Summary Sectors of anterior segments of vervet eyes were exposed to solutions of different osmolarities (Cercopithecus aethiops). After hypertonic incubation followed by isotonic fixation, as well as after fixation directly in hypertonic fixative, the ciliary epithelium showed constant changes. These changes consisted of a shrinkage pattern with dilations of intercellular clefts in the superficial region of the epithelium, whereas no dilations occurred in the basal layer. The basal junctional complex of the superficial cell layer was always intact. The detailed structure of this complex is described. The conclusion is drawn that it functions as a barrier to the molecules of the solutes in question, and that it may also have this function in vivo with regard to molecules of similar size.
