Punctate inner choroidopathy (PIC) is a relatively uncommon inflammatory multifocal chorioretinopathy that predominantly affects young, myopic women. Subfoveal choroidal neovascularization (CNV) often leads to rapid loss of sight. Fluorescein angiography (FA) and indocyanine green angiography (ICGA) remain the existing gold standards for CNV diagnosis. However, these methods are invasive and time-consuming. Recently, optical coherence tomography angiography (OCTA) has been used more frequently as an adjunct to FA/ICGA...
