Potassium balance and glaucoma

Retinal ganglion cells (RGCs) make up the optic nerve. When RGCs degenerate due to elevated intraocular pressure caused by glaucoma, vision is lost. Cells surrounding RGCs called Müller glia maintain a healthy ionic environment through a process called potassium siphoning, where Müller glia remove excess potassium ions through potassium channels. These glial potassium channels, such as Kir and K2P, are […]
