Age-Related Macular Degeneration (AMD) Age-related macular degeneration or AMD is the leading cause of adult blindness in developed countries and affects nearly 1 in 8 adults over the age of 60. AMD is a chronic, progressive disease that attacks the macula, a part of the retina that allows us to see objects located straight ahead of us. The macula is responsible for your central vision, which allows you to do things like recognize faces, read, watch TV, and drive.
AMD Symptoms and Risk Factors The earliest symptom of AMD is impaired dark adaptation, which may cause difficulty seeing or driving at night. As the disease progresses, symptoms may include distortion of straight lines or dark and blurry central vision.
The primary risk factors for AMD include: • Age 50 or older • Family history of AMD • Caucasian (white) • Smoker or past smoker • Overweight • Heart disease, high blood pressure or high cholesterol
Age is the biggest risk factor. In fact, 1 in 8 adults over the age of 60 have age-related macular degeneration (AMD). If you are experiencing a symptom of AMD or have multiple risk factors, ask your doctor to test your eyes with the AdaptDx®
First in Canada!
People with age-related macular degeneration (AMD) often do not know they have the disease during its early stages. They may dismiss early warning signs, like trouble seeing or driving at night, as part of the normal aging process. Ignoring these symptoms only delays diagnosis, which can lead to more unnecessary vision loss. We are the first eye care provider to offer this new innovative test in Canada, the AdaptDx Dark Adaptometer, that helps us diagnose AMD at a very early stage and monitor disease progression. If you are experiencing problems seeing or driving at night or it is becoming increasing difficult to read in dim light, talk to us about scheduling an AdaptDx test.
AdaptDx® Dark Adaptometer – The AdaptDx [adapt-dee-ex] aids in the detection and management of AMD. It measures the time it takes for your vision to adjust to the dark. This is called dark adaptation. The simple test takes less than 10 minutes. You’ll look into the device in a darkened room and press a button every time you see a flashing light. If the AdaptDx test indicates signs of early AMD, you and your doctor have valuable time to develop a plan to delay disease progression.
What is RI? The RI™ stands for Rod Intercept™ and it is a measure of an eye’s dark adaptation function. Specifically, it is the number of minutes it takes your vision to adjust from light to darkness. When you take the AdaptDx test, the device calculates your RI number and provides your doctor with critical information to help determine your AMD status.
