[Age related macular degeneration]

Area of Science:

• Ophthalmology
• Genetics
• Gerontology

Context:

• Age-related macular degeneration (ARMD) is a primary cause of vision loss in individuals over 50.
• It results from a complex interplay of genetic and environmental factors.
• ARMD significantly impacts public health, particularly in Western countries.

Purpose:

• To provide an overview of age-related macular degeneration (ARMD), its classification, and current management strategies.
• To highlight the diagnostic importance of optical coherence tomography (OCT).
• To discuss treatment advancements and challenges for both wet and dry forms of ARMD.

Summary:

• ARMD presents as dry (atrophic) or wet (neovascular) forms, with the latter characterized by choroidal neovascularization leading to rapid vision decline.
• Diagnosis and monitoring rely heavily on optical coherence tomography (OCT).
• Wet ARMD treatment has advanced with anti-VEGF therapies (e.g., ranibizumab, bevacizumab) via intravitreal injections, requiring long-term follow-up.
• Dry ARMD currently has no effective treatment, and management focuses on nutritional supplements (AREDS) and rehabilitation for severe vision loss.

Impact:

• Advances in anti-VEGF therapy have improved outcomes for wet ARMD patients.
• The lack of effective treatments for dry ARMD underscores the need for further research.
• Rehabilitation and support are crucial for patients with significant visual impairment due to ARMD.
