Retinoblastoma(RB)represents the most common primary intraocular malignant tumor in infants and young children, posing a severe threat to the visual acuity and life of affected patients. Clinically, it is categorized into hereditary and non-hereditary subtypes. Mounting evidence indicates that RB cells most likely originate from cone photoreceptor precursor cells, and the tumorigenesis is closely associated with the inactivation of the RB1 gene. Beyond RB1, a growing list of genes including MYCN, TP53 and PRMT1 have been implicated in the initiation and progression of RB. Concurrently, the dysregulation of multiple signaling pathways such as RB/E2F, WNT, and PI3K/AKT synergistically drives the survival, proliferation, invasion, and metastasis of RB tumor cells. The therapeutic paradigm for RB has undergone a dramatic shift from the conventional enucleation-dominated approach to personalized multimodal therapies that prioritize globe salvage and visual preservation, encompassing local therapies, chemotherapy and radiotherapy. Moreover, novel therapeutic modalities including targeted therapy, immunotherapy and gene therapy are currently under active preclinical and clinical investigation. In recent years, long non-coding RNAs(lncRNAs), as pivotal regulators of genetic expression, have attracted increasing attention for their critical roles in RB oncogenesis and progression. These molecules hold great promise to serve as novel diagnostic biomarkers and offer innovative insights and strategies for RB treatment. This review summarizes the latest research advances in the aforementioned aspects of retinoblastoma.

Extracellular vesicles(EVs)are nanoscale membrane vesicles released by cells that carry bioactive molecules such as proteins and nucleic acids. They play a key role in intercellular communication. In recent years, they have shown significant potential in the diagnosis and treatment of corneal and ocular surface diseases. As diagnostic biomarkers, EVs derived from tears or other sources can reflect disease-specific characteristics, providing a basis for the early disease detection. In terms of therapy, mesenchymal stem cells(MSCs)-derived EVs deliver miRNAs to modulate inflammatory pathways, promote corneal epithelial repair, and inhibit fibrosis. Furthermore, as natural drug vehicles, EVs enable precise delivery of therapeutic agents and promote corneal wound healing. This review systematically summarizes the recent research advances in the application of EVs in the field.

In recent years, the prevalence of myopia has shown a significant upward trend characterized by earlier onset and accelerated progression rates. This epidemic not only imposes an increasing socioeconomic burden but also leads to severe vision impairment through high myopia-related complications that profoundly affect daily life. Current research on the pathogenesis of myopia primarily focuses on four mechanistic theories, including scleral remodeling, choroidal hemodynamic abnormalities, dopamine synthesis and metabolism, and inflammatory responses. The advent of high-throughput sequencing technologies has revolutionized our investigative approaches, enabling deeper exploration into myopia development through multi-omics strategies encompassing genomics, proteomics, and metabolomics. These cutting-edge methodologies have provided novel insights for myopia prevention and control, while simultaneously identifying potential therapeutic targets for precision intervention. This review focuses on summarizing the aforementioned research findings.
