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.
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.
Occurs when retinal tissues thin and yellow deposits called drusen form beneath the retina
Progresses slowly over several years
Caused by abnormal blood vessel growth that leaks fluid or blood into the retina
Can lead to rapid and significant vision loss
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.
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.
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.
There is currently no cure for macular degeneration, but treatments can slow its progression and help protect your vision.
AREDS2 nutritional supplements
Diet rich in leafy greens & omega-3s
UV-protective eyewear
Lifestyle changes such as quitting smoking and increasing exercise
Anti-VEGF injections
Laser treatments
Photodynamic therapy
Early detection significantly increases treatment success.
While it cannot be fully prevented, you can lower your risk through a healthy diet, UV protection, avoiding smoking, and getting regular eye exams.
AMD affects central vision but usually does not cause total blindness. Peripheral vision often remains intact.
Adults 50+ should have a comprehensive eye exam every 1–2 years, or more often with risk factors or family history.
The AREDS2 formula—lutein, zeaxanthin, vitamins C & E, zinc, and copper—has been clinically proven to slow AMD progression.
Yes. Wet AMD progresses quickly and can cause sudden vision loss. Immediate treatment is crucial.
Many patients can drive in early stages, but advancing AMD may make driving unsafe. Your optometrist will determine what’s best for you.
This is a hallmark symptom of AMD. Schedule an eye exam as soon as possible.
Macular degeneration can be concerning, but early detection and proper care allow many patients to maintain useful vision for years. At North Coast Optometry, we offer advanced diagnostic tools and personalized treatment to protect your eyesight.
