Age-Related Macular Degeneration (AMD)
Age-related macular degeneration or AMD is a chronic, progressive disease that causes a part of your retina, called the macula, to slowly deteriorate as you get older. The macula is responsible for your central vision, which allows you to do things like recognize faces, read, watch TV, and drive. As the leading cause of vision loss and blindness in adults, AMD is more common than glaucoma and dry eye disease combined.
GET THE FACTS
As a progressive disease, AMD is hardly noticed by most patients in the earliest stages. However, one of the earliest symptoms of AMD is impaired dark adaptation, known as night vision and often presenting as complaints of trouble driving or seeing at night. As the disease progresses, symptoms may include distortion of straight lines or dark and blurry central vision. There are several risk factors for AMD, including:
- Age 50 or older
- Family history of AMD
- Caucasian (white)
- Smoker or past smoker
- Being overweight
- Heart disease, high blood pressure or high cholesterol
If you are experiencing a symptom of AMD or have multiple risk factors, you should be tested with the AdaptDx®.
1. It is projected that the overall prevalence of the AMD will be 196 million in 2020 and 288 million in 20401.
2. As many as 11 million people in the U.S. have some form of AMD; this number is expected to double by 20501.
3. Up to 78% of AMD patients have substantial, irreversible vision loss at first treatment, including 37% who are legally blind in at least one eye2,3.
4. Currently, there is no cure for AMD but progression of the disease can be slowed or halted with lifestyle modifications, protective eyewear, and nutritional supplements. Timely diagnosis is therefore key.
5. Wet AMD (choroidal neovascularization) may be treated with injections, which can slow or halt disease progression and vision loss, but not reverse it.
