Posterior Pigment Epithelium
Most of the intercellular junctions present here are maculae occludentes and only a few desmosomes are present; desmosomes are not found in the muscular portion. The apical surface of the anterior epithelium is contiguous with that of the posterior epithelium. Desmosomes and tight junctions join the two layers, but there are some areas of separation (f) between the cells. The spaces so formed are filled with microvilli and an occasional cilium is also found here (double arrows).
