Visual Fields by Automated Perimetry
A painless test of side vision One-to-One EyeCare provides computerized peripheral vision testing called “automated perimetry” using a machine called the Humphrey Automated Field Analyzer. We use this painless technology primarily to monitor for any loss of side vision in glaucoma patients that would indicate a need for additional treatment.

Earlier detection allows earlier treatment
Glaucoma is a condition in which decreased blood flow to the optic nerve, the large bundle of nerve fibers which carry vision signals from the eye to the brain. While the most common form of glaucoma has no symptoms, it can gradually cause a loss of side vision or “peripheral” vision. If not detected early and treated properly, the side vision loss can progress to total blindness. When caught early and treated, glaucoma need not cause any noticeable vision loss. Visual field testing helps detect glaucoma before significant vision damage occurs and can help screen for any worsening patients already receiving treatment for glaucoma.

Important vision information at the touch of a button
Automated perimetry is a painless in-office test that takes just a few minutes. You look at a projection screen on which a computer presents small lights of various intensities in different areas of your side vision. When you see the light being presented, you press a button. When you don’t press the button, the computer records the fact that you did not see the light. At the completion of the test, the computer analyzes the data and prints out a report for our interpretation.

Automated perimetry has many applications
Computerized visual field testing has important applications beyond glaucoma. It can be used to detect loss of side vision from neurological conditions such as stroke, brain tumors, multiple sclerosis and many others. It is even used to help document the need for surgery to lift droopy eyelids. Droopy eyelids can block the upper field of vision. This is detected by testing the upper field of vision with the lids in their normal position and then re-testing with the lids taped up to see if the range of upper vision improves.

At One-to-One EyeCare, visual field testing by automated perimetry is another
example of the way we use advanced technology to meet your eye care needs.
