7 Key Symptoms of Wet Macular Degeneration You Should Know

Wet macular degeneration, also known as wet AMD (age-related macular degeneration), is a serious eye condition that affects the macula—the central part of the retina responsible for sharp, detailed vision. Unlike its more common counterpart, dry AMD, wet macular degeneration progresses rapidly and can lead to significant vision loss if left untreated. This condition occurs when abnormal blood vessels grow beneath the retina and leak fluid or blood, causing damage to the macula.

Understanding the symptoms of wet AMD is crucial for early detection and intervention. While wet macular degeneration accounts for only about 10-15% of all AMD cases, it is responsible for approximately 90% of severe vision loss related to the disease. Recognizing these warning signs can help you seek prompt medical attention and potentially preserve your vision.

1. Distorted Vision (Metamorphopsia)

One of the hallmark symptoms of wet macular degeneration is metamorphopsia, or visual distortion. This occurs when straight lines appear wavy, bent, or crooked. For example, when looking at a door frame, window blinds, or the edges of buildings, these normally straight lines may seem to ripple or curve.

This distortion happens because fluid accumulation beneath the retina causes the macula to swell or lift, disrupting the normal arrangement of light-sensing cells. The Amsler grid test, a simple diagnostic tool consisting of a grid of straight lines, is commonly used to detect this symptom. If you notice that the lines on the grid appear wavy or distorted, especially when covering one eye at a time, this could indicate wet AMD.

What makes this symptom significant: Metamorphopsia often appears suddenly and may be one of the earliest noticeable signs of wet macular degeneration. Many patients report that this distortion begins in one eye before affecting the other.

2. Blurred or Decreased Central Vision

Blurred central vision is another prominent symptom of wet AMD. You may notice that objects directly in your line of sight appear fuzzy or unclear, while your peripheral (side) vision remains intact. This can make activities requiring detailed vision—such as reading, driving, or recognizing faces—increasingly difficult.

The blurriness results from damage to the macula caused by leaking blood vessels. As fluid accumulates and disrupts the normal structure of the retina, your ability to see fine details deteriorates. Unlike the gradual vision changes that typically occur with dry AMD, the blurring associated with wet macular degeneration can develop rapidly, sometimes over days or weeks.

You might experience:

• Difficulty reading small print, even with reading glasses
• Trouble seeing details in familiar faces
• Increased need for brighter lighting when performing close-up tasks
• Words appearing blurry or jumbled when reading

3. Central Dark or Blank Spot (Scotoma)

A dark, blank, or blurry spot in the center of your visual field, known as a central scotoma, is a characteristic symptom of wet macular degeneration. This spot may start small and gradually expand as the condition progresses. Unlike a floater that moves with your eye, a scotoma remains fixed in your central vision.

This blind spot develops when damaged areas of the macula can no longer process visual information properly. The leaking fluid and blood from abnormal vessels can destroy light-sensitive cells in the macula, creating a void in your central vision. The scotoma may appear as a gray, black, or completely empty area right where you’re trying to focus.

The impact of a central scotoma can be profound. You may find yourself turning your head or adjusting your gaze to see around the blind spot, using your peripheral vision to compensate. Simple tasks like threading a needle, dialing a phone, or recognizing faces become challenging as the scotoma obscures critical visual details.

4. Rapid Vision Deterioration

Unlike dry macular degeneration, which typically progresses slowly over years, wet AMD is characterized by rapid vision loss. You may notice significant changes in your vision over just days, weeks, or a few months. This accelerated deterioration is what makes wet macular degeneration a medical urgency requiring immediate attention.

The speed of vision loss occurs because abnormal blood vessels can leak large amounts of fluid quickly, causing sudden swelling and damage to the macula. In some cases, these vessels may also bleed, leading to more immediate and severe visual impairment. The rapidity of these changes distinguishes wet AMD from many other eye conditions.

Warning signs of rapid progression:

• Sudden worsening of blurriness or distortion
• Abrupt appearance or enlargement of a central blind spot
• Dramatic decrease in reading ability within a short timeframe
• Noticeable vision changes from one week to the next

If you experience rapid vision changes, it’s essential to seek immediate evaluation from an eye care professional, as timely intervention can help slow or stop further vision loss.

5. Difficulty Recognizing Faces

Many people with wet macular degeneration report increasing difficulty recognizing familiar faces, even of close family members and friends. This symptom, known as prosopagnosia when severe, occurs because facial recognition requires the detailed central vision that wet AMD impairs.

When you look directly at someone’s face, the central scotoma or blurred vision may obscure critical features like eyes, nose, and mouth—the very details your brain uses to identify individuals. You might find yourself relying more on contextual clues such as voice, hairstyle, clothing, or body shape to recognize people.

This symptom can be particularly distressing socially and emotionally. You may:

• Fail to recognize friends or relatives in public settings
• Need to see people from the side or at a distance to identify them
• Struggle to make eye contact during conversations
• Feel embarrassed or isolated due to inability to recognize people

Face recognition difficulties often serve as a wake-up call that prompts people to seek medical evaluation, making it an important symptom to recognize.

6. Colors Appear Less Vivid or Faded

A subtle but significant symptom of wet macular degeneration is the fading or dulling of colors. You may notice that colors that once appeared bright and vibrant now seem washed out, muted, or less distinct. This change in color perception results from damage to the cone cells in the macula, which are responsible for color vision.

As fluid accumulation and abnormal blood vessel growth damage the retinal cells, their ability to process color information diminishes. You might observe that:

• Reds and greens appear less saturated
• Distinguishing between similar colors becomes more challenging
• Overall visual scenes lack the richness and depth they once had
• Colors in one eye appear different from the other eye

While this symptom may develop more gradually than some others, it significantly impacts quality of life. Activities like cooking (judging food doneness), selecting clothing, or enjoying art and nature become less satisfying. Color vision changes may also affect safety, making it harder to see traffic lights or warning signs clearly.

7. Increased Difficulty with Low Light Conditions

People with wet macular degeneration often experience increased difficulty adapting to low light environments and may require brighter lighting for everyday tasks. This symptom occurs because the damaged macula becomes less efficient at processing the limited visual information available in dim conditions.

You may notice:

• Needing significantly brighter lights for reading or close work
• Trouble navigating in dimly lit rooms or at night
• Longer time needed for eyes to adjust when moving from bright to dark spaces
• Difficulty seeing in restaurants, theaters, or other low-light environments
• Increased glare sensitivity from bright lights

This reduced adaptability stems from the macula’s compromised function. The abnormal blood vessels and resulting fluid accumulation interfere with the retina’s ability to process light signals efficiently, particularly when those signals are already diminished by poor lighting. Many people compensate by installing brighter bulbs throughout their homes or carrying portable lighting devices.

Main Causes of Wet Macular Degeneration

Wet macular degeneration develops when abnormal blood vessels grow beneath the retina in a process called choroidal neovascularization. While the exact triggers aren’t fully understood, several factors contribute to this condition:

Age: The primary risk factor for wet AMD is age. The condition predominantly affects people over 50, with risk increasing significantly after age 60. Age-related changes in the eye’s structures and reduced cellular repair mechanisms make older individuals more susceptible.

Progression from Dry AMD: Wet macular degeneration typically develops in eyes that already have dry AMD. The presence of drusen (yellow deposits beneath the retina) and retinal pigment changes indicate increased risk for progression to the wet form.

Genetic Factors: Family history plays a significant role. If you have close relatives with AMD, your risk increases substantially. Specific genetic variations, particularly in complement factor genes, have been linked to higher susceptibility to both dry and wet AMD.

Smoking: Tobacco use is one of the strongest modifiable risk factors for wet macular degeneration. Smokers are 2-4 times more likely to develop AMD than non-smokers, and smoking accelerates disease progression.

Cardiovascular Factors: Conditions affecting blood vessels, such as high blood pressure, high cholesterol, and cardiovascular disease, increase the risk of developing wet AMD. The health of blood vessels throughout the body correlates with retinal vessel health.

Race and Ethnicity: Caucasians have a higher risk of developing AMD compared to African Americans, Hispanics, and Asians, though the condition can affect people of all ethnic backgrounds.

Other Contributing Factors:

• Obesity, particularly excess abdominal fat
• Prolonged sun exposure and UV radiation
• Poor diet lacking in antioxidants and omega-3 fatty acids
• Light-colored eyes (blue or green)
• Female gender (slightly higher risk than males)

Prevention Strategies

While you cannot completely prevent wet macular degeneration, especially if you have genetic predisposition or dry AMD, you can take steps to reduce your risk and potentially slow progression:

Quit Smoking: If you smoke, quitting is the single most important action you can take to reduce your AMD risk. The benefits begin almost immediately and continue to increase over time.

Maintain a Healthy Diet: Consume a diet rich in leafy green vegetables, fish high in omega-3 fatty acids, and colorful fruits and vegetables. The antioxidants lutein, zeaxanthin, vitamins C and E, and zinc support retinal health. Foods like spinach, kale, salmon, and nuts are particularly beneficial.

Regular Eye Examinations: Schedule comprehensive eye exams at least annually if you’re over 50 or have risk factors for AMD. Early detection of dry AMD or early signs of wet AMD conversion allows for timely intervention. Your eye doctor may recommend more frequent monitoring if you have intermediate AMD.

Use an Amsler Grid at Home: If you have dry AMD or are at high risk, your eye doctor may recommend daily self-monitoring with an Amsler grid. This simple test can help you detect early changes that might indicate conversion to wet AMD, prompting immediate medical attention.

Protect Your Eyes from UV Light: Wear sunglasses that block 100% of UVA and UVB rays when outdoors. A wide-brimmed hat provides additional protection. Long-term UV exposure may contribute to AMD development.

Manage Cardiovascular Health: Control blood pressure, cholesterol, and blood sugar levels. Maintain a healthy weight through balanced diet and regular exercise. What’s good for your heart is generally good for your eyes.

Consider Nutritional Supplements: If you have intermediate or advanced dry AMD in one eye, your doctor may recommend AREDS2 formula supplements containing specific vitamins and minerals. However, always consult with your healthcare provider before starting any supplementation regimen, as these are not appropriate for everyone.

Exercise Regularly: Regular physical activity improves circulation and may reduce AMD risk. Aim for at least 150 minutes of moderate aerobic activity weekly.

Frequently Asked Questions

What is the difference between wet and dry macular degeneration?

Dry AMD is more common (85-90% of cases) and progresses slowly, caused by thinning of the macula and drusen deposits. Wet AMD (10-15% of cases) involves abnormal blood vessel growth that leaks fluid or blood, causing rapid vision loss. Wet AMD typically develops in people who already have dry AMD and is more severe but less common.

How quickly does wet macular degeneration progress?

Wet AMD can progress very rapidly, with noticeable vision changes occurring within days to weeks. Unlike dry AMD, which may take years to cause significant vision loss, wet macular degeneration is considered a medical urgency. The speed of progression varies among individuals but generally requires prompt medical attention to prevent severe permanent vision loss.

Can wet macular degeneration affect both eyes?

Yes, wet AMD can affect both eyes, though it often starts in one eye before involving the other. If you have wet AMD in one eye, you have an increased risk of developing it in the second eye. This is why careful monitoring of both eyes is essential, and why you should test each eye separately when using an Amsler grid.

Is wet macular degeneration the same as a cataract?

No, these are completely different conditions. Cataracts involve clouding of the eye’s natural lens and affect overall vision quality, while wet AMD specifically damages the macula, affecting central vision. Cataracts are treatable with surgery, whereas wet AMD requires different interventions. However, it’s possible to have both conditions simultaneously, as both become more common with age.

How is wet macular degeneration diagnosed?

Diagnosis typically involves a comprehensive eye examination including visual acuity testing, dilated eye exam, Amsler grid testing, optical coherence tomography (OCT) to create detailed retinal images, and fluorescein angiography to visualize blood vessel abnormalities. Your eye doctor may use multiple tests to confirm wet AMD and assess its severity.

Will I go completely blind from wet macular degeneration?

Wet AMD typically does not cause complete blindness. It affects central vision while peripheral vision usually remains intact. This means you won’t lose all vision, but tasks requiring detailed central vision (reading, driving, recognizing faces) become difficult. With modern treatments, many people can maintain functional vision, especially when the condition is caught and treated early.

Can wet macular degeneration be reversed?

Wet AMD cannot be completely reversed, but early intervention can stop or slow vision loss and, in some cases, improve vision. The goal of treatment is to stop abnormal blood vessel growth and leakage, stabilize vision, and prevent further damage. This is why recognizing symptoms early and seeking prompt medical care is crucial.

Should I monitor my vision at home if I have risk factors?

Yes, if you have dry AMD or other risk factors, your doctor may recommend daily self-monitoring using an Amsler grid. Check each eye separately and watch for distorted lines, blank spots, or blurred areas. Any sudden changes should prompt immediate contact with your eye care professional, as early detection of wet AMD conversion allows for timely intervention.
