Objective Observation on the characteristics of choroidal melanomas with indocyanine green angiography (ICGA) and fundus fluorescsin angiography(FFA). Methods Both ICGA and FFA were used in 16 cases of choroidal melanoma for comparison and analysis. Results 81.2% of tumors showed hypofluorescence all the way or faint fluorescence in later stage．62.6% of tumors had characteristic intrinsic tumor vassels with ICGA,while 12.5% of tumors had intrinsic vessels with FFA．Those tumors that can't be diagnosed owing to whole hyperfluorescence in later stage with FFA may be diagnosed by visibility of intrinsic tumor vessels with ICGA. Conclusion ICGA is helpful in the diagnosis of choroidal melanoma. (Chin J Ocul Fundus Dis, 2000，16：3-5)
