外伤性脉络膜破裂的吲哚青绿血管造影

目的探讨脉络膜破裂(choroidal rupture,CR)的吲哚青绿血管造影(indocyanine green angiography,ICGA)和荧光素眼底血管造影(fundus fluore scein angiography,FFA)的影像学表现及其同步检查的意义。方法对17例眼挫伤致CR患者的17只患眼进行FFA和ICGA同步检查，并对FFA和ICGA结果进行对比分析。结果CR部位FFA显示为强荧光，ICGA显示为弱荧光；5只眼(29.4%)ICGA显示CR 长度较FFA所显示的长；有6只眼(35.3%)在出血灶内，ICGA显示出FFA不能显示的隐匿CR带。结论ICGA较FFA能更好地确定脉络膜裂伤的范围和程度 ，FFA和ICGA同步检查能全面地了解CR的程度和眼底各组织的病理变化。(中华眼底病杂志,2001,17:30-32)

Indocyanine green angiography in traumatic choroidal rupture

Purpose To define the morphometric characteristics and the implication of simultaneous fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) in traumatic choroidal rupture. Methods Simultaneous FFA and ICGA were carried out in 17 patients (17 eyes) with traumatic choroidal rupture. Results Choroidal ruptures were shown as hyperfluorescence region in the early phase of FFA,and as hyperfluorescence in the late phase of FFA but in ICGA were shown as hypofluorescence region in both early and late phases.The rupture regions in ICGA were longer than that in FFA in 5 patients (5 eyes).The rupture regions in 6 patients (6 eyes) with hemorrhage could be shown in ICGA,but couldn't be shown in FFA. Conclusion ICGA is helpful in diagnosing minor choroidal ruptures,in defining the extent of traumatic choroidal ruptures,and in further understanding the pathological changes of choroidal ruptures.
