Lately, we have seen many commercials on cable, Netflix, and Hulu, specifically for treating Age-Related Macular Degeneration (AMD). We wondered how many people know what AMD is. We’re here to help answer that question. AMD, or age-related macular degeneration, is a degenerative disease that damages the macula, a small area at the back of the eye, crucial for central vision.
There are two main types of AMD: dry and wet.
- Dry AMD is the most common type, characterized by the gradual thinning of the macula.
- Wet AMD is less common but progresses more rapidly. It involves the growth of abnormal blood vessels under the macula that can leak fluid and cause rapid vision loss.
Risk Factors for AMD
Several factors can increase your risk of developing AMD, including:
- Age: The risk of AMD increases with age, particularly after 50.
- Genetics: A family history of AMD can significantly increase your risk.
- Smoking: Smoking is a significant risk factor for AMD and can accelerate its progression.
- High blood pressure: Uncontrolled high blood pressure can damage blood vessels in the eyes.
- Diet: A diet high in saturated fats and low in antioxidants may increase the risk of AMD.
- Obesity: Being overweight or obese can contribute to AMD.
- Sunlight exposure: Excessive exposure to sunlight, especially without adequate eye protection, can damage the macula.
Early Signs and Symptoms of AMD
Early signs of AMD may include:
- Blurred central vision
- Straight lines appearing wavy or distorted
- Difficulty recognizing faces or reading
- A dark spot in the center of your field of vision
If you experience any of these symptoms, it’s essential to see an eye doctor immediately for an evaluation.
Regular Eye Exams for AMD Screening
Regular eye exams are crucial for detecting AMD early, especially for individuals over the age of 50 or those with a family history of the condition. During an eye exam, your doctor will use special equipment to examine the macula and look for signs of AMD.
Early Detection is key: At Medical Eye Center, we encourage all patients to get the Optomap scan, a more extensive retinal imaging scan that can map the back of the eye with a 200° radius. This scan can help with the early detection of many conditions, not just AMD.
Often, we may also use other tests such as Fluorescein angiography or Indocyanine green angiography. During both tests, your eye doctor injects a dye into a vein in your arm. The dye travels to and highlights the blood vessels in your eye. A special camera takes several pictures as the dye travels through the blood vessels. The images will show if you have retinal or blood vessel changes, which are a sign of wet macular degeneration.
Lifestyle Changes to Reduce AMD Risk
While there is no guaranteed way to prevent AMD, specific lifestyle changes can help reduce your risk:
- Quit smoking: Smoking is one of the most significant risk factors for AMD.
- Maintain a healthy weight: A healthy diet and regular exercise can help you maintain a healthy weight.
- Protect your eyes from sunlight: Wear sunglasses with UV protection and a wide-brimmed hat when outdoors.
- Manage chronic conditions: If you have conditions like high blood pressure or diabetes, work with your doctor to manage them effectively.
- Consider supplements: Some studies suggest that supplements like lutein and zeaxanthin may help protect the macula. However, it’s essential to consult with your doctor before starting any new supplements.
Research from the Age-Related Eye Disease Study 2 (AREDS2) has shown benefits in a formulation that includes:
- 500 milligrams (mg) of vitamin C
- 400 international units (IU) of vitamin E
- 10 mg of lutein
- 2 mg of zeaxanthin
- 80 mg of zinc (as zinc oxide)
- 2 mg of copper (as cupric oxide)
Treatment Options for AMD
While there is no way to reverse the damage from AMD, treatment options are available to slow its progression and preserve vision.
- Dry AMD: There is currently no treatment for dry AMD. However, a healthy lifestyle can help slow its progression.
- Wet AMD: Treatment options for wet AMD include anti-VEGF injections, which can help prevent the growth of abnormal blood vessels under the macula.
For living with AMD, there are many options available, such as changing computer/digital displays, updating the lights in your home, or considering all your transportation options. For more information, check out this article: https://mayocl.in/47kiLp9
If you are concerned about AMD, it’s essential to see your eye doctor regularly for early detection and to discuss preventive measures and treatment options with an Ophthalmologist. By taking steps to protect your vision, you can help reduce your risk of AMD and maintain your quality of life.
