Abstract: Ocular diseases represent a major and increasing public health concern. Although current treatment options are available, the management of complex cases, such as corneal diseases, diabetic retinopathy, glaucoma, age-related macular degeneration, and uveitis, remains inadequate. Recent studies have demonstrated that mesenchymal stem cell-derived exosomes (MSC-Exos), obtained from bone marrow, adipose tissue, and umbilical cord, have emerged as a promising cell-free therapeutic platform for various ocular diseases. These nanovesicles can be delivered via systems such as topical eye drops and intravitreal injection, targeting ocular tissues to exert anti-inflammatory, anti-apoptotic, and tissue-repairing effects. This review systematically synthesizes recent advances and the molecular mechanisms underlying the use of MSC-Exos in treating ocular diseases. Moreover, it provides an in-depth discussion of the challenges in the clinical application of MSC-Exos in ophthalmology, including standardized production, dosage optimization, delivery system improvement, and targeting enhancement, and proposes engineered targeting strategies based on surface modification and carrier optimization. Overall, this work establishes a rigorous framework for advancing MSC-Exos from experimental models to clinical implementation, offering novel therapeutic strategies through these innovative biopharmaceuticals for previously untreatable ocular conditions.
