Persistent placoid maculopathy (PPM) is a rare clinical entity that has previously been reported in the literature with a characteristic appearance on multimodal imaging, including hypofluorescence observed on fluorescein angiogram (FA) and indocyanine green angiography (ICGA). The leading mechanisms proposed for this hypofluorescence include impaired choroidal vasculature with nonperfusion of the choriocapillaris and/or blockage of choroidal fluorescence by inflammatory deposits. This report demonstrates previously unreported characteristics of chorioretinal perfusion in a case of acute onset PPM in a 58-year-old woman. Optical coherence tomography angiography confirmed hypoperfusion of the choriocapillaris corresponding to the hypoperfusion seen on FA and ICGA.
