Age-related macular degeneration (AMD) is one of the leading causes of vision loss in adults over 50. Fortunately, early diagnosis can make a world of difference. At Silicon Valley Eye Physicians in Sunnyvale, we’re here to help protect your sight from eye disease with regular eye exams, early detection, and personalized care.
What Is Macular Degeneration?
Macular degeneration, or AMD, is a progressive eye disease that affects the macula—the small central portion of the retina responsible for sharp, straight-ahead vision. When the macula deteriorates, your ability to see fine detail starts to decline, even though your peripheral vision may remain unaffected.
There are two primary types of macular degeneration:
- Dry AMD (Atrophic): This is the most common form and typically develops gradually. It's characterized by thinning of the macula and accumulation of small yellow deposits called drusen.
- Wet AMD (Neovascular): Though less common, this type progresses faster and is more likely to cause severe central vision loss. It involves the growth of abnormal blood vessels that leak fluid or blood under the retina.
Many people in the early stages of AMD don’t experience symptoms. That’s why this condition often goes undetected without a comprehensive eye exam—including dilation and advanced retinal imaging.
How AMD Impacts Your Daily Life
AMD can make it difficult to do the things you love—especially when it comes to detailed or close-up tasks. Left unmanaged, it can affect your ability to:
- Read books, menus, or your phone screen
- Recognize familiar faces
- Watch television clearly
- Drive safely, especially at night
- Work on hobbies like knitting, painting, or using tools
People with advanced AMD often describe seeing dark or blurry spots in the center of their vision, or experiencing distortions like straight lines appearing wavy. Over time, this loss of clarity can reduce independence and quality of life.
That’s why February’s Macular Degeneration Awareness Month serves as a vital reminder: early action leads to better outcomes.
What Causes Macular Degeneration?
The exact cause of AMD isn’t fully understood, but several factors are known to contribute:
- Age: Risk rises significantly after age 50
- Genetics: Family history plays a role
- Smoking: Doubles your risk of AMD
- Obesity and high blood pressure: Can contribute to disease progression
- Poor diet: Lacking antioxidants and omega-3 fatty acids
- Sun exposure: UV light may accelerate macular damage
Fortunately, there are steps you can take to lower your risk and protect your macula over time.
Prevention Tips: Protecting Your Vision Starts Now
While you can’t change your age or genetics, many lifestyle changes can help reduce your risk of AMD or slow its progression:
- Eat a macula-friendly diet: Dark leafy greens (like spinach and kale), brightly colored fruits and vegetables, nuts, and fish high in omega-3s all support eye health.
- Wear sunglasses: UV protection matters—especially in sunny climates like California.
- Stop smoking: This is one of the single biggest changes you can make to protect your eyes.
- Control blood pressure and cholesterol: Both are linked to eye health.
- Exercise regularly: Keeps blood vessels healthy, including those in your eyes.
- Take vision-specific supplements if recommended: Some patients benefit from AREDS2-based vitamins.
At Silicon Valley Eye Physicians, we’re happy to offer personalized guidance based on your specific risk factors during your annual eye exam.
How We Detect and Track AMD
Our experienced optometrists use advanced retinal technology to detect AMD in its earliest stages—even before you notice vision changes.
Here are a few tools we may use during your visit:
- Optical Coherence Tomography (OCT): Provides high-resolution cross-sectional images of the retina.
- Fundus Photography: Captures detailed pictures of the back of your eye, allowing us to track changes over time.
- Amsler Grid Test: Helps identify subtle distortions in central vision.
- Visual Acuity Testing: Measures your ability to see fine detail at various distances.
By comparing results over time, we can monitor progression and adjust your care plan accordingly. If needed, we may refer patients with wet AMD to a retinal specialist for further evaluation.
Can Macular Degeneration Be Treated?
There is currently no cure for AMD—but that doesn’t mean nothing can be done.
Dry AMD: While we can’t reverse damage, lifestyle changes and nutritional support can slow progression.
Wet AMD: There are highly effective treatments, such as anti-VEGF injections, that can stop the growth of abnormal blood vessels and preserve vision when caught early.
Early diagnosis makes a significant difference in outcomes, especially with wet AMD. That’s why ongoing monitoring is so critical.
