How do doctors diagnose a loss of peripheral vision?

ANSWER

Your eye doctor will give you a visual field test to check for blank spots in your vision -- spots you might not even notice yet.

He’ll place a bowl-shaped device in front of your face. You’ll wear a patch over one eye so he can test each eye separately. While you look straight ahead, lights flash at different points around the bowl. You'll press a button when you see lights, without turning your head from side to side.

If you have an eye disease, your doctor might repeat this test every 6 to 12 months to measure changes in your vision. People who have a higher risk for glaucoma should also be tested regularly.
