Interleukin-18 is an inactive precursor which lacks a signal peptide, it has a role in regulating retinal pathological angiogenesis. It also inhibits experimental choroidal neovascularization (CNV) via interferon-γand thrombospondin-1. Currently little is known about its mechanisms of inhibition for CNV, may be speculated to be due to effects of anti-angiogenesis, down-regulates vascular permeability and lower vascular endothelial growth factor (VEGF) levels via directly acting on the vascular endothelial cell and epithelial cells. Exogenous administration of mature recombinant interleukin-18 has no adverse effect on retinal pigment epithelial cell viability. In addition, the anti-VEGF role of interleukin-18 is tested to be safe and effective for humans. Interleukin-18 alone or in combination with anti-VEGF shows to be a good prospect for improving the prognosis of experimental CNV. However, more large clinical studies are required to confirm the exact efficacy of interleukin-18 for CNV.
