Age-related macular degeneration (AMD) is a chronic eye disease that affects the macula. It causes central vision loss. There are two types of AMD: dry and wet. Wet AMD, the severe type, lets abnormal blood vessels grow in the eye. This can make vision loss fast if not treated quickly. An innovative treatment, stem cell therapy, offers hope in restoring vision for those with wet AMD.
Key Takeaways:
- Wet AMD is a more severe form of age-related macular degeneration characterized by the growth of abnormal blood vessels in the eye.
- Symptoms of wet AMD include blurry central vision, distortion of straight lines, and dark spots in the visual field.
- Several risk factors for wet AMD have been identified, including aging, genetics, smoking, high blood pressure, obesity, and a poor diet.
- Diagnosis of wet AMD involves comprehensive eye examinations and imaging tests to evaluate the severity of the disease.
- Treatment options for wet AMD include anti-vascular endothelial growth factor medications, photodynamic therapy, laser surgery, stem cell therapy, and implantable miniature telescopes.
Types of Age-related Macular Degeneration
Age-related macular degeneration (AMD) is a common eye disease. It affects the macula, causing central vision loss. There are two types: dry AMD and wet AMD. Knowing these differences is key for diagnosis and treatment.
Dry AMD
Dry AMD is the most common type. It gets worse slowly and has drusen, yellow deposits, in the macula. Over time, the macula thins and vision gets worse.
Wet AMD
Wet AMD is rarer and causes vision loss faster. It happens when abnormal blood vessels under the retina leak into the macula. This leads to a swollen and damaged macula, affecting central vision.
Unlike dry AMD, wet AMD’s effects worsen quickly if not treated. Detecting and treating it early is essential for preserving vision and eye health.
An image can help us see the differences between dry and wet AMD. The picture above shows a healthy eye compared to one with AMD.
Now we’ll look into the symptoms and how wet AMD progresses in the next section.
Symptoms and Progression of Wet AMD
Age-related macular degeneration (AMD) is a serious eye disease that can lead to vision loss. It’s crucial to know the signs and progression of wet AMD for early detection. This way, with quick medical attention, effective treatments can be started to handle the issue.
Common Symptoms of Wet AMD
Wet AMD shows different symptoms that can harm central vision and your daily life. Signs may include:
- Blurred central vision
- Distortion of straight lines
- Dark spots or blind spots in the visual field
Blurred vision is key in wet AMD. It makes it hard to see details like words or faces clearly. Seeing straight lines as curved is a common issue. And dark or blind spots in your vision may cause you to miss parts of what you’re looking at.
Progression of Wet AMD
Wet AMD gets worse over time if not treated. It’s caused by abnormal blood vessels that leak and cause scarring, hurting your central vision.
As it advances, you might lose a lot of your vision. This can change how you read, drive, recognize people, and do daily tasks. So, quick medical help when you notice symptoms is very important.
Seeking Medical Attention for Wet AMD
If you or a loved one show signs of wet AMD, seeing an eye doctor is a must. Early treatment can slow down the disease and save your vision.
Doctors will do many tests in an eye exam to understand your condition. After diagnosing you, they’ll suggest ways to treat and manage your symptoms.

Wet AMD is a progressive disease, with symptoms worsening over time if left untreated. The abnormal growth of blood vessels behind the macula can result in fluid leakage, scarring, and damage to the central vision area. |
If you or a loved one experience symptoms of wet AMD, seek medical attention promptly for an accurate diagnosis and appropriate treatment options. An eye care professional can conduct tests and comprehensive eye examinations to assess the severity of the condition and provide suitable treatment options. |
Causes and Risk Factors of Wet AMD
Wet AMD’s exact cause, known as neovascular AMD, is a mystery. But, we do know of several factors that make getting this eye disease more likely. Knowing these risks helps people act to avoid wet AMD and keep their eyesight safe.
The key factors and causes of wet AMD include:
Aging
Getting older raises the chance of having wet AMD. Changes in the eye’s tissues and blood vessels as we age can lead to unhealthy blood vessels in the macula. This can cause a loss of vision.
Genetics
Your genes play a part in whether you might get wet AMD. Certain versions of genes raise the risk. If AMD runs in your family, you could be at higher risk for the wet form.
Smoking
Smoking makes it much more likely to get wet AMD. This is because tobacco’s chemicals can hurt the retina’s blood vessels. This leads to the growth of unhealthy blood vessels and loss of vision.
High Blood Pressure
High blood pressure that isn’t controlled can worsen wet AMD. It harms the eye’s tiny blood vessels, making it more likely for bad blood vessels to grow.
Obesity
Carrying too much weight also boosts the risk of wet AMD. It causes ongoing inflammation and changes in metabolism. Both can hurt blood vessel health and cause abnormal blood vessels to form in the eyes.
Diet
Eating foods full of saturated fats, trans fats, and processed meats can raise your wet AMD risk. These foods add to inflammation and stress in your body. This can speed up the disease.
To avoid wet AMD and keep your eyes healthy, follow these steps:
- Stop smoking to lower your wet AMD risk.
- Stay at a healthy weight with regular workout and a good diet.
- Eat lots of fruits, veggies, whole grains, and lean proteins to help your eyes.
- Don’t eat too much saturated fats, trans fats, or processed meats.
- Keep an eye on your blood pressure and work on keeping it normal with lifestyle changes or medicine, if your doctor advises.
By managing these risk factors and living a healthy life, you can lower your chance of getting wet AMD. This will help keep your eyes healthy for a long time.
Diagnosis of Wet AMD
Getting a diagnosis of wet AMD is key in keeping your eyesight safe. Doctors perform a detailed eye check to see how bad the condition is. They also pick the best treatment for you. These checks usually include:
- Visual acuity testing: This measures how well you can see things at different distances. It shows how much vision loss you have from wet AMD.
- Optical coherence tomography (OCT): Doctors use this test to get detailed pictures of your retina with light waves. This shows if there is any fluid build-up or damage in your macula. It’s really helpful in diagnosing and watching over wet AMD.
- Angiography: In this test, a dye is put into your blood to make your retina’s blood vessels stand out. It spots any new or leaky blood vessels, helping to confirm wet AMD.
Spotting wet AMD early is vital for a good outcome. Detecting abnormal blood vessels and gauging disease severity are critical. This allows doctors to create a treatment plan just for you, helping to control wet AMD well.
Treatment Options for Wet AMD
Managing wet AMD includes several treatment options. These aim to save and better the patient’s vision. The treatments are:
1. Anti-vascular endothelial growth factor (Anti-VEGF) medications
Anti-VEGF drugs are used to slow the growth of abnormal blood vessels. They also lower fluid leakage in the eye. These drugs are usually given as shots right into the eye. They’ve shown to help keep vision from worsening or even improve it in some cases.
2. Photodynamic therapy
Photodynamic therapy uses a special medicine called verteporfin. The drug is put into a vein in the arm and then travels through the body. A laser pointed at the eye then activates this medicine. It helps get rid of abnormal blood vessels, which can improve vision for some people.
3. Laser surgery
Laser surgery can target and seal the leaky blood vessels in the eye. A laser is aimed at these vessels to close them off and stop fluid leaks. Sometimes, this surgery is done together with other treatments for the best results.
Your ophthalmologist will choose a treatment based on how bad the condition is, where the problem is in the eye, and your own health. They will decide the best way forward. Keep up with your check-ups so your doctor can see how you are doing and adjust your treatment plan if needed.
Seeking out treatment can help a lot. With the right care, people with wet AMD can live better and keep as much of their vision as they can. Catching the problem early, and staying with your treatment plan is very important for the best results.
Stem Cell Therapy for Wet AMD
Stem cell therapy is a new, hopeful way to deal with wet age-related macular degeneration (AMD). It uses stem cells to fix and grow back damaged retinal tissue. This helps to better eyesight and slow down the disease. Though we’re still studying it, early findings are promising for wet AMD patients.
Some people see better after stem cell therapy. It uses the power of stem cells to repair the retina. This can make eyesight better and improve life for those with wet AMD.
But, stem cell therapy isn’t widely available yet for wet AMD. More studies are needed to be sure it works well, is safe, and how long the effects last.
Potential Advantages of Stem Cell Therapy for Wet AMD
Stem cell therapy has many possible benefits for wet AMD:
- Regeneration of damaged tissue: Stem cells can turn into many cell types, including those in the retina. Adding healthy stem cells to the retina may fix the damaged area caused by abnormal blood vessels in wet AMD.
- Reduced reliance on lifelong treatments: Current options for wet AMD need regular injections or medicines. Stem cell therapy might only require one treatment, reducing the need for ongoing care.
- Potential for personalized treatment: Each person’s stem cell therapy can be customized. This means it can be tailored to meet the specific needs of their wet AMD.
The Future of Stem Cell Therapy for Wet AMD
Stem cell therapy is still new for treating wet AMD. It promises a hopeful future for this condition that affects eyesight. As research and technology improve, we’ll learn more about how well it works and its effects over time.
