Age-related Macular Degeneration (AMD)

Age-related macular degeneration (AMD) is a disease that affects a person's central vision [1]. It can result in severe loss of central vision, making everyday activities such as reading, driving, and recognizing faces challenging.

There are two types of AMD: dry and wet. Dry AMD is a gradual deterioration of the macula as the retinal cells die off and are not renewed [8]. Wet AMD, on the other hand, is characterized by abnormal blood vessel growth under the retina, which can cause rapid vision loss.

The most common symptom of dry AMD is blurred vision, with objects in the center part of your vision looking distorted and dim, and colors appearing faded [4].

AMD primarily affects people over 50 years old, making it a leading cause of vision loss in Americans 60 and older [6]. It is essential to be aware of the symptoms and seek medical attention if you experience any changes in your central vision.

Key Facts:

• AMD affects central vision
• Two types: dry and wet
• Dry AMD causes gradual vision loss
• Wet AMD causes rapid vision loss
• Most common symptom: blurred vision
• Affects people over 50 years old

Common Signs and Symptoms of Age-related Macular Degeneration (AMD)

Age-related macular degeneration (AMD) is a condition that affects the macula, the part of the retina responsible for central vision. As people age, they may experience various symptoms that can indicate the presence of AMD.

• Visual Distortions: Straight lines may appear bent or wavy [3].
• Reduced Central Vision: The ability to see fine details straight ahead may be impaired [2].
• Need for Brighter Light: People with AMD may need brighter light to read or perform other tasks that require good vision [3].
• Blurred or Distorted Area in Vision: A person may notice a blurred or distorted area in their vision, which can worsen over time [4].
• Loss of Central Vision: Early signs of AMD can include loss of central vision, making it difficult to read or perform tasks that require good vision [5].
• Gaps or Dark Spots: Gaps or dark spots may appear in the vision, especially first thing in the morning [6].
• Colors Can Fade: Colors may appear less vibrant or fade over time [6].
• Dark, Blurry Areas: Dark, blurry areas can appear in the center of the vision, making it difficult to see fine details [7].

It's essential to note that these symptoms can be similar to those experienced by people with other eye conditions. If you're experiencing any of these symptoms, consult an eye care professional for a proper diagnosis and treatment plan.

Diagnostic Tests for Age-related Macular Degeneration

Age-related macular degeneration (AMD) can be diagnosed through various tests and exams. Here are some of the diagnostic tests used to detect AMD:

• Optical Coherence Tomography (OCT): This test uses low-coherence interferometry to capture high-resolution images of the retina, allowing doctors to visualize the macula and detect any abnormalities [1].
• Retinal Photography: A retinal photography exam can help identify changes in the center of your vision, which is common in AMD [10].
• Angiography: This test helps identify changes in blood flow or leaking fluid, which is common in wet age-related macular degeneration [10].
• Pupil Dilation: Pupil dilation allows doctors to get a better view of the retina and detect any abnormalities [8].
• Amsler Grid Eye Test: The Amsler grid can help detect early signs of retinal disease and monitor changes in vision after an AMD diagnosis [5].

These tests are typically performed by an eye doctor during a comprehensive eye exam. If you're experiencing symptoms of AMD, it's essential to consult with an eye care professional for proper diagnosis and treatment.

Treatment Options for Age-related Macular Degeneration (AMD)

According to various studies and medical sources, there are several treatment options available for age-related macular degeneration (AMD). Here are some of the most common ones:

• Anti-VEGF agents: These medications, such as Lucentis (ranibizumab), Eylea (aflibercept), Beovu (brolucizumab), and Vabysmo (faricimab-svoa), are injected directly into the eye to stop the growth of abnormal blood vessels that can cause vision loss.
• Pegcetacoplan: This is a new drug approved for treating dry AMD, which has been shown to slow down the progression of the disease.

Common Medications Used in Treating Wet AMD

Some of the most commonly used medications in treating wet AMD include:

• Aflibercept (Eylea)
• Ranibizumab (Lucentis)
• Bevacizumab (Avastin)
• Brolucizumab (Beovu)
• Faricimab-svoa (Vabysmo)

Side Effects and Risks

While these medications can be effective in treating wet AMD, they also carry some risks and side effects, including:

• Eye infection
• Inflammation of the eye
• Increased risk of bleeding

It's essential to discuss these potential risks with your doctor before starting any treatment.

Differential Diagnoses for Age-related Macular Degeneration (AMD)

Age-related macular degeneration (AMD) is a complex condition that can be challenging to diagnose, especially in its early stages. Here are some differential diagnoses that should be considered:

• Other genetic macular diseases: Stargardt disease, Best disease, and pattern dystrophy are all conditions that affect the macula and can present similarly to AMD [1].
• Angioid streaks: These are breaks in Bruch's membrane that can cause vision loss and may be mistaken for AMD [2].
• Central Serous Chorioretinopathy (CSCR): This condition is characterized by fluid accumulation under the retina, which can cause visual disturbances similar to those seen in AMD [2].
• Choroidal Melanoma: A type of eye cancer that can affect the macula and may be mistaken for AMD [3].
• Choroidal Neovascularization (CNV): This is a condition where new blood vessels grow under the retina, which can cause vision loss similar to AMD [2].

It's essential to consider these differential diagnoses when evaluating patients with suspected AMD. A thorough medical history, physical examination, and diagnostic tests such as optical coherence tomography (OCT) and fluorescein angiography may be necessary to confirm a diagnosis of AMD.
