Macular degeneration is a common eye condition—and one of the leading causes of vision loss in adults over 50. While it can sound intimidating, understanding macular degeneration and catching it early can make a big difference in protecting your eyesight.
At Byron Optometry, we believe eye care starts with education. Below, we break down macular degeneration in a clear, easy-to-understand way so you know what to watch for and when to book an eye exam.
What Is Macular Degeneration?
Macular degeneration, also known as age-related macular degeneration (AMD), affects the macula, the part of the retina responsible for sharp, central vision. This is the vision you use for reading, driving, using digital devices, and recognizing faces.
When the macula becomes damaged, central vision may become blurry, distorted, or dim, while side (peripheral) vision usually stays normal.
Types of Macular Degeneration
- Dry Macular Degeneration:
- The most common form of AMD
- Develops gradually over time
- Caused by thinning of the macula and small deposits called drusen
- Wet Macular Degeneration:
- Less common but more serious
- Can progress quickly
- Caused by abnormal blood vessels leaking fluid or blood under the retina
Early Signs and Symptoms of Macular Degeneration
- Blurred or hazy central vision
- Trouble reading or seeing fine details
- Straight lines appearing wavy
- A dark or empty spot in the center of vision
- Needing brighter light to read or work up close
What Causes Macular Degeneration?
- Aging (especially over age 50)
- Family history of macular degeneration
- Smoking
- High blood pressure or heart disease
- Excessive sun exposure without UV protection
- Poor diet low in antioxidants
How Is Macular Degeneration Diagnosed?
Comprehensive eye exams may include retinal imaging, OCT scans, dilated eye exams, and Amsler grid testing.
Macular Degeneration Treatment Options
- Specialized eye health vitamins (based on the AREDS2 formula) for certain stages of dry macular degeneration
- Lifestyle changes such as quitting smoking and improving nutrition
- Medical treatments for wet AMD through specialist referral
- Low-vision solutions to help with daily tasks
Important Note:
Eye health vitamins are not recommended for everyone and should only be taken after an eye exam and guidance from an eye care professional.
When Should You See an Optometrist?
If you’re over 50, have a family history of macular degeneration, or notice changes in your central vision, regular eye exams are essential.
