Visual field testing helps determine where your peripheral vision begins and ends
What We Test For
Visual field testing may be required for any of the following reasons:
To detect damage to the optic nerve from conditions such as glaucoma
To monitor glaucoma
To obtain a baseline reading for future testing
To detect any issues with the visual pathway leading to the brain
To assess the visual field due to a neurological condition
How It's Conducted
The test will involve looking at a central fixation point and responding to the appearance of a brief flash of light in your peripheral vision. The test is usually conducted in a darkened room, and you will be asked to look straight ahead at a central target. As the test progresses, the examiner will record your responses to flashes of light appearing in different parts of your visual field.
