What Is Macular Degeneration? Understanding the Leading Cause of Vision Loss in Seniors

Macular degeneration is one of the most common causes of vision loss in older adults - and it often develops quietly. You might first notice small changes like needing brighter light to read, struggling to recognize faces across the room, or seeing mild distortion when looking at straight lines. Because these early signs can be easy to dismiss as “normal aging,” many people don’t realize the macula is being affected until the condition has progressed.

What Is Macular Degeneration?

Macular degeneration, often called age-related macular degeneration (AMD), is a condition that affects the macula - the small, central portion of the retina responsible for sharp, detailed vision. The macula helps you do the tasks that require clarity, such as reading, driving, recognizing faces, sewing, or using a phone.

AMD typically causes gradual loss of central vision, while peripheral vision often remains intact. It does not usually lead to complete blindness, but it can significantly affect independence and quality of life.

Types of Macular Degeneration

There are two primary types of AMD:

• Dry AMD (Most Common): Dry AMD develops when the macula gradually thins over time and tiny deposits called drusen build up under the retina. Vision changes tend to be slow and mild at first, then may progress.

• Wet AMD (Less Common, More Severe): Wet AMD occurs when abnormal blood vessels grow beneath the retina and leak fluid or blood. This type can cause rapid and significant vision loss without prompt treatment. The good news is that modern treatment options can often slow the disease and help preserve vision.

Common Symptoms to Watch For

Macular degeneration can begin without obvious symptoms, especially in the earliest stages. Over time, you may notice:

• Blurry or fuzzy central vision

• Trouble reading small print even with glasses

• Straight lines appearing wavy or distorted

• Difficulty recognizing faces

• A dark, blank, or “missing” spot in the center of vision

• Needing brighter light for close-up tasks

Because symptoms can be subtle at first, many people don’t realize anything is wrong until the condition has progressed. Routine eye exams can catch early signs before major changes occur.

Who Is at Risk?

Age is the strongest risk factor - AMD becomes more common after age 50. Other risk factors include:

• Family history of macular degeneration

• Smoking (one of the most significant modifiable risks)

• High blood pressure or cardiovascular disease

• High cholesterol

• Excessive sun/UV exposure without protection

• Poor diet low in leafy greens and antioxidants

• Obesity or sedentary lifestyle

Even if you feel your vision is “fine,” risk factors are a strong reason to stay consistent with comprehensive eye exams.

How Routine Eye Exams Help Protect Your Vision

Macular degeneration often begins before you notice changes. During a medical eye exam, our eye doctor can evaluate the retina and macula for early signs of AMD, including drusen and subtle pigment changes.

Routine exams can help by:

• Detecting AMD early, often before symptoms start

• Monitoring progression over time

• Identifying wet AMD quickly - when treatment is most effective

• Recommending lifestyle changes to support eye health

• Discussing supplements (such as AREDS2 formulas) when appropriate

• Coordinating timely treatment if needed

If you’re over 50, have a family history, or have other health conditions like hypertension, regular exams become even more important.
