Core Tip
Core tip: Loss of corneal endothelial cells have been reported in primary open-angle glaucoma (POAG) patients. Elevated intraocular pressure, cell toxicity after long-term exposure to preservatives and glaucoma surgery have been reported to be possible mechanisms for endothelial damage. In this study, we aimed to document the corneal endothelial changes and their correlations with mean intraocular pressure between POAG patients and normal controls. We found that the corneal endothelial cell density in POAG patients is decreased and the average endothelial cell area is increased compared with those in healthy controls. High intraocular pressure and anti-glaucoma medication in POAG may be the main causes of corneal endothelial cell damage.
