Age-related Macular Degeneration (AMD): A Disease Affecting Central Vision

Age-related macular degeneration (AMD) is a disease that affects a person's central vision, leading to severe loss of central vision. This condition can cause significant visual impairment and is primarily an age-related retinal condition.

• Types of AMD: There are two types of macular degeneration — wet and dry. 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.
• Age Affected: AMD mostly affects those older than 50, making it a leading cause of vision loss in Americans 60 and older.

Causes and Symptoms

AMD can result from a combination of factors, including:

• Gradual deterioration of the macula as retinal cells die off and are not renewed (dry AMD)
• Breakdown of cells in the center of the retina (wet AMD)

Symptoms may include:

• Blurred vision
• Distorted or dim objects in the central part of your vision
• Faded colors

Early 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. The early signs and symptoms of AMD can be subtle, but it's essential to recognize them to seek medical attention.

Common Early Symptoms:

• Loss of Central Vision: One of the earliest signs of AMD is a loss of central vision, making it difficult to see details straight ahead [2].
• Blurred or Distorted Area in Vision: The first symptom is often a blurred or distorted area in your vision, which can be mistaken for other eye problems [4].
• Reduced Central Vision: As AMD progresses, you might experience reduced central vision in one or both eyes [3].

Other Possible Symptoms:

• Visual Distortions: Straight lines may appear bent or wavy.
• Gaps or Dark Spots: Gaps or dark spots (like a smudge on glasses) may appear in your vision, especially first thing in the morning.
• Colors Can Fade: Colors can fade or become less vibrant.

Important Note:

It's crucial to consult an eye care professional if you experience any of these symptoms. Early detection and treatment can significantly improve outcomes for AMD patients [5].

Diagnostic Tests for Age-related Macular Degeneration (AMD)

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

• Eye Examination: A comprehensive eye examination is usually the first step in diagnosing AMD. The doctor will ask about your symptoms, past eye problems, and other health conditions [1].
• Visual Acuity Test: Your doctor will check for AMD by testing your vision using a visual acuity card [6]. This test measures how well you can see objects at a distance.
• Retinal Examination: A retinal examination is also used to diagnose AMD. The doctor will examine the retina, a layer of tissue at the back of your eye that processes light [5].
• Imaging Tests: Imaging tests such as Fundus Fluorescein Angiography (FFA), Optical Coherence Tomography (OCT), and Fundus Autofluorescence Imaging (AF) may be used to confirm a diagnosis of AMD [7, 8].

These diagnostic tests can help your doctor determine the type and severity of AMD you have. If you are diagnosed with wet AMD, your doctor may also use imaging tests to detect leaking blood vessels.

Treatment Options for 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. While there are no cures for AMD, various treatment options can help manage the disease and improve vision.

Medications

Several medications have been approved to treat wet AMD, which is characterized by abnormal blood vessel growth under the retina. These include:

• Aflibercept (Eylea)
• Ranibizumab (Lucentis)
• Faricimab (Vabysmo) [5]
• Bevacizumab (Avastin)
• Brolucizumab (Beovu)

These medications work by blocking the production of vascular endothelial growth factor (VEGF), a protein that promotes blood vessel growth. By inhibiting VEGF, these drugs can help reduce fluid buildup and slow disease progression.

Other Treatment Options

In addition to medications, other treatment options for wet AMD include:

• Photodynamic therapy [6], which uses a light-sensitive drug to damage abnormal blood vessels
• Laser surgery, which can be used to treat specific areas of the retina

It's essential to note that these treatments are not cures and may need to be repeated over time. A healthcare professional can help determine the best course of treatment for an individual with AMD.

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 genetic conditions that can affect the macula and mimic 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 is a condition 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 choroid and may be mistaken for AMD [2].
• Choroidal Neovascularization (CNV): This is a condition characterized by abnormal blood vessel growth 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 rule out other conditions.
