Red-free Photograph l Digital red-free photograph shows: – Lipid, blood and fluid in exudative AMD

Early-phase Fluorescein Angiogram Image courtesy of J Slakter

Early-phase Fluorescein Angiogram l Early phase: – Well-defined classic CNV centrally – Stippled mild hyperfluorescence from occult CNV surrounding classic CNV – Blockage from blood

Late-phase Fluorescein Angiogram Image courtesy of J Slakter

Late-phase Fluorescein Angiogram l Late phase: – Leakage from the central classic CNV – Surrounding area of stippled fluorescence from occult CNV

Identification of lesion components l Digital tracing of the classic component of the CNV – Classic CNV is traced in the early phase when it is best delineated

Identification of lesion components l Digital tracing of the occult component – Occult component is measured in the late phase where the entire extent of involvement can be seen

Minimally Classic CNV Because the lesion consists of less than 50% classic CNV, it is considered “minimally classic CNV” Classic Occult Images courtesy of J Slakter
