[De Silva Sandun (2026); evidence level 4] - Oxidative stress, chronic inflammation, mitochondrial dysfunction, dysregulated angiogenesis and metabolic imbalance are highly associated with the molecular-level pathogenesis of these ocular diseases. [De Silva Sandun (2026); evidence level 4] - Furthermore, bioavailability and therapeutic potential are increased by synergistic interactions among bioactives in whole extracts and improvements in delivery systems (e.g., nano-formulations). [De Silva Sandun (2026); evidence level 4] - 1 2 2 3 4 5 6 Visual impairment is a major global health problem with an increasing prevalence due to population ageing, higher incidence of metabolic diseases such as diabetes, and prolonged exposure to digital devices.
