Abstract:Corneal neovascularization(CNV)is one of the most important causes that affecting corneal transparency, and it is a high risk factor of allogeneic corneal graft rejection. It has become a research focus for the regulation of CNV. microRNAs are a class of endogenous non-protein-coding micromolecule RNAs which play a critical role in regulating a series of life process. Researches in recent years show a close correlation between microRNA and CNV. In this article we reviewed the recent advances in these researches.
