Some of the connective tissue and hemorrhage found in Kuhnt-Junius disciform degeneration of the macula has recently been shown to come from the choroid through breaks in Bruch's membrane.1 Furthermore, long stretches of vascularized tissue between the choroid and the retina have been reported anterior to the equator in otherwise normal eyes.2 Indeed, Wolfrum3 found tissue between the lamina elastica and the basal membrane in older persons thirty years ago, but his observation has been given scant attention. Further data concerning such tissue would therefore seem highly desirable.
In the case reported here long stretches of vascularized preequatorial tissue were found between Bruch's membrane and the pigment epithelium without demonstrable breaks in the membrane.4 In addition, there was a large mass of retroretinal tissue and blood in the macular region. Capillaries, connective tissue and blood entered this tissue from the choroid through breaks in Bruch's membrane.
