Photodynamic therapy for iatrogenic CNV due to laser photocoagulation in central serous chorioretinopathy.

The authors report the result of photodynamic therapy for iatrogenic choroidal neovascularization from focal argon laser photocoagulation in a case with central serous chorioretinopathy. A 45-year-old woman who developed choroidal neovascularization after focal argon laser photocoagulation for chronic central serous chorioretinopathy was treated with ocular photodynamic therapy with verteporfin. Choroidal neovascularization became inactive clinically a month after photodynamic therapy. Fluorescein angiography and optical coherence tomography demonstrated the resolved choroidal neovascularization. Baseline visual acuity improved from 20/40 to 20/20 after photodynamic therapy. The patient's condition remained stable 2 years postoperatively. Photodynamic therapy was beneficial for the outcome of iatrogenic choroidal neovascularization that developed after laser treatment for longstanding central serous chorioretinopathy.
