Fine Structure of the Choroid

Abstract

Figure 48 shows radial sections of the baboon choroid. It is approximately 95 µm deep in the foveal region, but only 55 µm in the periphery (see also Fig. 6). The basal labyrinth of the pigment epithelium is at the bottom of Figure 48 beneath Bruch’s membrane (B). Two small drusen are seen at D (Fig. 48A). The choroidocapillaris (C) is embedded in a fiber system consisting of Bruch’s membrane, connecting fiber columns (FC), and an external collagen fiber layer (F). This recently discovered fiber system of the choroidocapillaris may be important for the patency of the capillary sinus (Krebs and Krebs 1990). The thickness of the choroidocapillaris decreases from 10 µm in the fovea to 7 µm in the periphery.
