Abstract： 目的比较荧光素眼底血管造影(fundus fluorescein angiography,FFA)和吲哚青绿血管造影(indocyanine green angiography,ICGA)对老年性黄斑变性(age-related macular degeneration, AMD)视网膜下出血中脉络膜新生血管膜(choroidal neovascularization, CNV)的定位、分型,以及对出血面积测量的效果. 方法选取经眼底彩色照相、FFA和ICGA检查确诊为AMD视网膜下出血的177例患者(177只眼)的相关资料,分别在其FFA和ICGA图像上进行CNV的定位和分型,并从中随机抽取30例AMD视网膜下出血患者的FFA和ICGA图像进行出血面积测量. 结果 FFA图像显示,177例患者中,160例患者(90.4%)的CNV能够较明确定位和分型,24例患者(13.6%)的CNV符合激光光凝条件; ICGA图像显示,175例患者(98.9%)的CNV能够较明确定位和分型,51例患者(28.8%)的CNV符合激光光凝条件.2种造影检查对CNV定位和分型的差异均无显著性的意义(Z=-0.383,P=0.701;χ2=2.993,P=0.810).视网膜下出血的面积测量中,由FFA测得的数值(=26.610 mm2,M=13.548 mm2)较ICGA(=24.714 mm2,M=12.875 mm2)大,差异有显著性的意义(Z=-3.000,P=0.003). 结论 ICGA检查不但能提高AMD视网膜下出血中CNV显影的可能性,还能提高AMD患者激光光凝治疗的可行性;而FFA对评估AMD视网膜下出血的面积效果较好.
