Compared to treated eyes without glaucoma or glaucoma suspect, treated eyes with glaucoma had lower EC density (3289 vs 3783 cells/mm 2 , p = 0.03) and treated eyes with glaucoma suspect had greater mean corneal thickness (660 vs 612 μm, p = 0.0036).

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.

The primary pathway of drug permeation from the tear fluid to the anterior chamber of the eye is via the trans-corneal route.

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
