Macular Degeneration

Age-related macular degeneration (AMD) is a leading cause of vision loss in older adults that destroys sharp, central vision required for daily tasks.

Macular degeneration, or age-related macular degeneration (AMD), is a leading cause of vision loss in Americans 60 and older. It is a disease that destroys your sharp, central vision. You need central vision to see objects clearly and to do tasks such as reading and driving.

AMD affects the macula, the part of the eye that allows you to see fine detail. It does not hurt, but it causes cells in the macula to die. There are two types:

  • Wet AMD: Happens when abnormal blood vessels grow under the macula. These new blood vessels often leak blood and fluid, damaging the macula quickly. Blurred vision is a common early symptom.
  • Dry AMD: Happens when the light-sensitive cells in the macula slowly break down. You gradually lose your central vision. A common early symptom is that straight lines appear crooked.

Regular comprehensive eye exams can detect macular degeneration before the disease causes vision loss. Treatment can slow vision loss, but it does not restore vision.

Frequently Asked Questions

The most common treatment is intravitreal injections of anti‑VEGF medications (e.g., ranibizumab, aflibercept, or bevacizumab). These injections inhibit abnormal blood vessel growth and can stabilize or improve vision in many patients. Treatment frequency varies but typically starts every 4–6 weeks and may taper to monthly or bi‑monthly intervals depending on response. Photodynamic therapy and laser photocoagulation are alternative options, though less commonly used today.===
Wet AMD often starts with sudden blurred vision, a distortion of straight lines, or a dark spot in the center of vision. If you notice any of these changes, schedule an appointment promptly, as early treatment can preserve remaining vision.
Most clinicians recommend a comprehensive eye exam at least once a year for early dry AMD. If your condition shows signs of progression—such as increasing central vision loss—your eye doctor may suggest exams every six months to monitor changes closely.
Yes. A diet rich in leafy greens, fish high in omega‑3 fatty acids, and foods high in antioxidants (vitamins C, E, lutein, zeaxanthin) has been linked to slower AMD progression. Quitting smoking and maintaining a healthy weight also help reduce risk.
