Which acronym stands for retinal pigment epithelium?

Which acronym stands for retinal pigment epithelium?

• A. RPE
• B. RNFL
• C. SD-OCT
• D. SLO

Answer: (A)

Retinal pigment epithelium is a pigmented cell layer that lies under the neural retina and plays a crucial supporting role for photoreceptors, including debris processing and forming the outer blood-retina barrier. The acronym that names this tissue is RPE, with R for retinal, P for pigment, and E for epithelium. The other terms refer to different things: retinal nerve fiber layer is a layer of nerve fibers in the inner retina, while spectral-domain OCT and scanning laser ophthalmoscopy are imaging technologies used to visualize retinal structure, not the tissue itself.
