Age-related macular degeneration (AMD) affects the macula, leading to central vision loss. It has two types: dry and wet. Dry AMD, also known as atrophic AMD, happens slowly. It is marked by the macula getting thinner. Wet AMD, less common, leads to faster vision loss. This type occurs when abnormal blood vessels damage the macula’s back area. While advanced dry AMD has no cure, there are treatments like stem cell therapy for wet AMD.
Key Takeaways:
- Age-related macular degeneration (AMD) leads to central vision loss by affecting the macula.
- The two types of AMD are dry (atrophic) and wet. Dry AMD advances slowly, while wet AMD speeds up vision loss.
- Hope for better AMD treatments exists, with stem cell therapy being a promising area for wet AMD.
- For those at risk of AMD, early detection and proactive care are crucial.
- Managing AMD symptoms and slowing its progress involves regular eye checks and certain lifestyle changes.
Symptoms of Age-Related Macular Degeneration Dry
Age-related macular degeneration (AMD) is an eye disease that gets worse over time. It mainly affects the macula, the central part of your eye. This leads to a slow loss of your clear, straight-ahead vision. In dry AMD, the signs get more noticeable as the disease goes on.
Early Stage
At first, dry AMD may not show any symptoms. Or you might only notice them a little bit. You could find that things look more blurry than usual. Also, it might be harder to see well in places with low light.
Intermediate Stage
When dry AMD gets to the middle stage, you might see straight lines as wavy or bending. This can make pictures look wrong and cause troubles when reading or looking at patterns.
Advanced Stage
In the end stage of dry AMD, the symptoms are more serious. You might see blank areas or experience more blurriness in your central vision. Straight lines can start to look bent or twisted. Colors might not seem as bright as they used to. And seeing clearly in low light can become very hard. These problems can make daily life challenging.
If you notice any of these symptoms, it’s important to see an eye doctor. They will do tests to find out what’s happening. This could include using eye drops to make your pupils bigger, or doing imaging tests like optical coherence tomography (OCT). Catching dry AMD early is key to managing it successfully.
Symptoms of Age-Related Macular Degeneration Dry
| Stage | Symptoms |
|---|---|
| Early | No symptoms or mild blurriness Difficulty seeing in low light |
| Intermediate | Wavy or distorted straight lines Difficulties in reading or recognizing patterns |
| Advanced | Blurred or blank spots in central vision Distorted or crooked lines Faded colors Difficulties in seeing in low light |
Causes and Risk Factors of Age-Related Macular Degeneration Dry
Age-related macular degeneration dry (AMD) is a complex eye disease with many risk factors. Knowing these can help us prevent and manage the condition. While we don’t fully understand the exact causes, certain things make it more likely you’ll get AMD.
Age, Genetics, and Gender
The risk of getting AMD dry increases with age, especially after 60. The macula, which is essential for seeing fine details, changes over time. This makes older individuals more prone to the disease.
Having a family history of AMD can also raise your risk. So, if someone related to you has had it, you should be especially watchful.
Women seem to develop AMD more often than men. This might be because of hormonal changes or genetic differences.
High Blood Pressure and Obesity
If you have high blood pressure, you might also be at risk for AMD dry. This is because high blood pressure can harm the tiny blood vessels in your eyes.
Being obese is another factor that could increase your risk. Extra weight can cause inflammation and stress on your cells. This can speed up the progression of the disease.
UV Rays Exposure and Lifestyle Factors
Too much UV ray exposure, like from the sun, can damage your macula. It’s essential to protect your eyes from UV rays to lower your AMD risk.
Your lifestyle choices matter too. For instance, smoking is harmful and can increase your risk of AMD. It does damage to your blood vessels and leads to more stress on your cells.
Eating foods high in fats and processed meats can also raise your risk. But if you eat plenty of fruits, veggies, and fish, your chances of getting AMD may be lower. These foods are loaded with the nutrients your eyes need.
Link to Cardiovascular Disease
Recently, scientists have found a link between AMD dry and heart disease. They both share common risks like high blood pressure, obesity, and smoking.
So, if you have heart problems, you might also have a higher chance of getting AMD. This shows why keeping your heart healthy is also good for your eyes.
Knowing about these risks is helpful, but it doesn’t mean you’ll get AMD. Regular eye checks, healthy habits, and avoiding UV rays can reduce your risk. And managing your health conditions well is key to dealing with AMD if it shows up.
Diagnosis of Age-Related Macular Degeneration Dry
Dry AMD requires several tests to diagnose it correctly. Doctors use these to see how severe the condition is. They also decide on the best treatment. These tests give the eye doctor a full picture of the patient’s eye health.
Visual Acuity Testing
The Snellen chart checks how well a person sees at different distances. This shows how much central vision has been lost due to dry AMD.
Perimetry
Perimetry tests a patient’s side vision, finding any peripheral sight loss. It shows the full impact of dry AMD on vision.
Optical Coherence Tomography (OCT)
OCT is a special eye scan that looks at the retina in detail. It helps find any thin spots or problems. Doctors use OCT to measure the macula’s thickness and track any changes.
Amsler Grid Test
The Amsler grid is a grid pattern that patients with dry AMD look at. It lets them notice any warped or missing areas in their vision. This is key for finding and following any macula changes.
Fluorescein Angiography
In fluorescein angiography, a special dye is injected into a patient’s arm. The dye shows up in eye blood vessels, which are photographed. This test spots wet AMD signs. It helps doctors tell wet from dry AMD.
Tests like visual acuity, perimetry, OCT, Amsler grid, and fluorescein angiography are vital for diagnosing dry AMD well. They help in choosing the right treatment.
Treatment Options for Age-Related Macular Degeneration Dry
Right now, there’s no cure for dry AMD. But we do have ways to slow it down and manage its effects. New research has brought about some exciting treatments for a specific type called geographic atrophy.
Pegcetacoplan (Syfovre) and avacincaptad pegol (Izervay) are looking very promising. Doctors give these treatments with shots in the eye. They focus on stopping the damage to the cells in the eye’s retina.
Lifestyle changes and special tools can also help deal with dry AMD. Here are a few ideas:
- Use magnifying tools to see better and read more easily.

| Avacincaptad pegol (Izervay) | Direct eye injections | Every 8 weeks |
Treatment Options for Wet Age-Related Macular Degeneration
Unlike dry AMD, there are ways to treat wet AMD. The main treatment is anti-VEGF medication. This medicine is injected into the eye. It helps stop the growth of bad blood vessels and makes them leak less.
There’s also photodynamic therapy. It uses a laser to destroy the extra blood vessels.
These treatments slow down wet AMD. They can keep you from losing more vision.
Anti-VEGF Medication
Anti-VEGF drugs are the top choice for treating wet AMD. They stop a protein that makes unwanted blood vessels grow. By doing this, these drugs can save your sight and protect your eye’s macula. They’re given through eye injections. A doctor will decide how often you need these shots.
Photodynamic Therapy
Another option is photodynamic therapy. It uses a special medication called verteporfin. This medication, when activated by a laser, closes off bad blood vessels in your eye. This method can help keep your central vision clear. But, it’s not for everyone. Your eye doctor will decide if it’s right for you.
Combination Treatment
Sometimes, using both anti-VEGF drugs and photodynamic therapy works best. This strategy can better control wet AMD and lower loss of vision. Your eye specialist will check how severe your case is. They will then create a treatment plan just for you.
Follow-Up and Monitoring
After the first round of treatments, keep up with your eye doctor visits. These check-ups are crucial to see if the treatment is working and if more is needed. It’s key to stay on top of your visits. Tell your eye doctor about any new vision problems right away.
Stem Cell Therapy for Age-Related Macular Degeneration
Stem cell therapy is showing a lot of promise in treating AMD’s retinal degeneration. Studies prove that placing stem cells into damaged retinas helps. This action replaces dead or hurt cells, improving vision.
