Fundus neovascularization is a significant cause of ocular diseases, mainly including retinal neovascularization and choroidal neovascularization. Anti-vascular endothelial growth factor therapy, though effective, has limitations such as a short half-life, non-responsiveness, and drug resistance. 6-Phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3 (PFKFB3), a key regulator of glycolysis, affects the generation of pathological blood vessels by modulating the metabolism of vascular endothelial cells. Small molecule inhibitors targeting PFKFB3 protein have been confirmed in animal and cell models to significantly inhibit pathological angiogenesis, showing good therapeutic potential. However, most of them are still in the preclinical research stage. In the future, it is necessary to further investigate the mechanism of PFKFB3, optimize the specificity and safety of the inhibitors, and explore the effects of combining them with existing therapies, so as to provide new strategies for the treatment of fundus neovascular diseases.
