Recent developments in age-related macular degeneration: a review

Area of Science:

• Ophthalmology
• Gerontology
• Medical Research

Background:

• Visual impairment in the elderly is a significant global health concern.
• Age-related macular degeneration (AMD) disproportionately affects older populations, impacting quality of life.
• The prevalence of AMD is increasing due to demographic shifts towards an aging global population.

Purpose of the Study:

• To comprehensively review the clinical and pathological features of age-related macular degeneration (AMD).
• To examine current and emerging diagnostic tools for AMD.
• To evaluate existing and investigational therapeutic strategies for both atrophic and wet AMD.

Main Methods:

• Conducted an online literature review using the PubMed database.
• Searched for relevant keywords pertaining to age-related macular degeneration.
• Limited the search to articles published from 1980 to the present day.

Main Results:

• Identified key risk factors for AMD including advanced age, smoking, diet, and family history.
• Highlighted the implicated role of genetic factors in AMD pathogenesis, though mechanisms remain under investigation.
• Described current treatments: observation and nutritional supplements for atrophic AMD, and anti-angiogenic therapies targeting choroidal neovascularization for wet AMD.

Conclusions:

• Emphasized that identifying and modifying AMD risk factors is crucial for prevention.
• Stated that anti-vascular endothelial growth factor (anti-VEGF) therapies have significantly improved outcomes for wet AMD, a leading cause of irreversible blindness.
• Acknowledged the transformative impact of anti-VEGF agents on the management of wet AMD.
