Visual field testing is one way your ophthalmologist measures how much vision you have in either eye, and how much vision loss may have occurred over time.

Who Needs Visual Field Testing?

Visual field testing is an important part of regular eye care for people who are at risk for vision loss from disease and other problems. People with the following conditions should be monitored regularly by their ophthalmologist, who will determine how often visual field testing is needed:

• Glaucoma
• Multiple sclerosis
• Hyperthyroidism
• Pituitary gland disorders
• Central nervous system problems (such as a tumor that may be pressing on visual parts of the brain)
• Stroke
• People with diabetes and high blood pressure have a greater risk of developing blocked blood vessels in the optic nerve and retina. They may need visual field testing to monitor any effects of these conditions on their vision.
