Detection of the posterior border. The upper grouped images (A) show a color fundus image, an infrared image and a corresponding high-resolution OCT B-scan, with depicted lesion boarders (black arrowheads). Detection of the posterior border was possible where reflectivity changed from hypo- to hyperrflectivity (white arrowheads). The middle grouped images (B) show the corresponding modalities of a lesion, where the choroids posterior border could only be captured in the normal tissue adjacent to the lesion (white arrowheads). The lower grouped images (C), show the corresponding imaging modalities of a larger lesion, where the posterior choroidal border was only detectable in adjacent normal tissue (white arrowheads), but not in the lesion
