This report demonstrates simultaneous choroidal neovascular membrane occurrences in idiopathic polypoidal choroidal vasculopathy, indicating crucial diagnostic considerations.
Idiopathic polypoidal choroidal vasculopathy (IPCV), a rare retinal condition initially described in 1982, is characterized by retinal pigment epithelial (RPE) detachments associated with choroidal polypoidals. Although it is recognized as a unique entity, many consider it a peculiar representation of choroidal neovascular membrane (CNM), commonly associated with age‐related macular degeneration (ARMD). We report a case of IPCV with simultaneous presentation of CNM. Dilated examination and fluorescein angiography (FA) revealed RPE detachments associated with choroidal polypoidals. FA also revealed a lacy hyperfluorescent vascular lesion. Ocular manifestations, differential diagnoses, and treatment options are discussed, with emphasis on similarities and differences between IPCV and CNM. It is imperative to consider IPCV in the differential diagnosis of RPE detachments, including those associated with CNM. Careful funduscopic evaluation, FA, and/or indocyanine green videoangiography analysis helps confirm the diagnosis.
