• Abstract:

  Objective: To investigate the efficacy, mechanisms of action and potential benefits of repetitive low-level red-light therapy (RLRL) in controlling the onset and progression of myopia. Methods: Bibliographic review through the PubMed database, the PVO research strategy (Population or research problem, Variables and Outcome) was adopted, with the guiding question: "How does low-level repetitive red-light therapy affect the onset and the progression of myopia in different populations?". The initial search resulted in 32 articles, of which 15 were selected after applying inclusion and exclusion criteria. Review: It is demonstrated that RLRL presents promising results in controlling myopia, delaying its progression without generating significant adverse effects. Red light stimulates the release of dopamine by the retina, regulating the axial growth of the eye and influencing the pathophysiological processes of myopia. Final Considerations: The importance of additional research into the effectiveness of RLRL in different age groups and severities of myopia, as well as its long-term effects, is highlighted. Despite the promising results, more studies are needed to optimize its clinical application and ensure consistent and safe results for patients.
