What is Age-related Macular Degeneration (AMD)?

Age-related macular degeneration, or AMD, is a common eye condition. It mostly affects people over 50. AMD causes damage to the macula, which is the part of the eye that helps you see fine details. Because of this, people with AMD may have trouble reading, driving, or seeing faces clearly. Early detection is important, as AMD can lead to vision loss if not managed. According to the CDC, AMD is a leading cause of vision loss in older adults. However, with the right care, many people can slow its progress.

Common Symptoms of AMD

Recognizing macular degeneration symptoms early can help protect your vision. While symptoms may start slowly, they often get worse over time. For example, you may notice:

  • Blurry or fuzzy vision in the center of your sight
  • Dark or empty spots in the middle of your vision
  • Colors appearing less bright than before
  • Straight lines looking wavy or bent
  • Difficulty recognizing faces, even in good light

    • Not everyone will have all these signs. Still, if you notice any changes, it is important to see an eye doctor soon. Early action can help prevent further vision loss from AMD.

    Causes and Risk Factors

    There are several causes and risk factors for AMD. Although age is the biggest risk, other factors also play a role. For instance, genetics can increase your chances if a close family member has AMD. Smoking is another major risk factor. In addition, high blood pressure and obesity can raise your risk. Sun exposure and a poor diet may also contribute. Here are some common risk factors:

  • Being over 50 years old
  • Family history of AMD
  • Smoking cigarettes
  • High blood pressure
  • Obesity
  • Light-colored eyes
  • Excessive sun exposure

    • While you cannot change your age or family history, you can lower some risks by making healthy choices.

    How AMD is Diagnosed

    Diagnosing AMD usually starts with a visit to an eye care specialist. First, the doctor will ask about your symptoms and medical history. Next, they will perform a detailed eye exam. During the exam, your eyes may be dilated with drops. This helps the doctor see the back of your eye more clearly. Some common tests include:

  • Visual acuity test to check how well you see at different distances
  • Amsler grid test to spot changes in your central vision
  • Optical coherence tomography (OCT) to take detailed images of the retina
  • Fluorescein angiography to look at blood flow in the retina

    • With these tests, doctors can find AMD early and suggest the best AMD treatment options for you.

    Treatment Options for AMD

    Although there is no cure for AMD, several AMD treatment options can help slow its progress. The right treatment depends on the type and stage of AMD. For dry AMD, doctors may suggest:

  • Special vitamin and mineral supplements (AREDS2 formula)
  • Regular eye exams to monitor changes
  • Healthy lifestyle changes

    • For wet AMD, treatments may include:

  • Injections of anti-VEGF medicines to stop new blood vessel growth
  • Laser therapy to seal leaking blood vessels
  • Photodynamic therapy, which uses light and medicine together

    • Early treatment can help prevent severe vision loss from AMD. Your doctor will recommend the best plan for your needs.

    Lifestyle Tips and Prevention Strategies

    While you cannot stop aging, you can take steps to lower your risk of AMD. For example, healthy habits can help protect your eyes. Try these tips:

  • Eat a diet rich in leafy greens, fruits, and fish
  • Quit smoking and avoid secondhand smoke
  • Wear sunglasses to block harmful UV rays
  • Keep your blood pressure and cholesterol under control
  • Exercise regularly to maintain a healthy weight
  • Get regular eye exams, especially if you have risk factors

    • By following these steps, you can help in preventing vision loss from AMD and keep your eyes healthy for longer.
