Abstract: The present invention is directed to an RNAi-inducing agent capable of reducing and/or inhibiting the expression of proteins associated with the tight junction complex joining Schlemm's canal endothelial cells (SCEC) in the eye of a subject for use in the prevention and/or treatment of glaucoma. Specifically, the RNAi-inducing agent is capable of reducing and/or inhibiting the expression of proteins expressed in the tight junction complex or supporting the tight junction complex joining Schlemm's canal endothelial cells (SCEC) in the eye of a subject for use in the prevention and/or treatment of glaucoma. Methods using this RNAi-inducing agent are also contemplated.
