Answer

Answer

Fluorescein angiography and indocyanine green angiography do not show pathognomonic signs of choroidal melanoma but can help point to its diagnosis

Small choroidal melanomas may show fluorescein angiographic changes similar to some choroidal nevi, with such changes ranging from normal angiography to hypofluorescence secondary to blockage of background fluorescence

Larger melanomas may show a patchy pattern of early hypofluorescence and hyperfluorescence followed by late intense staining

Simultaneous fluorescence of retinal and choroidal circulation within the tumor is fairly distinctive of choroidal melanomas
