Aqueous humor level of sCD44 in patients with degenerative myopia and primary open-angle glaucoma

摘要

BackgroundThe transmembrane glycoprotein CD44 is a major hyaluronan cell surface receptor widely distributed in eye tissues and fluids. The shed ectodomain of CD44 is termed soluble CD44 and is toxic to human retinal ganglion cells in cell culture. The purpose of this study was to investigate the concentration of sCD44 in the aqueous humor (AH) of normal subjects, patients with primary open-angle glaucoma, and patients with degenerative myopia but without glaucoma, to determine if the molecule might serve as a protein marker of glaucoma.
