Wet age-related macular degeneration (wet AMD) is a serious eye condition that can lead to vision loss if left untreated. It occurs when abnormal blood vessels grow beneath the retina, leaking fluid and blood, which damages the macula—the part of the eye responsible for sharp central vision. The condition can cause blurry vision, dark spots, and distortion, making everyday activities such as reading or recognizing faces challenging. Early diagnosis and treatment are crucial to managing wet AMD and preserving vision.

If you or a loved one is experiencing symptoms such as blurred or distorted vision, it's essential to seek professional medical advice to explore the available treatment options.
Understanding Wet AMD Treatments
Advancements in medical science have led to various effective treatments that can slow the progression of wet AMD and, in some cases, improve vision. The primary treatment options include:
1. Anti-VEGF Injections
One of the most common and effective treatments for wet AMD is anti-VEGF (vascular endothelial growth factor) injections. VEGF is a protein that promotes the growth of abnormal blood vessels in the eye. Anti-VEGF medications such as ranibizumab (Lucentis), aflibercept (Eylea), and bevacizumab (Avastin) work by blocking this protein, reducing leakage and swelling in the retina. These injections are administered directly into the eye by an ophthalmologist, usually on a monthly or bi-monthly basis. Many patients experience a stabilization of their vision, and some may even notice an improvement.
2. Photodynamic Therapy (PDT)
Photodynamic therapy is another option for treating wet AMD. This procedure involves injecting a light-sensitive drug into the bloodstream, which then travels to the abnormal blood vessels in the eye. A laser is used to activate the drug, which helps seal off the leaking vessels and prevent further damage. PDT is typically used in combination with anti-VEGF injections for better results, especially in cases where injections alone are not sufficient.
3. Laser Therapy
In some cases, laser photocoagulation therapy may be recommended to target and destroy abnormal blood vessels. This method uses a high-energy laser beam to seal the leaking vessels and prevent further damage to the macula. While effective, laser therapy can sometimes cause scarring and is generally used in select cases where the abnormal blood vessels are not directly beneath the central vision area.
4. Lifestyle and Nutritional Support
In addition to medical treatments, lifestyle changes and dietary adjustments can play a supportive role in managing wet AMD. A diet rich in antioxidants, vitamins C and E, zinc, and omega-3 fatty acids can help slow the progression of the disease. Supplements such as the AREDS (Age-Related Eye Disease Study) formula, which contains lutein and zeaxanthin, are often recommended to support eye health. Quitting smoking, maintaining a healthy weight, and protecting the eyes from excessive UV exposure can also help in managing the condition.
Recognizing the Symptoms Early
The earlier wet AMD is diagnosed, the better the chances of preserving vision. Some of the common symptoms include:
- Blurry or wavy vision
- Dark or empty spots in the central vision
- Difficulty recognizing faces or reading
- Colors appearing dull or washed out
If you notice any of these symptoms, it is important to visit an eye specialist for a thorough examination, including optical coherence tomography (OCT) scans and fluorescein angiography to detect fluid buildup and abnormal blood vessels.
The Importance of Regular Eye Exams
Routine eye exams are vital for early detection of wet AMD, especially for individuals over the age of 50 or those with a family history of macular degeneration. Regular monitoring allows for timely intervention and better management of the disease, preventing severe vision loss.
Conclusion
Wet AMD can be a challenging condition, but with the right treatment options, it is possible to slow its progression and maintain functional vision. Whether through anti-VEGF injections, laser treatments, or lifestyle adjustments, exploring the available options is key to preserving eye health. If you or someone you know is experiencing symptoms of wet AMD, taking action early can make a significant difference in maintaining a better quality of life.
