Endothelial Nitric Oxide Synthase Gene Variants and Primary Open-Angle Glaucoma

Abstract
The nitric oxide synthase 3 (NOS3) enzyme catalyzes the production of nitric oxide, which influences the tone of luminal structures with smooth muscle.1 NOS3 is of interest in glaucoma because this isoform is in the human outflow pathway2 and in the ocular endothelial cells in the vasculature for retinal ganglion cells.3
