Introduction. Although fluorescein angiographic characteristics of choroidal tumors are well defined, there are only few studies which have documented the indocyanine green angiographic features.

Methods. Fluorescein (FA) and Indocyanine Green Angiographies (ICGA) were performed on 70 patients. There were 58 patients (61 eyes) with choroidal nevi, 6 patients (6 eyes) with choroidal melanoma, 4 patients (6 eyes) with choroidal metastasis, 1 with osteoma and 1 with hemangioma.

Results. Only 8 out of 63 nevi were well marked on FA. They were all well defined on ICGA, showing hypofluorescence. Choroidal melanomas showed irregular hyperfluorescence in 4, double circulation in 1, and hypofluorescence in the central with hyperfluorescent border in 1 patient on early phase FA. Late phase FA showed hyperfluorescence in all cases. Early phase ICGA demonstrated hypofluorescence in all cases. Late phase ICGA showed hyperfluorescence in 4, hypofluorescence in 1, and three-ring pattern in 1 eye. In metastatic tumors, early phase FA showed hypo and hyperfluorescence in 3 patients, and hypofluorescence in 1. Late phase FA showed hyperfluorescence in all cases. ICGA findings of metastatic lesions were variable. Choroidal hemangioma had an early hyperfluorescence on FA and ICGA. In choroidal osteoma, FA showed a patchy hyperfluorescence and ICGA showed hypofluorescence in the early phase.

Conclusion. ICGA is not a first hand diagnostic tool but is definitely helpful in improving visualization, documenting the properties and beneficial in the follow up of choroidal mass lesions.
