A novel heat-based treatment developed by researchers at Aalto University offers the first potential intervention for dry age-related macular degeneration (AMD), a condition affecting millions worldwide. The experimental approach uses precisely controlled near-infrared light to deliver thermal energy to retinal cells, stimulating the body’s natural cellular cleaning process known as autophagy. Unlike existing treatments that address damage after it occurs, this preventive method targets the underlying cellular breakdown before vision loss becomes irreversible. Early laboratory studies demonstrate that the therapy can activate these cellular repair mechanisms without causing thermal damage to surrounding tissue. The technique addresses a critical gap in AMD management, as dry AMD accounts for 90% of all cases and currently lacks effective treatment options. Researchers emphasize that success depends on maintaining precise temperature control within a narrow therapeutic window. This breakthrough represents significant progress toward preventing vision loss in millions of AMD patients globally.
