Why do we do Visual Field Testing

Visual field testing is a common eye exam that is used to evaluate your peripheral vision, or the area outside of your direct line of sight. This test is important because it can help your doctor detect problems with your eyes that may not be apparent during a standard eye exam.

During a visual field test, you will be seated in front of a special machine called a perimeter. The perimeter will display a series of lights, and you will be asked to press a button every time you see one of the lights. The perimeter will measure how quickly you detect the lights and how accurately you respond, giving your doctor an idea of your overall visual field.

Visual field testing is a simple and painless procedure that typically takes about 20 minutes to complete. However, it can be slightly uncomfortable if you have a condition that affects your eyes, such as glaucoma. In this case, your doctor may use a different type of test to evaluate your visual field.

There are several reasons why your doctor may recommend visual field testing. For example, if you have a condition that affects your eyes, such as glaucoma or retinitis pigmentosa, your doctor may use this test to monitor the progression of the disease and determine the best course of treatment. In addition, visual field testing can also help your doctor diagnose problems with your eyes that may not be detectable during a standard eye exam, such as tumors or optic nerve damage.

Overall, visual field testing is an important part of maintaining your eye health. If your doctor recommends this test, be sure to follow their instructions and schedule an appointment as soon as possible. By detecting problems with your eyes early on, you can take steps to protect your vision and maintain your eye health
