Understanding Macular Degeneration: Central Vision Loss and Key FAQs

Wet age-related macular degeneration (wet AMD) is a serious, chronic eye disorder that can lead to significant vision impairment.

As we age, the macula—a small, central part of the retina responsible for sharp, detailed vision—can sustain damage. This area is crucial for seeing faces, reading text, and recognizing objects clearly, as it governs our central vision. Damage to the macula may occur in various ways.

The more prevalent form of this condition is dry AMD, which results from the buildup of deposits beneath the retina, causing the macula to thin over time.

In approximately 10% of cases, dry AMD can advance to wet AMD, characterized by the growth of abnormal blood vessels beneath the retina that leak fluid and cause scarring. This process is known as choroidal neovascularization (CNV).

Continue reading to find answers to frequently asked questions about wet AMD and its effects on vision, helping you to have informed discussions with your eye care specialist.

How does vision appear with macular degeneration?

Both dry and wet AMD primarily affect central vision due to macular damage or scarring.

This central vision loss means you may struggle to see fine details or experience difficulties adapting to changes in lighting conditions.

Your central vision allows you to focus directly on objects, read texts, and recognize faces clearly, whether near or far.

Importantly, peripheral (side) vision typically remains unaffected by AMD.

What is the risk of blindness from wet macular degeneration?

Blindness can result from AMD, especially in advanced stages and with the wet form of the disease.

While dry AMD tends to cause gradual vision decline, wet AMD is responsible for the majority of severe vision loss cases. Although it accounts for only 10% of AMD diagnoses, wet AMD causes 90% of AMD-related blindness.

How quickly does vision loss progress with macular degeneration?

AMD is the leading cause of vision loss among adults over 50. Wet AMD, though less common, leads to more rapid vision deterioration.

Vision changes from wet AMD can occur suddenly—sometimes within a single day—and without treatment, permanent vision loss may develop within weeks or months.

Therefore, early intervention is critical to prevent further vision decline.

Initial symptoms often include blurred or distorted central vision, but sometimes wet AMD is detected during routine eye exams before symptoms appear.

Does macular degeneration always result in blindness?

Not all AMD cases lead to blindness, but the risk is higher with wet AMD.

Regular eye check-ups and timely treatments—such as vitamin supplements, anti-VEGF injections, and surgical options—can slow or improve vision loss.

Wet AMD may be classified as active or inactive. Inactive status indicates successful treatment has halted leakage from abnormal blood vessels.

Vision may improve with treatment, but ongoing monitoring and therapy are necessary to maintain results.

How does macular degeneration impact reading?

AMD can distort text perception on both digital screens and printed materials, making reading more challenging.

While wet AMD doesn’t completely prevent reading, blind spots can slow reading speed and increase difficulty.

Using reading lamps, larger fonts, or magnifying tools can help. Consulting a low-vision specialist may also assist with daily activities.

Is it safe to drive with macular degeneration?

Macular degeneration can impair driving ability over time, especially with wet AMD.

Vision changes may reduce your ability to adjust to lighting variations, such as glare during sunset.

Blind spots can obstruct your view of vehicles, pedestrians, and cyclists, posing safety risks.

Consult your eye doctor for a professional evaluation of your driving capabilities.

Can vision be restored after macular degeneration?

Vision damage from AMD cannot be reversed, but early diagnosis and treatment can reduce the risk of severe vision loss.

Treatment options include lifestyle modifications, medications, and sometimes surgery. Research continues to explore new therapies.

Summary

Macular degeneration is a progressive condition, with wet AMD causing more rapid vision issues than dry AMD. Early detection and treatment are vital for better outcomes.

Regular eye exams and adherence to treatment plans are essential. If you experience sudden vision changes like blurriness, distortion, or blind spots, seek immediate medical advice. Using an Amsler Grid at home can help monitor your vision and alert you to changes promptly.
