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.

Objective
To observe the findings of indocyanine green angiography(ICGA) and fundus fluorescein angiography (FFA) of the patients with multifocal posterior pigment epitheliopathy(MPPE).
Methods
ICGA and FFA were performed in 6 cases(7 eyes)of MPPE and the findings were analysed and compared between these examinations.
Results
Five cases(5 eyes)were found to be in the active stage of the disease under FFA,and among them 4 eyes(80%)showed delayed choroidal perfusion at the early stage of ICGA.During the active stage of the disease,ICGA showed leakage relative to FFA leakage,and there were diffuse hyperfluorescence around the points of leakages as well as in the posterior pole of ocular fundus.In convulescence,although FFA revealed no obvious leakage,ICGA still denoted the presence of leakages.
Conclusions
MPPE was considered to be the more serious type of central serous chorioretinopathy showing the same but more extensive ICGA abnormality.
