WebRetinal Pigment Epithelial (RPE) Tears, also known as RPE tears or rips, is a phenomenon first described in 1981 [1] in which the RPE acutely tears from itself and retracts in an area of retina usually overlying a pigment epithelial detachment (PED) at the junction of detached RPE and flat RPE, leaving the underlying Bruch's membrane and … WebJul 1, 2005 · I. INTRODUCTION. The retinal pigment epithelium (RPE) is a monolayer of pigmented cells forming a part of the blood/retina barrier (72, 372, 492, 558).The apical membrane of the RPE faces the photoreceptor outer segments ().Long apical microvilli surround the light-sensitive outer segments establishing a complex of close structural …

Its structure is very complicated, having five sublayers containing basement membranes of retinal pigment epithelium and choriocapillary endothelium, outer and inner collagenous layers, and a central elastic layer. WebBruch's membrane is a thin, acellular, five-layered ECM located between the metabolically active retinal pigment epithelium (RPE) and choriocapillaris. It thus serves as the substratum of the RPE. Nanofibrous networks closely mimic the fibrous architecture of the native inner collagenous layer of Bruch’s membrane. theater auditions
