Optical coherence tomography angiography (OCTA) for differentiating acute inflammatory lesions from choroidal neovascularization in a myopic eye with idiopathic multifocal choroiditis. a Color photograph shows multiple yellowish-gray lesions perifoveolar and nasal the optic nerve head. b Fundus autofluorescence in this case shows unspecific mottled hypoautofluorescence of the lesions. c Structural OCT scan over the lesion within the green box in panel B shows hyperreflective material below and minimal above the retinal pigment epithelium (RPE). d Cross-sectional OCTA of the same lesion demonstrates slightly abnormal flow above the RPE, representing type 2 neovascularization. e En face OCTA reconstruction, which shows a small choroidal neovascularization. f Structural OCT scan over the lesion within the yellow box in panel b shows hyperreflective material below the RPE and a well-defined Bruch’s membrane. g Cross-sectional OCTA shows the absence of abnormal flow beneath the RPE. The flow overlying the RPE layer represents the projection of the flow signal from the more superficial retinal circulation (projection artifact). h En face OCTA reconstruction. It looks like vascular branches of a choroidal neovascularization, but scrolling the slap through the retina represents a projection artifact
