Age-related macular degeneration (AMD) is a leading cause of vision loss in adults over 50. If you or a loved one has been diagnosed with macular degeneration, or if you’re concerned about your risk, understanding the condition and your options for care is an important first step.
At Overlake EyeCare, we provide comprehensive macular degeneration screening and management at our Bellevue and Kirkland locations. This guide explains what AMD is, how it affects your vision, and what you can do to protect your eyesight.
Key Takeaways
- Age-related macular degeneration (AMD) affects the central part of your vision and is most common in adults over 50.
- There are two types: dry AMD (more common, slower progression) and wet AMD (less common, more serious).
- Early detection through regular eye exams is critical, as treatment is most effective when AMD is caught early.
- While there’s no cure, lifestyle changes and medical treatments can slow progression and preserve vision.
- Overlake EyeCare offers AMD screening and ongoing management at both Bellevue and Kirkland locations.
1. What Is Macular Degeneration?
The macula is the central part of the retina, the light-sensitive tissue at the back of your eye. It’s responsible for your sharp, detailed central vision, which you use for reading, driving, recognizing faces, and seeing fine details.
When the macula deteriorates, you lose that central vision while peripheral (side) vision usually remains intact. This means you might be able to see that someone is standing in front of you, but not clearly see their face. AMD doesn’t cause complete blindness, but it can significantly impact your ability to perform everyday tasks.
Risk Factors for AMD:
- Age (most common in those over 50, risk increases with age)
- Family history of macular degeneration
- Smoking (significantly increases risk)
- Caucasian ethnicity
- Obesity and cardiovascular disease
- Prolonged sun exposure without eye protection
2. Dry AMD vs. Wet AMD: Understanding the Types
There are two forms of age-related macular degeneration, and understanding which type you have is important for determining the right approach to care.
Dry AMD (Atrophic)
Dry AMD is the most common form, accounting for about 80-90% of cases. It occurs when the light-sensitive cells in the macula gradually break down. Yellow deposits called drusen accumulate under the retina. Dry AMD typically progresses slowly over years, and many people with early dry AMD experience little to no vision loss. However, dry AMD can progress to the more serious wet form.
Wet AMD (Neovascular)
Wet AMD is less common but more serious. It occurs when abnormal blood vessels grow beneath the retina and leak blood or fluid, causing rapid damage to the macula. Wet AMD can cause sudden, significant vision loss and requires prompt treatment. The good news is that treatments are available that can slow or stop the progression of wet AMD if caught early.
Comparing Dry and Wet AMD
| Dry AMD | Wet AMD | |
|---|---|---|
| Prevalence | 80-90% of AMD cases | 10-20% of AMD cases |
| Cause | Gradual breakdown of macular cells; drusen deposits | Abnormal blood vessel growth and leakage |
| Progression | Usually slow (years) | Can be rapid (weeks to months) |
| Vision Loss | Gradual; may be minimal in early stages | Can be sudden and significant |
| Treatment | Lifestyle changes, AREDS supplements, monitoring | Anti-VEGF injections, lifestyle changes |
3. Symptoms and Warning Signs
In its early stages, macular degeneration often has no noticeable symptoms, which is why regular eye exams are so important. As the condition progresses, you may notice:
- Blurry or fuzzy central vision
- Straight lines appearing wavy or distorted (a key warning sign)
- A dark or empty area in the center of your vision
- Difficulty recognizing faces
- Need for brighter light when reading
- Colors appearing less vivid
- Difficulty adapting to low light levels
If you notice sudden changes in your vision, especially if straight lines appear wavy, contact your eye doctor right away. This could indicate wet AMD, which requires prompt treatment.
4. How Macular Degeneration Is Diagnosed
Macular degeneration is typically detected during a comprehensive dilated eye exam. Your eye doctor will use several methods to evaluate the health of your macula:
Dilated Eye Exam: Eye drops widen your pupils so your doctor can examine the retina and macula for signs of AMD, including drusen deposits.
Amsler Grid Test: A simple test using a grid of straight lines. If the lines appear wavy or distorted, it may indicate macular damage.
OCT (Optical Coherence Tomography): Advanced imaging that creates detailed cross-section images of the retina, allowing your doctor to see the layers of the macula and detect fluid or abnormal blood vessels.
Fluorescein Angiography: If wet AMD is suspected, a special dye may be injected to highlight blood vessels in the retina and identify any that are leaking.
5. Treatment and Management Options
While there’s currently no cure for macular degeneration, treatments and lifestyle changes can help slow progression and preserve your remaining vision.
For Dry AMD:
- Regular monitoring to track progression
- AREDS2 vitamin supplements (specific formulation shown to slow progression in intermediate to advanced dry AMD)
- Lifestyle modifications (quit smoking, healthy diet, exercise)
- Low vision aids and rehabilitation services if vision loss occurs
For Wet AMD:
- Anti-VEGF injections: Medications injected into the eye that block the growth of abnormal blood vessels.
- Photodynamic therapy: A combination of a light-activated drug and laser treatment to destroy abnormal blood vessels.
- Laser surgery: In some cases, laser treatment can seal leaking blood vessels.
6. Protecting Your Vision: Prevention and Lifestyle
- Don’t smoke: Smoking significantly increases AMD risk.
- Eat a healthy diet: A diet rich in leafy greens, fish high in omega-3 fatty acids, and colorful fruits and vegetables supports eye health.
- Exercise regularly: Physical activity improves cardiovascular health, which is linked to eye health.
- Protect your eyes from UV light: Wear sunglasses that block UV rays when outdoors.
- Get regular eye exams: Adults over 50 should have comprehensive eye exams at least every 1-2 years.
- Monitor your vision: Use an Amsler grid at home to check for changes between appointments.

Frequently Asked Questions
What is macular degeneration?
Macular degeneration is an age-related eye condition that affects the macula, the central part of the retina responsible for sharp, detailed vision. It causes gradual loss of central vision while peripheral vision typically remains intact. It’s most common in adults over 50.
Where can I get macular degeneration treatment near Kirkland?
Overlake EyeCare provides macular degeneration screening and management at our Kirkland and Bellevue locations. We offer advanced diagnostic imaging and work with retinal specialists for patients who need advanced treatment like anti-VEGF injections.
Can macular degeneration be cured?
There is currently no cure for macular degeneration. However, treatments for wet AMD can slow or stop vision loss, and lifestyle changes and supplements may slow progression of dry AMD. Early detection and ongoing monitoring are essential for preserving vision.
How often should I get checked for macular degeneration?
Adults over 50 should have comprehensive dilated eye exams every 1-2 years. If you have risk factors for AMD or have been diagnosed with early AMD, more frequent monitoring may be recommended.
What are the early signs of macular degeneration?
Early AMD often has no symptoms. As it progresses, you may notice blurry central vision, straight lines appearing wavy, difficulty reading or recognizing faces, or needing more light. Sudden vision changes should be evaluated immediately.
Does insurance cover macular degeneration screening?
Yes, macular degeneration screening is typically covered as part of a medical eye exam when there’s a medical indication. Medicare and most medical insurance plans cover these exams. Our team can help you understand your specific coverage.
