Choroidal neovascularization(CNV)is the ultimate pathological manifestation of various ocular diseases. Its pathogenesis is extremely complex and involves multiple cells, cytokines, and signaling pathways. MicroRNA(miRNA), as a kind of small biological molecules, is a non-coding RNA composed of 22 nucleotides that regulates gene expression by degrading or inhibiting mRNA translation of target genes. Having been increasingly studied and their involvement in the development of various diseases through miRNA-mediated signaling pathways have been revealed. In the field of ophthalmology, miRNA target specific protein genes through various signaling pathways to promote or inhibit CNV. Therefore, revealing the role and mechanism of miRNA in the pathogenesis of CNV is an important direction of future research on the pathogenesis of CNV. This article aims to review on phosphatidylinositol 3 kinase- protein kinase B(PI3K-Akt), transforming growth factor-beta(TGF-β), nuclear factor-kappa B(NF-κB), Notch and Wnt signaling pathways in miRNA regulation of CNV, providing new insights into the pathogenesis of CNV and targeted therapy for CNV.
