Cyst; m, inflammatory membrane in pupil; /, lens; r, detached retina. Cysts due to congenital defect in the involution of the secondary optic vesicle are described under congenital aberrations (see page 18). In inflammation of the iris, adhesion of the posterior layer of pigment epithelium to the lens capsule and the collection of serous fluid between it and the anterior layer, over a portion of its extent, is of common occurrence. Clinically the appearance produced is that of a localised condition of iris bombe (Fig. 128). If an iridectomy be performed in such a case, the stroma and anterior layer of pigment epithelium will be removed, but the posterior layer will be left adherent to the lens capsule, filling up the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Collins, E.
