脉络膜黑色素瘤的吲哚青绿和荧光素眼底血管造影

Indocyanine green angiography and fundus fluorescein angiography in choroidal melanoma.

目的 观察脉络膜黑色素瘤的吲哚青绿血管造影 (indocyanine green angiography,ICCA)和荧光素眼底血管造影 (fundus fluorescein angiography,FFA)的特征 方法 16例病人采用 ICGA和 FFA检查 ,对两种造影图像进行对比分析 结果 ICGA检查 81.2 %的肿物不显荧光或晚期呈弱荧光 ,6 2 .5 %肿物可见有诊断特征的瘤体血管 ,FFA检查仅 12 .5 %肿物可见瘤体血管 ,肿物在 FFA晚期呈强荧光不能确诊时 ,ICGA可见瘤体血管以助诊断。 结论 脉络膜黑色素瘤

Objective [WT5”BZ]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 .
