With rapid advances in clinical applications, numerous studies have confirmed its unique potential in slowing axial elongation in children and adolescents. However, the underlying mechanisms of monochromatic light remain inconclusive within the academic community. This review summarizes recent progress in animal studies investigating the effects of monochromatic light characteristics—including wavelength, exposure duration, light intensity, and exposure initiation period—as well as related circadian rhythm disturbances on ocular growth and refractive development. Current evidence suggests that monochromatic light may regulate eye growth through mechanisms such as modulation of retinal cone signaling, dopamine metabolism, and choroidal thickness alterations. In clinical research, investigations of monochromatic light have primarily focused on repeated low-level red light (RLRL) therapy. As an emerging intervention, RLRL has demonstrated potential in slowing myopia progression. However, its long-term efficacy and safety remain topics of ongoing debate. This review synthesizes current findings from both animal and human studies, explores the underlying biological mechanisms, and discusses the challenges associated with the clinical application of RLRL therapy.</div></div>","PeriodicalId":20141,"journal":{"name":"Photodiagnosis and Photodynamic Therapy","volume":"55 ","pages":"Article 104735"},"PeriodicalIF":2.6,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144719298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite significant advancements in PDT administration, resistance in certain tumors typically limits an increase in survival rates. One strategy to improve PDT outcomes is using DNA repair inhibitors to disrupt the DNA repair mechanism. DNA repair inhibitors are compounds that interfere with the cellular mechanisms responsible for repairing damaged DNA. These inhibitors can be applied to cancer treatment that they make tumor cells more sensitive to other forms of treatments, including radiation, chemotherapy and PDT. These agents can enhance the effectiveness of treatments <em>via</em> preventing DNA repair in cancer cells. Moreover, DNA repair inhibitors have the ability to overcome treatment resistance after PDT. In this review, we highlight the critical responses to PDT-induced DNA damage and the progress made in blocking DNA repair mechanisms through clinical and preclinical studies using nanotechnology or combination therapy. Critically, we highlighted the role of nanomedicine in PDT by offering a platform for the simultaneous delivery of DNA repair inhibitors and photosensitizer (PS). This strategy lead to broaden the therapeutic window for drug delivery and overcoming PDT resistance. Finally, latest findings and studies have been gathered and some suggestions were presented for future studies in this area.
