Wet Macular Degeneration
What is Wet Macular Degeneration?
Also known as neovascular age-related macular degeneration or AMD, this is a progressive cause of central vision loss that primarily affects older adults. Unlike the more common dry form, the wet type can progress rapidly and requires prompt medical attention to manage its effects and preserve your sight.
Dry AMD is the more common type and develops slowly as the macula thins over time, causing gradual vision changes. In contrast, wet AMD involves the growth of new, leaky blood vessels that can cause sudden and severe vision loss if not treated. While only about 10 to 15 percent of people with AMD have the wet form, it accounts for approximately 90 percent of all cases of severe vision loss related to the condition.
This condition mainly impacts people over the age of 50, with the risk increasing sharply as you get older. Statistics show that about 1 in 8 people over 60 have some form of AMD. The risk is also higher for people of Caucasian descent, women, and individuals with a family history of macular degeneration. Lifestyle factors, especially smoking, also play a significant role.
The macula is a small spot in the center of your retina responsible for sharp, detailed, straight-ahead vision. It allows you to see fine details, colors, and recognize faces. When wet AMD damages this area with leaking fluid and blood, it can create blind spots, distortions, and a loss of the central vision crucial for most daily activities.
In wet AMD, the body attempts to supply more oxygen and nutrients to the retina by growing new blood vessels. However, these new vessels are fragile and grow in the wrong place. This process, called choroidal neovascularization, leads to leakage of blood and fluid, which damages the delicate retinal tissue, causes swelling, and can lead to scar formation that permanently harms your vision.
With central vision loss, patients may struggle with reading, writing, recognizing faces, driving, and even simple tasks like cooking or managing medications. While peripheral, or side, vision often remains intact, the loss of central sharpness greatly affects a person's independence and confidence in performing daily routines.
Causes and Risk Factors
Wet AMD develops when fragile blood vessels form under the retina and begin to leak. While the exact trigger is complex, a combination of genetic, environmental, and lifestyle factors contributes to the risk of developing the condition.
The primary cause of wet AMD is the abnormal growth of blood vessels in response to signals that the retina is not receiving enough oxygen or nutrients. A protein called VEGF, or vascular endothelial growth factor, plays a key role in stimulating this harmful growth. In many cases, wet AMD develops in an eye that has already been weakened by the effects of dry AMD.
As we age, waste products can build up under the retina, forming yellow deposits called drusen. These deposits can interfere with the normal function of the retina and may trigger the inflammatory and vascular changes that lead to the development of wet AMD. The older you are, the higher your risk.
Research has identified several genes that increase the risk of developing AMD. If you have a parent or sibling with macular degeneration, your own risk of developing the condition is three to four times higher than someone without a family history. However, having these genes does not guarantee you will get AMD.
Several factors in your daily habits can significantly increase your risk of developing wet AMD.
- Smoking is the single biggest controllable risk factor, increasing your chances by up to four times.
- Poor diet, especially one low in antioxidants, leafy greens, and omega-3 fatty acids, may increase your risk.
- High blood pressure can affect the health of blood vessels throughout your body, including your eyes.
- High cholesterol may contribute to the formation of deposits under the retina.
- Obesity can increase inflammation in the body, which is linked to AMD.
- Long-term sun exposure without proper eye protection may contribute to retinal damage over time.
Symptoms to Watch For
The symptoms of wet macular degeneration often appear suddenly and can worsen quickly, so recognizing them early is critical for seeking treatment and protecting your vision. These changes typically affect your central vision while your peripheral vision remains normal.
One of the first signs people often notice is that straight lines appear wavy or distorted, a symptom known as metamorphopsia. You might see this when looking at a door frame, window blinds, or a grid of tiles. Colors may also seem less bright or washed out, and you may find it harder to read small print, even with your usual glasses.
As the condition progresses, a blurry, dark, or empty spot may form in the center of your vision. This central blind spot, called a scotoma, can make it difficult to recognize faces, read a clock, or drive. You might find yourself needing to turn your head to use your side vision to see things directly in front of you.
A sudden and rapid decline in your central vision is a key indicator of wet AMD. This happens because the leaking blood vessels cause quick swelling in the macula. Unlike dry AMD, which can progress slowly over years, the vision loss from wet AMD can occur within days or weeks, making it a medical emergency that requires immediate attention from an eye doctor.
Your eye doctor may give you an Amsler grid to monitor your vision at home between appointments. This simple tool is a pattern of straight lines, and looking at it daily can help you detect any new wavy lines, blurry areas, or missing spots in your vision. Reporting any new changes to your doctor immediately is crucial.
How is Wet Macular Degeneration Diagnosed?
A diagnosis of wet AMD requires a comprehensive eye exam by a retina specialist. The process involves a thorough check of your vision and the use of sophisticated imaging to confirm the presence of abnormal blood vessels and fluid leakage.
Your eye doctor will start with a comprehensive eye exam, which includes checking your vision on an eye chart and examining the front and back of your eyes. They will use special drops to dilate your pupils, which allows for a much clearer view of your retina and macula. This part of the exam may make your vision blurry for a few hours afterward.
Several specialized, painless tests help doctors see exactly what is happening in your retina.
- Optical Coherence Tomography, or OCT, is a quick, non-invasive scan that creates detailed, cross-sectional images of your retina. It is the best way to show fluid buildup or swelling in the macula.
- Fluorescein Angiography uses a special vegetable-based dye injected into a vein in your arm. As the dye travels through the blood vessels in your eye, a special camera takes pictures to highlight any abnormal vessels or areas of leakage.
- Fundus Photography involves taking high-resolution pictures of the back of your eye to document changes over time and monitor the condition.
Most diagnostic visits take about one hour. Be sure to bring a list of all medications you take, including vitamins. Because your pupils will be dilated, your vision will be blurry and sensitive to light for several hours, so it is essential to have someone drive you home from your appointment.
Treatment Options for Wet Macular Degeneration
Modern treatments for wet AMD are highly effective and aim to stop the growth of abnormal blood vessels and reduce leakage. The goal is to stabilize or, in many cases, even improve vision, but treatment requires ongoing monitoring and a partnership with your retina specialist.
The standard and most effective treatment for wet AMD is injections of medication into the eye. These medications, including Avastin, Lucentis, Eylea, and Vabysmo, block the VEGF protein that signals your body to grow new, leaky blood vessels. The injections are given with a very thin needle after the eye is completely numbed, and most patients experience little to no discomfort.
Initially, injections are often given monthly for the first few months. Based on how your eye responds, the schedule may be extended to every few months. Your eye doctor will monitor your progress closely with regular OCT scans and vision tests to create a personalized treatment plan that is effective while minimizing your number of office visits.
In certain cases, laser treatments may be used, though they are much less common than injections. Photodynamic therapy, or PDT, uses a light-sensitive drug activated by a cool laser to seal off leaking vessels. Traditional laser photocoagulation may be used when the abnormal vessels are not directly under the center of the macula.
After an injection, it is common to experience temporary discomfort, redness, or the sensation of having something in your eye, which usually resolves within a day. Serious complications like infection are very rare but require immediate attention if you experience severe pain, discharge, or a significant decrease in vision.
Research is constantly advancing. New treatments being studied include longer-lasting drug delivery systems that can be implanted in the eye, as well as gene therapy approaches that could provide more permanent effects. These future options offer hope for even more effective and convenient treatments.

Frequently Asked Questions About Wet Macular Degeneration
Patients often have questions about managing wet AMD and its impact on their lives. Addressing these common concerns can help reduce anxiety and empower you to take an active role in your eye health. Patients throughout the Waterbury area, including those in Naugatuck, Watertown, and Southbury, frequently ask us these questions.
While it cannot be fully prevented, you can lower your risk by adopting healthy habits. Not smoking, eating a nutritious diet, controlling your blood pressure, and getting regular eye exams are the best ways to protect your eyes. Early detection is key to preventing severe vision loss.
It is very rare to go completely blind from wet AMD. The condition affects your central vision but usually spares your peripheral, or side, vision. While you may lose the ability to read or drive, you will likely retain enough sight to navigate your surroundings and maintain a degree of independence.
Without treatment, wet AMD can progress very rapidly, sometimes causing significant vision loss within weeks or months. This is why it is considered a medical emergency. However, with timely and consistent treatment, the progression can be slowed significantly or even stopped in many cases.
Genetics play a significant role. If you have close family members with AMD, your risk is higher. However, genes are only part of the story. Lifestyle factors like smoking and diet also play a major role in whether the condition develops.
Standard glasses and contact lenses cannot correct vision loss from wet AMD because the damage is to the retina itself, not the lens or cornea. However, specialized low-vision devices, such as magnifiers and telescopic glasses, can help maximize your remaining vision.
The AREDS2 study showed that a specific formula of vitamins and minerals, including Vitamins C and E, zinc, copper, lutein, and zeaxanthin, can help slow the progression of intermediate to advanced dry AMD, which can reduce the risk of developing wet AMD. You should always consult your eye doctor before starting any supplements.
Driving safety depends entirely on how much vision loss you have and whether you meet the legal vision requirements in your state. With mild central vision loss, some people can continue to drive safely, especially in familiar areas during the day. Your eye doctor can help assess whether driving is still safe for you.
Yes, wet AMD is a chronic condition that can become active again even after a period of stability. This is why ongoing monitoring and maintenance treatments are usually necessary to prevent new blood vessel growth and preserve your vision long-term.
Family can provide crucial support by helping with transportation to appointments, encouraging adherence to treatment, assisting with home modifications for safety, and providing emotional encouragement. Learning about the condition together can help everyone adapt to the changes.
Most insurance plans, including Medicare, cover the FDA-approved treatments for wet AMD, such as anti-VEGF injections. Your retina specialist's office can help you navigate any questions about your specific coverage or the need for prior authorization.
Any sudden change in your vision, especially if you already have AMD, should be treated as an emergency. Contact your eye doctor's office immediately, even if it is after hours. Prompt treatment is the best way to prevent permanent vision loss.
