Figure 1: Quantitative analysis of fluorescein angiography images using the reading center GRADOR developed by Doheny Image Reading Center (DIRC, Doheny Eye Institute, Los Angeles) software engineers. CNV lesion components are manually delineated and the area of various CNV lesion components is calculated by the software. A: Early phase, B: Late phase, C: Graded image (blue: classic CNV lesion component, green: blocked fluorescence).
