Profiling the Ocular Landscape of sEVs miRNAs: Mechanisms and Applications

In this review, we comprehensively discuss the application of sEVs miRNAs in ophthalmic diseases by examining their basic characteristics and clinical application potential. Initially, we provide an overview of sEVs, including their definition, source, and functions, while particularly highlighting the importance of miRNAs contained in sEVs and its prospects in the treatment of ocular diseases. Subsequently, the structure and composition of sEVs as well as the biological functions of their encapsulated miRNAs, which expands the current knowledge about their roles in ophthalmic physiology and pathology. In addition, the functions of sEVs miRNAs in the growth of ocular tissues, ocular tissue homeostasis, and common eye diseases such as glaucoma, age-related macular degeneration, and diabetic retinopathy, are discussed. The application potential of sEVs miRNAs as diagnostic biomarkers and drug delivery systems for ophthalmic conditions and therapeutic value in diverse eye diseases are explored. Finally, the current challenges affecting research in this field are outlined to provide a basis that guide future utilization of sEVs miRNAs in ophthalmic disease research and clinical management of diverse ophthalmological conditions.
