RNA interference is an important discovery in the field of biology in recent years, which is a gene silencing phenomena of specific sequences induced by double-stranded RNA. RNAi technology becomes perfect and mature increasingly, and has been gradually applied in functional genomics, regulatory mechanisms of gene expression research areas.As an effective tool, RNAi technology in gene therapy of eye disease has also made great progress.This paper briefly reviews the current researches of RNAi technology adopting in corneal endolthelial cells injury and therapies of cataract, glaucoma, neovascular diseases and proliferative vitreoretinopathy.
