RPE stands for?

• A. Retinal Pigment Endothelium
• B. Retinal Pigment Epithelium Layer
• C. Retinal Pigment Epithelium Cells
• D. Retinal Pigment Epithelium

Answer: (D)

RPE stands for Retinal Pigment Epithelium. This is the pigmented, single-cell-thick layer that sits between the photoreceptors and the choroid, and it plays a key supporting role for vision by managing the outer retina’s health, refreshing the visual pigments, and phagocytosing shed photoreceptor debris. Using “endothelium” would misidentify the tissue, since endothelium refers to the inner lining of blood vessels, not this retinal layer. Saying “layer” or “cells” isn’t the standard naming for this tissue, and the concise, widely used term is Retinal Pigment Epithelium. In OCT images, it appears as a distinct, reflective band just above the choroid, highlighting its importance in retinal structure and pathology.
