Introduction to Age-related Macular Degeneration and Biomarkers

Globally, age-related macular degeneration affects over 196 million people, posing irreversible threats to central vision. This condition damages the retinal pigment epithelium, progressively impairing tasks like reading and facial recognition. By 2040, cases could double as populations age, making early detection critical for preserving visual function.

Vision’s Silent Threat

AMD silently erodes central vision through two mechanisms: cellular waste accumulation (drusen) and blood vessel leakage. A 2023 systematic review found patients with intermediate-stage AMD face 3.2x higher vision loss risk within five years. Functional tests like dark adaptometry measure night vision decline – often the first warning sign.

Predictive Power of Retinal Clues

Advanced imaging reveals critical risk indicators. OCT scans detect disease progression markers like drusen volume exceeding 0.03 mm³, which correlates with 89% progression accuracy in Phase III trials. Combined with color fundus photography, these tools create actionable timelines for intervention.

Current guidelines recommend annual screenings for high-risk groups, leveraging these biomarkers to customize treatment plans. As research evolves, combining structural and functional data offers unprecedented precision in blindness prevention.
