Glaucoma-associated corneal endothelial cell damage: A review
One area of research interest is how medically-treated glau-coma affects the corneal endothelium. Patients with glau-coma often remain on long-term therapy with varyingnumbers of pressure-lowering glaucoma drops. Thesemedications have been studied extensively and have beenshown to cause molecular changes in experimental models aswill be discussed in the following section; however, glaucomamedications have not been linked directly with endothelialcell loss.

Endothelium - The endothelium is the extremely thin, innermost layer of the cornea. Endothelial cells are essential in keeping the cornea clear. Normally, fluid leaks slowly from inside the eye into the middle corneal layer (stroma). The endothelium's primary task is to pump this excess fluid out of the stroma. Without this pumping action, the
