Argon laser photocoagulation performed to destroy retinal neovascularization in two patients with proliferative sickle retinopathy and one patient with sarcoidosis was complicated by the development of choroidal neovascular tissue that extended through the photocoagulated retina into the vitreous. Attempts to obliterate the neovascular growth were successful in two cases. In the case that did not respond to repeated therapeutic procedures, the possibility of a direct communication with the long posterior ciliary artery was suggested by the presence of a chorioretinal defect in the vicinity of the photocoagulated area.
