Bruch membrane function
Bruch's membrane is the innermost layer of the choroid of the eye. It is also called the vitreous lamina or Membrane vitriae, because of its glassy microscopic appearance. It is 2–4 μm thick. See more Bruch's membrane consists of five layers (from inside to outside): 1. the basement membrane of the retinal pigment epithelium 2. the inner collagenous zone See more Bruch's membrane was named after the German anatomist Karl Wilhelm Ludwig Bruch. See more Bruch's membrane is present by midterm in fetal development as an elastic sheet. See more Bruch's membrane thickens with age, slowing the transport of metabolites. This may lead to the formation of drusen in age-related macular degeneration See more • Pictures at National Eye Institute See more WebMar 1, 2024 · Bruch’s membrane acts as a physical and biochemical barrier for both molecules and cells between the retina/RPE and the choroid, as reservoir of anti-angiogenic factors and as scaffold for the ...
