A representative example of image correlation obtained by different imaging modalities from the same patient by aligning retinal blood vessels to display the CCI location in relation to the leaking point(s)on fluorescein angiography (FA) and corresponding structural changes on optical coherence tomography angiography (OCT). a Superimposition of the 3 × 3 OCTA density map and the scanning laser ophthalmoscopy (SLO) OCT on FA images. b FA shows superonasal parafoveal leaking points, the area scanned by OCT (white rectangle) and the area scanned with OCTA (yellow rectangle). c Superimposition of the (SLO-OCT)image on FA image and orientation of the OCT line scan passing through leaking points (green arrow). d Superimposition of 3 × 3 OCTA density map image on FA image to display CCI location in relation to the leaking points. e Enhanced depth imaging (EDI) OCT line scan showing focal RPE alterations with underlying pachy choroidcoinciding with CCI location on density map and leaking points on FA (yellow oval)
