Multimodal imaging of choroidal melanomas. A, B, Wide-angle color fundus photographs document the tumor borders and surface appearance of 2 choroidal melanomas. C, FAF image of the lesion shown in part A reveals increased diffuse autofluorescence associated with subretinal fluid adjacent to the variably autofluorescent tumor (asterisk). Increased autofluorescence is associated with the lipofuscin (arrow). D, FAF image of the lesion shown in part B. The highly elevated tumor blocks under lying FAF. Diffusely increased autofluorescence is associated with subretinal fluid adjacent to the tumor (arrow). E, B-scan ultrasonography reveals the dome shape of the tumor shown in parts A and C. F, B-scan ultrasonography reveals the collar-button shape of the tumor shown in partsB and D. Images obtained from B-scan ultrasonography are helpful in measuring tumor size. G, H, Corresponding A-scan ultrasonographic image reveals a low, regular internal reflectivity associated with each melanoma.
