CHORIO-RETINITIS

(Lat.), n. f. Kor(ch2o2r)"i"-o(o)-re2t- (rat)-i2n-i(e)'ti2s. Gen., chorio-retinit'idis. See CHORIOIDO-RETINITis. C.-r. central is. Fr., chorio- (ou choro'ido-) retinite centrale. Ger., centrale C.-R. It., corio-retinite centrale. Sp., corio-retinitis central. A plastic c.-r. similar to c.-r. cir cum script a, but characterized by the appearance of the spots and patches of exudation and proliferation in and around the macula lutea and the optic disc. [F.] C.-r. cir cum script a. Fr., chorio-retinite cir A proce similar to that which appears in c.-r. dis semi nat a, but conscrite. Qer.,umschriebene C.-R. It., corio-retinite circoscritta. characterized by the appearance of a single large deposit of infiltration or of a single group of small exudations of a brilliant yellow color, which subsequently coalesce and become one. [F.] C.-r. dis semi nat a. Fr., chorio-retinite di eminee. Ger., di eminirte C.-R. A c.-r., usually of syphilitic origin, characterized by circumscribed exudation ma es between the chorioid and retina, followed by atrophy of the hexagonal epithelium and firm adhesion of the retina to the chorioid at the spots of exudation. As the disease progre es, these spots coalesce, until the entire fundus is involved. There is sometimes marked proliferation of the connective ti ue and epithelium. It ends in atrophy of the optic nerve. [F.] C.-r. pigmentosa. The condition existing in the later stages of c.-r. dis semi nat a, when the spots of exudation in the chorioid have been absorbed and the choripidal stroma has become thinned, allowing the white sclerotic to shine through in patches. Around these patches the epithelial cells proliferate and increase in size, forming a more or le marked black girdle. [F.] Equatorial c.-r. Fr., chorio-retinite equator i ale. A c.-r. seated in the periphery of the retina. [L, 88.] CHORIPETAI^E (Lat.), n. f. pi. Kor(ch2or)-i2-pe2t'a2l(a3l)-e- (as-e2). From x^P4*. separately, and irera^ov, a leaf. See POLYPETALjE. [s. 261]
