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.

持续性扁平状黄斑病变(PPM)是一种罕见的临床病症,此前文献中有报道,其在多模态成像上具有特征性表现,包括在荧光素血管造影(FA)和吲哚菁绿血管造影(ICGA)上观察到的低荧光。针对这种低荧光提出的主要机制包括脉络膜血管受损,脉络膜毛细血管无灌注和/或炎性沉积物阻断脉络膜荧光。本报告展示了一名58岁急性起病的PPM女性患者脉络膜视网膜灌注的先前未报道的特征。光学相干断层扫描血管造影证实脉络膜毛细血管灌注不足,与FA和ICGA上所见的灌注不足相对应。[《眼科手术、激光与视网膜成像》。2017年;48:1026 - 1031。]
