Ocular findings in the intravenous drug abuser.

Two patients with talc emboli of the retinal vasculature, both of them intravenous drug abusers, are described. One underwent a pars plana vitrectomy for removal of the vascularized vitreous mass that obscured the retina. The vitreous mass was presumably a result of retinal neovascularization secondary to the talc embolic. Other ocular findings that may be observed in the intravenous drug abuser are described.
