Intravitreal polypoidal choroidal vasculopathy in radiation retinopathy.

A 30-year-old woman diagnosed with choroidal melanoma and treated with plaque radiation and transpupillary thermotherapy 5 years earlier presented with recalcitrant proliferative radiation retinopathy despite multiple intravitreal anti-vascular endothelial growth factor injections. Swept-source and spectral-domain optical coherence tomography (OCT) demonstrated intravitreal polyps lying on the surface of atrophied chorioretinal tissue. Fluorescein angiography (FA) revealed leakage from these saccular choroidal neovasculopathic vessels adjacent to a large zone of poor choroidal perfusion. Intravitreal polypoidal choroidal vasculopathy may be associated with radiation retinopathy and is well-demonstrated with swept-source and spectral-domain OCT and FA.
