement of the car. The visual field is large when both eyes are working properly. With glaucoma, the field of view is often reduced. The visual field is measured using an instrument called a perimeter.
If you have glaucoma and some loss of visual field is present, your condition will be followed carefully with repeated testing to determine whether the problem has been halted or if further loss is occurring. The time interval between visual field tests depends on many different factors and is best determined by your eye doctor. Regular examinations are very important for the proper management of your glaucoma.
