A. Introduction  Since the publication of the analysis of the ultrastructure of normal and acetazolamide (Diamox)-treated nonpigmented ciliary epithelium in the rabbit eye (Holmberg, 1957), the investigation has been extended to include the pigment epithelium in adult rabbit and both epithelial layers in monkey, human, and young rabbit eyes. The ultrastructure of the ciliary body capillaries and of
