This serous detachment occurs not infrequently in the days immediatelysucceeding an extraction of cataract or an iridectomy for glaucoma [also quite fre-quently after Elliots trephine operation and still more frequently after Lagrangessclerectomy (Barkan).—D.] It gives a good prognosis, since usually the chorioid becomesreattached to the Fig. 206.—Rupture of the Chorioid. Right Eye. (After De Wecker.) There are one large and four small ruptures in the lower part of the chorioid. The large ruptureappears under the guise of a slightly curved white band with jagged, somewhat pigmented small ruptures lie concentric with the large one and between it and the papilla. Over all of themthe retinal vessels run unaltered. 428. Rupture of the Chorioid.—This is produced through the action of some bluntbody upon the eyeball (contusion). Immediately after the injury the blood extrav-asated into the vitreous usually prevents a clear view of the interior of the eye. Afterthe absorption of the blood the rupture of the chorioid, which ordinarily lies in theneighborhood of the papilla, and most frequently to the outer side of it, is there is only one, sometimes there are several lacerations. They form long,yellowish-white streaks, as the edges of the laceration in the chor
