Abstract:The structure of the pigment epithelium at the ora serrata is examined in 10 human eyes aged from 31 to 90 years. The cells of the pigment epithelium show a different construction depending on their position relative to the ora. Directly at the ora serrata, in the cohesion band, the cells are higher and contain more pigment granula than those which are situated in a central region. In this sector we sometimes find overlapping of cells, which feigns two layers of epithelium. There are clearly fewer basal foldin… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
