The aim of the study was to report the clinical utility of optical coherence tomography angiography (OCT-A) in characterizing and differentiating inflammatory lesions and choroidal neovascularization (CNV) in multifocal choroiditis (MFC). A patient affected by MFC complaining central visual loss and scotoma in his left eye was fully investigated with dye-based angiographies, structural OCT and OCT-A. A reactivation of macular CNV was initially suspected, while OCT-A revealed the absence of any decorrelation signal both over the retinal pigment epithelium (RPE) and between RPE and Bruchs' membrane. OCT-A is a promising tool in detecting inflammatory CNV and in differentiating CNV from primitive inflammatory damage. Finely characterizing the aspect of a lesion allows us to choose the best therapeutic strategy for managing these potentially blinding diseases.
