Since this case was seen and operated upon in a comparatively early stage of its development, the final changes as described by the writers who have recorded similar cases have not had a chance to appear. The relationship to injury seems to have been particularly noted by all those with whose names the implantation theory is especially associated. Rothmund, in 1871, collected 36 cases, in which 28 had a perforating wound; in 3 there were eyelashes in the anterior chamber, in 2 cysts followed cataract operations. The cases of the pearl tumor type of new growth are composed, histologically, of solid concentric lamellae of epithelium arranged like the layers of an onion. Becker reported a cyst with compact walls, many elastic fibers, and lined with flattened epithelium. Stolting described two epithelial cysts, and pointed out the possibility of continuity of the epithelium with that of the surface by downward growth along the lips of the wound into the anterior chamber. Parsons states that the contents of these cysts are generally a serous or slightly turbid fluid, and in these cases the iris is often split into two layers; the anterior is often adherent to the back of the cornea, and is usually thin and atrophic. The posterior layer constitutes the greater part of the iris and forms the posterior wall of the cyst, which is, as usual, lined with irregular and often ill-developed stratified epithelium.
