The retinal pigmented epithelium (RPE), the cellular monolayer located between the neuroretina and the highly vascularized choroid, from which it is separated by Bruch's membrane (BrM), has a critical role in human vision and performs essential functions throughout life for maintaining the retinal homeostasis. The RPE is particularly susceptible to aging, sustaining significant morphologic and physiologic changes.
