NCIt related terms : RETINAL PIGMENTED EPITHELIAL LAYER;
NCIt definition : A continuous, insulating monolayer of cuboidal/columnar epithelium which extends from
the margins of the optic nerve head to the ora serrata where it is continuous with
the pigment epithelium of the pars plana. This cell layer has many physical, optical,
metabolic/biochemical and transport functions which play a critical role in the normal
visual process, including acting as a selective filter to determine what nutrients
reach the retina from the choroid.;
Alternative definition : CDISC: A continuous, insulating monolayer of cuboidal/columnar epithelium which extends
from the margins of the optic nerve head to the ora serrata where it is continuous
with the pigment epithelium of the pars plana. (NCI);
