    anterior chamljer; the pupillary margin at this point is straight instead of circular and does not react. The iris may be completely or partially detached in ruptures of the sclerotic (!oat, a condition termed traumatic irkleremia or aniridia; or the iris may be folded back on itself (Plate 34, b). All these injuries of the iris may be attended 'with hemorrhage into the anterior chamber and disloca- tion of the lens. 3. Tumors of the Iris and Ciliary Body. Cysts usually develop after perforating -wounds of the anterior chamber. They are generally benign, though somewhat difficult to remove. Operation should not be delayed, because there is danger of glaucoma and conse- quent loss of vision. Sarcoma occasionally occurs in the iris and ciliary body. It is usually pigmented, the color ranging from gray to dark-brown or black, and very malignant. A sarcoma sometimes develo])S from small pigment-spots in the iris which have been j)resent a long time ; the growth is at first very slow, but gradually a large mass is formed (Plate 30, o), which, if left to itself, breaks through the outer coat. Sarcoma of the ciliary body may escape de- tection a long time, tintil finally it emerges on the perijdi- ery of the anterior chamber. If the sarcoma is limited to the iris and is very small, it may be excised ; but if the sar- coma is large, or situated in tlie ciliary body, enucleation is necessary to save the ])atieni’s life. Tubercular tumors have been referred to under Iritis. DISEASES OF THE LENS. The crystalline lens, being a non-vascnlar structure, is not subject to inflammation ; at the most it may be in- vaded secondarily by pus-corpuscles after rupture of the capsule by traumatism or stippuration.
