Laser photocoagulation–induced choroidal neovascularization (CNV) is an uncommon iatrogenic complication following thermal laser treatment for diabetic macular edema and proliferative diabetic retinopathy.1 Disruption of the retinal pigment epithelium–Bruch membrane complex due to intense laser energy presumably leads to the development of CNV.1,2 We report a dramatic case of laser-induced CNV initially associated with a chorioretinal mass lesion that displayed characteristics of an atypical secondary vasoproliferative tumor. The chorioretinal lesion evolved to anastomose extensively with the retinal vasculature.
