A 47-year-old man presented with blurred vision in the right eye and was diagnosed as having idiopathic subfoveal choroidal neovascularization, which progressed to choriovitreal neovascularization in 2 weeks. Optical coherence tomography imaging revealed a subfoveal choroidal neovascularization breaking through the surface of an intact retina and growing as an epiretinal fibrovascular membrane accompanied by vitreomacular traction. Pars plana vitrectomy and removal of the choriovitreal neovascular membrane were performed.
