Macular degeneration—more formally known as Age-Related Macular Degeneration (AMD)—is one of the leading causes of vision loss in adults over 50. While AMD doesn’t typically cause complete blindness, it affects central vision and can make daily tasks like reading, recognizing faces, and driving increasingly difficult.
At North Coast Optometry, we believe early detection is essential for protecting long-term vision. In this guide, we break down everything you need to know about macular degeneration—from risks and symptoms to prevention strategies and treatment options.
What Is Macular Degeneration?
The macula is a small but crucial part of the retina responsible for sharp, central vision. When it deteriorates, vision becomes blurry, distorted, or darkened. AMD is progressive, meaning it worsens over time.
The Two Main Types of AMD
1. Dry AMD (Most Common)
- Occurs when retinal tissues thin and yellow deposits called drusen form beneath the retina
- Progresses slowly over several years
2. Wet AMD (Less Common but More Severe)
- Caused by abnormal blood vessel growth that leaks fluid or blood into the retina
- Can lead to rapid and significant vision loss
Common Symptoms of Macular Degeneration
While AMD may begin without noticeable symptoms, patients often report:
- Blurred or fuzzy central vision
- Straight lines appearing wavy or distorted
- Difficulty reading or recognizing faces
- Dark or empty spots in central vision
- Colors appearing faded or dull
- Needing brighter light for close-up tasks
If you notice any of these symptoms, schedule an eye exam immediately.
Risk Factors for Macular Degeneration
You may be at higher risk if you have:
- Age 50+
- Genetics or family history of AMD
- Smoking
- High blood pressure
- High cholesterol
- Poor diet (low in leafy greens and antioxidants)
- UV exposure
- Light-colored eyes
At North Coast Optometry, we use advanced retinal imaging to detect early changes—often before symptoms appear.
How Is Macular Degeneration Diagnosed?
A comprehensive eye exam may include:
- Dilated retinal exam
- Optical Coherence Tomography (OCT)
- Amsler grid testing
- Macular pigment analysis
- Retinal photography
These tools help monitor your macula and catch early signs of AMD.
Treatment Options for AMD
There is currently no cure for macular degeneration, but treatments can slow its progression and help protect your vision.
Dry AMD Treatments
- AREDS2 nutritional supplements
- Diet rich in leafy greens & omega-3s
- UV-protective eyewear
- Lifestyle changes such as quitting smoking and increasing exercise
Wet AMD Treatments
- Anti-VEGF injections
- Laser treatments
- Photodynamic therapy
Early detection significantly increases treatment success.
Macular Degeneration Q&A
Can macular degeneration be prevented?
While it cannot be fully prevented, you can lower your risk through a healthy diet, UV protection, avoiding smoking, and getting regular eye exams.
Does macular degeneration cause blindness?
AMD affects central vision but usually does not cause total blindness. Peripheral vision often remains intact.
How often should I get screened?
Adults 50+ should have a comprehensive eye exam every 1–2 years, or more often with risk factors or family history.
What vitamins help macular health?
The AREDS2 formula—lutein, zeaxanthin, vitamins C & E, zinc, and copper—has been clinically proven to slow AMD progression.
Is wet AMD more dangerous than dry AMD?
Yes. Wet AMD progresses quickly and can cause sudden vision loss. Immediate treatment is crucial.
Can I still drive with macular degeneration?
Many patients can drive in early stages, but advancing AMD may make driving unsafe. Your optometrist will determine what’s best for you.
What should I do if straight lines look wavy?
This is a hallmark symptom of AMD. Schedule an eye exam as soon as possible.
