Age-related macular degeneration, often abbreviated as AMD, is one of the leading causes of vision loss among older adults worldwide. In Asia, where populations are ageing rapidly, its impact is particularly profound. For many, the disease quietly erodes central vision, making everyday activities such as reading, driving, and recognising faces increasingly difficult. Against this backdrop, the Translational Asian Age-related Macular Degeneration Programme, or TAAP for short, has emerged as a bold and ambitious effort to confront the disease head-on. Now in its second phase, TAAP-2 represents a significant evolution in both scientific scope and clinical ambition.

Light is something we encounter every day, so familiar that it rarely inspires a second thought. Yet beneath its apparent simplicity lies a remarkable complexity. Light can carry information in its brightness and color, but also in its polarization and phase, subtle properties that describe how its waves oscillate and interact. For decades, these hidden dimensions of light have remained largely untapped in medicine. Now, a growing body of research is beginning to reveal their extraordinary potential.
