Over 11 million people in the United States are affected by some form of AMD, with those over the age of 50 being the most vulnerable. According to the National Eye Institute, that number will likely double in the next 30 years.

All About Macular Degeneration

Those diagnosed with age-related macular degeneration (AMD) are likely unable to identify the moment when their vision started to change. Their eyesight declines gradually, so it’s not uncommon for them to keep running errands, watching television, or continue working on various projects.

But suddenly, colors become darker. Seeing directly ahead becomes a struggle, and both vision and independence start to erode. And when the diagnosis finally becomes real, it can be a devastating and depressing blow that can be frustrating and kill even the most resilient resolve.

The struggle to remain independent is why so many stories of dealing with AMD remain untold. The condition flies under the radar of those most prone to it, but with a diagnosis of AMD comes the risk of losing your driver’s license, a diminished social life, and, in later stages of the disease, the potential inability to recognize the faces of loved ones.

Over 11 million people in the United States are affected by some form of AMD, with those over the age of 50 being the most vulnerable. According to the National Eye Institute, that number will likely double in the next 30 years. Exciting new research has given AMD sufferers some hope in the battle with this degenerative disease. Unfortunately, however, there is still no cure.

Understanding how AMD works and when it starts are keys to slowing or stopping its progression. We’ll take a closer look at the symptoms and causes of AMD, some treatments on the horizon and how those diagnosed with it can effectively manage their symptoms.

What are the Causes of AMD?

In finding a cure for AMD, the field of genetics looks particularly promising. According to WebMD, researchers have discovered at least 20 genes connected to AMD. But it’s also our family histories that put us at risk for developing the condition. If a member of your family suffers from AMD, your chances of getting it goes up.

Family History, Gender, Race and Lifestyle Habits

Gender and race are other factors that increase the risk of AMD. Nearly two-thirds of those living with the condition are women, and a third of those afflicted are white. Almost a third of those over the age of 75 have AMD and your chances of getting it goes up after you turn 50. Other factors that increase your AMD risk include smoking, obesity, high blood pressure and heart disease.

What is the Difference Between Dry and Wet Macular Degeneration?

Dry Macular Degeneration

There are two stages of AMD. The first kind is dry macular degeneration. The macula, the part of our retina that provides clear vision to our direct line of sight, begins to thin out and deteriorate as we grow older. Those who suffer from dry macular degeneration may not lose their vision entirely. The disorder can develop in one or both eyes and worsen over time.

Wet Macular Degeneration

Dry macular degeneration can progress to the wet stage, occurring when new blood vessels grow underneath and into the macula. These irregular developments may leak fluid or blood, which can block light from reaching the retina, and harms the structure of the retina. Additionally, it’s caused when fluid builds up between the retina and a thin cell layer called the retinal pigment epithelium, causing distorted vision.

The Benefits of Being Peer-Reviewed

It can be difficult for people to know when the symptoms of AMD begin. Sometimes, one’s vision declines slowly, with a slight change in color or a dark spot in the center of your field of view. Other times, straight lines can appear wavy. Regular visits to your eye care professional can help detect AMD early. Some other signs of AMD to look out for are:

  • A blurred or blind spot in the center of your vision
  • Difficulty adjusting your eyes in low-lit areas
  • Printed words that are fuzzy and difficult to read
  • Difficulty visually recognizing faces
  • Reduced ability to distinguish objects from their background

Can the Symptoms of Macular Degeneration be Managed or Treated?

For those who are s­­truggling with AMD, there is some hope. While there currently isn’t a cure, there are treatments that can help regulate its symptoms. The most important thing you can do is to see an optometrist regularly and get tested for AMD. Th­­­ere are also laser therapies or invasive drugs injected into the eye, both of which can halt the growth of abnormal blood vessels that can leak fluid into the retina. Less intrusive treatments include quitting smoking and a balanced diet that includes vegetables.

Supplements are a non-invasive, natural treatment shown to help AMD patients by replenishing macular pigment levels in the eye. With continuous supplementation, patients can reduce the risk of progression dramatically and improve their visual performance. MacuHealth, which includes all three carotenoids that make up the macular pigment, has been scientifically proven to protect the eye from damage, rebuild macular pigment and delay the symptoms of AMD.
