Age-related Macular Degeneration (AMD) Description

Age-related macular degeneration (AMD) is a chronic but painless disease [9]. It affects a special layer of cells in the eye called the retinal pigment epithelium, which plays a crucial role in maintaining the health and function of the retina.

Key Points:

• AMD is a gradual process that can lead to significant central visual impairment.
• The disease primarily affects older adults, with most cases occurring after the age of 50 [5].
• There are two types of AMD: dry (atrophic) and wet (exudative), each with distinct characteristics and symptoms.

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. The symptoms of AMD can vary from person to person, but here are some common signs and symptoms:

• Blurred or distorted vision: A person may notice that their central vision is blurry or distorted, making it difficult to read, watch TV, or perform other daily activities [5].
• Loss of central vision: As the condition progresses, a person may experience a loss of central vision in one or both eyes, making it hard to see details straight ahead [2].
• Visual distortions: Straight lines may appear bent or wavy, and colors may fade or become less vibrant [3][7].
• Difficulty seeing in low light: People with AMD may find that they need brighter light to see clearly, as their eyes have trouble adjusting to dim lighting conditions [3].
• Gaps or dark spots: In some cases, people may notice gaps or dark spots (like a smudge on glasses) in their vision, especially first thing in the morning [6].

It's essential to note that AMD can progress slowly over time, and symptoms may not be immediately apparent. If you're experiencing any of these signs and symptoms, it's crucial to consult an eye care professional for proper diagnosis and treatment.

Diagnostic Tests for Age-related Macular Degeneration

Age-related macular degeneration (AMD) can be diagnosed using various tests that help doctors assess the condition and monitor its progression. Here are some diagnostic tests used to detect AMD:

• Visual Acuity Test: This test measures a person's ability to see objects clearly at a distance. It is often used as an initial screening tool for AMD.
• Dilated Eye Exam: During this exam, the eyes are dilated with eye drops to allow the doctor to examine the retina and macula more closely.
• Fluorescein Angiography (FA): This test uses a special dye to highlight blood vessels in the retina. It can help doctors identify areas of damage or abnormal growth.
• Optical Coherence Tomography (OCT): OCT is a non-invasive imaging test that takes high-resolution pictures of the retina and macula. It can help doctors detect changes in the retina and monitor disease progression.
• Multifocal ERG: This test measures the electrical activity of the retina to assess its function.

These tests are often used in combination with each other to diagnose AMD and monitor its progression. Early detection is crucial for effective management and treatment of the condition.

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's no cure for AMD, various treatment options are available to slow down its progression and prevent serious loss of vision.

Medications

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

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

These medications, known as anti-vascular endothelial growth factor (anti-VEGF) agents, work by blocking the production of vascular endothelial growth factor (VEGF), a protein that promotes blood vessel growth in the eye. By inhibiting VEGF, these medications can help slow down or stop the progression of wet AMD.

Other Treatment Options

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

• Photodynamic therapy (PDT)
• Laser surgery

These treatments aim to reduce the abnormal blood vessel growth in the eye and prevent further vision loss.

Dry AMD Treatment

While there are no FDA-approved treatments specifically for dry AMD, researchers are exploring various options, including Syfovre, a treatment recently approved for use in the US. However, more research is needed to confirm its effectiveness.

Differential Diagnoses for Age-related Macular Degeneration (AMD)

Age-related macular degeneration (AMD) is a complex condition that can be challenging to diagnose, particularly in its early stages. Here are some differential diagnoses that may 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.
• Angioid streaks: These are breaks in Bruch's membrane that can cause vision loss and are often associated with systemic conditions such as pseudoxanthoma elasticum.
• Central Serous Chorioretinopathy (CSCR): This is a condition characterized by the accumulation of fluid under the retina, which can cause visual disturbances and is often associated with stress or hormonal changes.
• Choroidal Melanoma: A type of eye cancer that can affect the choroid layer of the eye and cause vision loss.
• Choroidal Neovascularization (CNV): This is a condition characterized by the growth of new blood vessels under the retina, which can cause vision loss and is often associated with AMD.

According to [9], Age-related macular degeneration (AMD) is a leading cause of vision loss in the elderly, highlighting the need for early and accurate detection. A thorough differential diagnosis is essential to rule out these conditions and ensure that patients receive the correct treatment.
