Diagnostic Testing: Visual Field Testing


What is it?

Visual field testing is performed to assess a patient's peripheral (side) vision. This is done in the clinic and is an automated test that requires approximately 20 minutes to complete. The testing process involves fixating your central vision on a target, and using your peripheral vision to react to light stimuli being projected onto various areas of your vision field.

What does it assess?

Visual field testing is most commonly used to assess glaucoma, however, it can also be used to assess damage to the optic nerve or neural pathways from other causes (such as tumours and strokes).
