Age-Related Macular Degeneration (AMD) Testing

Open your eyes to better AMD management and early detection with this non-invasive eye exam that is easy to perform and you can get your test results in minutes right here at the Corinth Eye Clinic.

AMD is one of the most common age-related diseases of the eye. AMD is common, the risk of getting AMD increases from 2% for those ages 50-59, to nearly 30% for those over the age of 75. AMD is the leading cause of irreversible vision loss in people over the age of 65.

How AMD Destroys Your Sight

AMD progressively destroys highly sensitive tissue in the macula – the area at the back of the eye where light is focused and nerve signals tell your brain what you are seeing. This is known as central vision; a sharp focus in the center of your visual range.

Early detection and treatment of macular degeneration may help reduce the extent of vision loss. AMD is often referred to as dry AMD and wet AMD. While both affect your central vision, it is important to know the differences so we can take appropriate action.

The Two Types of AMD

DRY AMD

Most people with AMD have this form of the disease. Usually, dry AMD does not cause severe vision loss. In some people, however, central vision loss can occur slowly, with a slight blurring that may prompt you to add light for reading and other tasks. Because AMD causes no pain and the visual symptoms are generally mild, many people consider a slow loss of central vision to be just a normal part of aging. But there is nothing normal about AMD – particularly if it progresses to the more sever form: wet AMD.

WET AMD

About 20% of people with dry AMD will progress to the wet form of the disease. In wet AMD, tiny blood vessels underneath the retina grow abnormally. Often, these blood vessels cause blood cause blood and fluid to lead under the macula. The resulting damage can be devastating, leading to rapid, severe and permanent central vision loss unless it is detected and treated early.

A Simple Test Can Help Save Your Sight – FORESEE PHP

The Foresee PHP provides a simple, quick and noninvasive way to detect abnormalities in the macula that may suggest the presence of the sever form of AMD.

Regular monitoring with Foresee PHP, after initial detection, can let you and your doctor know if your AMD is progressing to the severe, wet form of the disease before you experience visual symptoms, at the stage of the disease when treatment is most effective.

What to Expect

Foresee PHP analysis can be completed at Corinth Eye clinic in our testing room free from patient distraction with dimmed lighting. Your non-test eye will be occluded. You will be seated comfortably with your chin in the chin rest so you can view the screen. You will be viewing a dark background with white dotted lines flashing on the screen repeatedly, one at a time, in different locations on the screen. In your hand, you will hold a stylus which you will touch to the screen after each stimulus flashes and return your hand to a small pad in front of the chin rest called the patient home base. Therefore, you should rest your elbow comfortably on the table allowing you to touch the screen and the home base. You will be asked to respond to distortion you see on the dotted line stimuli. It will take approximately five minutes for each eye. Your results will be saved for the doctor to analyze and interpret.

With AMD, There is No Time to Lose
