(A) Electron micrograph of a monkey's Bruch's membrane and choriocapillaris showing endothelial processes (small arrow) (final magnification 40 000) and (B) electron micrograph showing a process (small arrow) protruding through the elastic lamina of Bruch's membrane (thick arrow) (final magnification 80 000). (C) Electron micrograph in which the endothelial cell appears to have an increase in cytoplasmic organelles (small arrow) (final magnification 48 000), and (D) electron micrograph with processes displacing the basal lamina (small arrow) of the endothelial cell (final magnification 32 000).
