Understanding AMD

What is AMD?

...and why you should take it seriously.

Age-related macular degeneration (AMD) is the world’s leading cause of severe and irreversible vision loss in people over 50. Studies show that AMD may be hereditary, and it’s recommended that anyone with a family history of AMD should have their eyes examined.

AMD affects the macula at the back of your eye, the part of the retina that controls your central vision, which lets you see fine detail like images directly in front of you or words on a page.

AMD is not painful and can occur in one or both eyes. How quickly the disease progresses varies from person to person, and from eye to eye. When the disease advances rapidly, it may lead to sudden and severe vision loss.

There are two forms of AMD - dry and wet.

Dry AMD

In dry AMD, yellow-colored fatty deposits called “drusen” build up in the cells of the macula. These can be detected by your eye doctor during a comprehensive eye exam. As the size and number of these deposits increase in the cells of the macula, so does your risk of developing wet AMD.

Dry AMD vs. Dry Eye

Dry AMD is not the same as “dry eye” and there is no connection between the two. Someone with dry eye doesn’t have enough quality tears to lubricate and nourish the eye. Dry eye affects the front, outside part of the eye whereas dry AMD affects the back, inside part of the eye.

Symptoms may include:
  • blurry vision up close (such as difficulty seeing sharp details)
  • blurry vision both up close and at a distance
  • no symptoms at all, or do not notice any of these changes in their vision over time

There is no treatment for dry AMD, and it can suddenly change to wet AMD without you even noticing. The chances of your dry AMD progressing to the more severe wet stage increases as the disease progresses over time.

Wet AMD

About 10-15% of people with dry AMD progress to a more advanced form called wet AMD. In wet AMD, abnormal blood vessels can suddenly leak fluid in the back of your eye without notice. It destroys the sharp, pinpoint vision needed to see clearly, which can cause permanent vision loss if left untreated. Wet AMD is also known as “neovascular” or “exudative” AMD.

When you have wet AMD your central vision becomes distorted. Symptoms include:

Blurry vision

Distortion of vision, straight lines look wavy

Dark spot (or spots) in the center of your vision

Wet AMD can severely impact your quality of life and limit your independence. It can make many of the activities you enjoy and rely on impossible; like driving, reading, watching television, and using a computer.

Catching the progression from dry to wet AMD as soon as possible is critical to prevent irreversible vision loss. It gives you the best chance of maintaining the vision you rely on every day and your independence. ForeseeHome can help.

Disease Progression

Severe vision loss can happen rapidly if wet AMD treatment is delayed. You may not notice any changes in your vision until significant vision loss has occurred.

Wet AMD Treatment

Unlike dry AMD, there are effective treatments for wet AMD.

Studies have shown that these treatments are most effective when initiated early, before any symptom are noticed and vision loss has occurred.

  • The disease will continue to progress until treatment begins
  • Rapid and severe vision loss can happen very quickly if treatment is delayed
  • Treatments can stop or slow the progression of wet AMD but cannot restore vision that has already been lost
  • You may not notice any changes in your vision until significant vision loss has occurred

ForeseeHome helps your doctor detect wet AMD earlier so treatment can begin earlier.
