Abstract

The two layers of cells forming the epithelium of the processes of the ciliary body are characterized by extensive elaborations of their membranes. The elaboration of the membranes of the cell layer facing the posterior chamber is of two types: (a) infoldings of the free surface facing the Posterior chamber and (b) interdigitations of the margins between adjacent cells (Pappas and Smelser1 and Holmberg2). Similar elaborations of cell membranes have been found in cells of other tissues engaged in secretion (Pease3).

It was reported previously that the experimental alteration of normal aqueous humor secretion by various agents produces changes in the fine structure of the cells. The most obvious changes noted were an increase in the number of vesicles in the cytoplasm and the concomitant disappearance of the infoldings and interdigitations.1 Thus the loss of the infoldings and interdigitations of the ciliary epithelial cells is a
