Fig. 225.^—Section of the anterior part of an eye which had a perforating ulcer of the cornea and incarceration of the iris. Glaucoma ensued, and the cornea in the region of the cicatrised ulcer stretched and became staphylomatous. A, substantia propria of the cornea; B, staphyloma; C, iris, which is adherent to the base of the old ulcer; D, anterior polar opacity in lens. if the perforation be large, the vitreous and even the retina may prolapse. The lens may come in contact with the back of the cornea and the exudate adhere to the anterior capsule. The contact of the lens with the base of the ulcer causes proliferation of the cells lining the anterior capsule and a subcapsular opacity of the lens is the result (acquired ante- rior polar cataract) (see page 596). When the ulcer heals the anterior chamber is re-formed, and a band of fibrous.
