What Is Macular Degeneration? Understanding Symptoms, Causes, and Treatment Options

Macular degeneration is a progressive eye condition and one of the leading causes of vision loss in adults over the age of 50. It affects the macula, the central portion of the retina responsible for clear, central vision. This part of the eye is essential for reading, driving, recognizing faces, and other tasks that require detailed sight. As the macula deteriorates, central vision becomes blurry or distorted, while peripheral vision is usually unaffected.

There are two main forms of macular degeneration: dry and wet. Each type has different causes and treatment approaches.

Types of Macular Degeneration

Dry macular degeneration is the more common form, accounting for nearly 90 percent of cases. It develops gradually as the macula thins over time, often accompanied by the buildup of small yellow deposits called drusen under the retina. Symptoms tend to develop slowly and may go unnoticed in the early stages.

Wet macular degeneration is less common but more serious. It occurs when abnormal blood vessels grow under the retina and leak fluid or blood, which can cause rapid and significant central vision loss. This type requires prompt treatment to help preserve remaining vision.

Common Symptoms

Symptoms may vary depending on the stage and type of the condition, but some of the most common include:

• Blurred or distorted central vision
• Difficulty reading or seeing fine details
• Dark or empty spots in the center of your vision
• Colors appearing less vibrant or bright
• Straight lines appearing wavy or bent

Since the disease can progress slowly, especially in its dry form, regular eye exams are essential for early detection and management.

Risk Factors

Several factors may increase the likelihood of developing this condition:

• Being over the age of 60
• Family history of the disease
• Smoking
• High blood pressure or cardiovascular conditions
• Poor diet low in antioxidants
• Prolonged exposure to UV light
• Obesity

While age and genetics can’t be controlled, adopting a healthier lifestyle can help lower your overall risk.

How It’s Diagnosed

At Advanced Eye Care Center, we use advanced diagnostic tools to detect and monitor macular degeneration. These may include a dilated eye exam, Amsler grid testing, optical coherence tomography (OCT), and in some cases, fluorescein angiography to examine blood vessel behavior.

Treatment Options

There is no cure for macular degeneration, but several treatments can help slow its progression and improve quality of life.

For dry forms, management typically includes:

• High-dose vitamin supplements (AREDS2 formula)
• Eating a nutrient-rich diet with leafy greens and omega-3s
• Managing blood pressure and quitting smoking
• Routine monitoring with eye exams

For wet forms, treatment may involve:

• Injections of anti-VEGF medications to reduce fluid buildup and stop abnormal vessel growth
• Photodynamic therapy using light-sensitive drugs and laser treatment
• Laser therapy to seal leaking blood vessels (less commonly used now)

Early diagnosis and timely treatment are crucial for preserving vision, especially with the wet form of the disease.

Managing Life with Macular Degeneration

Living with vision loss can be challenging, but many people continue to lead active lives with proper support and tools. Low vision aids like magnifiers, large-print materials, and digital devices can help. Vision rehabilitation programs and support groups also offer valuable resources for adjustment and daily living.

Our team at Advanced Eye Care Center is dedicated to helping patients manage this condition with compassionate, customized care. From diagnosis to treatment, we’re here to guide you every step of the way.
