- EMAPA:37450 (MA:th)
A transparent, nearly structureless innermost layer of the choroid in contact with the pigmented layer of the retina.
Bruch's membrane is present by midterm in fetal development as an elastic sheet.

basal lamina of choroid
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; 3. a central band of elastic fibers; 4. the outer collagenous zone; 5. the basement membrane of the choriocapillaris. The retinal pigment epithelium transports metabolic waste from the photoreceptors across Bruch's membrane to the choroid[WP]
