Chorioretinal vascular anastomoses after perforating trauma to the eye.

A 32-year-old white man sustained an ocular injury with a small piece of metal. He had perforation of the retina and choroid, and later developed chorioretinal vascular anastomosis. Disabling complications, such as neovascular growth, serous transudation, or hemorrhages, did not occur within a ten-month follow-up period. Interruption of Bruch's membrane and the retinal pigment epithelium, with approximation of the normally separated vasculatures of the choroid and retina, appears necessary for such anastomoses to occur.
