渗出型老年黄斑变性的吲哚菁绿血管造影图像特征

目的 探讨渗出型老年黄斑变性(AMD)吲哚菁绿血管造影(ICGA)与荧光素眼底血管造影(FFA)比较的图像特征。方法 对52例65眼渗出型AMD患者进行了眼底彩色照相、FFA和ICGA检查。结果 渗出型AMD的65眼中，ICGA诊断为典型性脉络膜新生血管(CNV)有33跟．占50．8％，FFA诊惭为典型性CNV有8眼，占11．6％；FFA诊断为隐匿性CNV的35眼中，ICGA诊断为边界清楚或久清楚的斑状CNV有22眼；合并黄斑出血39眼中，FFA不能发现的CNV而ICGA能发现共5眼；FFA诊断为痕痕染色的7眼中，有2眼有ICGA中发现CNV；ICGA发现CNV的供养血管(feeding vessel)有3眼。结论 ICGA比FFA发现CNV诊断率高，准确地显示黄斑出血所掩盖的CNV，ICCA有助丁发现CNV的供养血管。

Indocyanine green angiography of exudative age-related macular degeneration

Objective To discuss image characteristics of Indocyanine green angiography( ICGA ) for exudative age-related macular degeneration( AMD) and compare with that of fundus fluorescein angiography( FFA ). Methods Sixty-five eyes of 52 patients with exudative AMD underwent FFA,ICGA and fundus photography. Results ICGA showed 33 eyes(50. 8% ) to be choroidal neovascularization (CNV) but FFA showed 8 eyes( 11.6% ) classic CNV. ICGA revealed 22 eyes CNV from 35 occult CNV eyes in FFA ; 5 eyes displayed CNV in ICGA, but they could not be found in FFA in 39 eyes with macular hemorrhage. ICGA showed 2 eyes CNV in 7 eyes with dyeing scar in FFA. 3 eyes were seen to have feeding vessel in ICGA and 6 eyes appeared hyperfluorescence in late FFA. Conclusions ICGA can improve the diagnostic ratio ol CNV with macular hemorrhage, and helps to find feeder vessel and hot sport of CNV.
