Definitions for "RETINAL PIGMENT EPITHELIUM"
(RPE): Layer of cells behind the sensory retina. Performs many metabolic tasks for the neural retina.
a very thin, pigmented cell layer directly beneath the retina. It provides nutrients and various survival factors to the photoreceptors and carries waste products away. A disease causing mutation expressed in the RPE causes congenital stationary night blindness.
Pigment cell layer just outside the retina that nourishes retinal visual cells; is firmly attached to underlying choroid and overlying retinal visual cells- composed of one layer of cells that are densely packed with pigment granules.
