[Manifestations of fluorescein angiography in choroidal melanoma].

This paper reported on the manifestations of fundus fluorescein angiography in 21 patients with choroidal melanoma. According to the findings of fluorescein angiography, we suggest that this disease can be classified into 3 types: type I shows hyperfluorescent mottles (12 cases); type II shows hyperfluorescent spots and patches, (4 cases); type III shows a dark area in the tumor body, (5 cases). The angiographic characteristics of the three types of melanoma and their histopathologic changes are discussed. The differential diagnosis of the three types of melanoma from metastatic choroidal carcinoma, senile macular degeneration with subretinal hemorrhage and choroidal hemangiomas is discussed. For the first time choroid melanoma has been classified into 3 types according to fluorescein angiography. It may contribute to the early diagnosis of this disease.
