CYST OF THE IRIS is apt to follow a penetrating wound in which a bit of epi thelium or eyelash has been implanted on the iris. It may have the form of a serous cyst occupying a large- part of the an terior chamber, or an epithelial pearl on the surface of the iris. Either form may cause secondary glaucoma. It should be excised.
Case of idiopathic cyst of the iris, which throws more light upon personal belief that they are the result of incapsu lation of an iris-crypt by bands which have become thickened and enlarged by some pathological process. Schmidt Rilnpler (Archiv f. Ophthal. (Grilfe), Apr., '89).
Cyst of the iris observed to develop after the performance of an iridectomy, with removal of a cilium from the an terior chamber and the discission of a secondary cataract, in an eye which had been injured eleven years previously. Burnett (Archives of Ophthal., Apr., '92).
Case of epithelial pearl-tumor in the iris following the implantation of an eye lash into the anterior chamber. When first seen, seven months after the injury, the cilium was extracted and an un successful attempt was made to remove the tumor. One year later the growth had increased in size, and the eye WaS enueleated on account of sympathetic irritation. The tumor, which was sur rounded by pigmented iris-tissue, was found to be free from the cornea, ciliary body, and vitreous, and proved to be cyst lined by laminated epithelium and containing an opaque NI hitc substance, composed of fat-globules and polyhedral cells. Cross and Collins (Lancet, July l5, '93).

The inion given that these are uveal cysts, nat secondary to malignant neoplasms, and p(rhaps arising from the anterior border of the ciliary body. M. W. Zim mermann (Ann. of Ophtli., July, '97).
Gr)t)l.t may develop in the iris, caus ing one or more rounded swellings, at tended with iritis; or in the ciliary body, where it is also attended with inflam mation, and may cause ciliary Ionia either from its primary swelling or by thinning of the overlying sclera by absorption so that it cannot resist ocular pressure. In the iris it usually leaves a thinned and atrophied spot through which may in some cases be seen the fundus-reflex. Active antisyphilitic
treatment is indicated.
Rare case observed of gummatous iritis the result of hereditary ryphilis, in a female child 7 months old. The anterior chamber was filled by an hoemorrhagic exudate, the iris being almost unrecog nizable. Liebrecht fahender's Monats. f. Augenh., -May, '91).
Two cases of syphilitic g,urnma of the ciliary body. The tumor passed through the iris angle into the anterior chamber and invaded the iris, hich was also the seat of the usual condylomata. In one case there was a perforation of the sclera and conjunctiva through which the most of the broken down tumor-mass was evacuated. Under treatment the results in both cases were good. Callenga (Anna]. di Ottal., xxv, 2, 3, p. 210).
Differential diagnosis of gumma and sarcoma of ciliary region: first, early iritis, vitreous opacities, perhaps dimin ished tension, rapid evolution, and bulg ing of sclera; second, slow non-Milani 11111tory onset with glaucoma later; thorough therapeutic test to be made before enueleation. Roclion-Duvigneaud (Ileum COI. de Clin. et de Th6r. Jour. des Prat.. Apr. 13, '95).
Case of unilateral syphilitic iritis, with typical guninia, occurring in a man 25 years old, three months after chancre of the lip, and preceded by roseola, mucous patches, etc. Cure was ap parently obtained after a month's treat ment, but a second attack was precipi tated by instillation of pilocarpine. The inflammation was ultimately cured with out any trace of the affection, vision being absolutely perfect six months after. Armaignac (Recueil d'Ophtal., Mar., '96).
Three cases of gumma of the ciliary body observed in patients 21, 27, and 26 years old. They appeared 2 years, 6 months, and 2 years after the initial lesion. One preserved a certain degree of sight in spite of scleral perforation. In the other two the globe atrophied. Injections of calomel once a week gives the best results, but they should be com bined with inunctions and with injections of the soluble salts of mercury- daily. Terson (Archives d'Ophtal., July, '06).
True gumma of the ciliary body that filially- yielded to specific treatment wit nessed two and a half years after the primary infection. In addition to the signs of syphilitic iritis, there was bulg ing forward of the iris adjacent to flie tumor, producing different depths in the anterior chamber. gurnmatous growths in the iris, circumscribed discoloration and distinction of the sclera (ciliary staphyloma), and almost total loss of vision from exudation into the vitreous and the pupillary area.
