高度近视眼荧光素眼底血管造影与吲哚青绿血管造影分析

目的 探讨高度近视眼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）同步检查的影像学特征及其临床意义。 方法 随机选择屈光状态-6 D以上的高度近视患 者30例57只眼，进行FFA和ICGA同步检查，对比分析其FFA和ICGA检查图像。 结果 57只眼中FFA显示早期背景 荧光减弱25只眼，晚期显示新生血管形成10只眼，漆纹样裂纹形成40只眼；ICGA显示睫状后短动脉8只眼，背景荧光减弱35 只眼，脉络膜新生血管形成8只眼，漆纹样裂纹形成52只眼。 结论 高度近视眼的FFA和ICGA 检查的影像学特征主要表现为背景荧光减弱，漆纹样裂纹及脉络膜新生血管形成。FFA 和ICGA 同步检查能更全面地了解高度近视患者眼底视网膜与脉络膜的病理变化，有助于全面地了解病情和指导进一步治疗。 （中华眼底病杂志，2003，19：87-89）

Analysis of indocyanine green angiography and fundus fluorescein angiography for high myopia

ObjectiveTo investigate the iconographic characteristics and clinical significances of synchronic examination of indocyanine green angiography (ICGA) and fundus fluorescein angiography (FFA) for high myopia.MethodsThirty patients (57 eyes) with high myopia(>-6.00D), selected randomly and consecutively, were examined by ICGA and FFA synchronically.ResultsThe result of early phase of FFA showed hypofluorescence of the background in 25 eyes,while of late phase showed subretinal neovascularization (SRNV) in 10 eyes and streak formation in 40 eyes. The result of ICGA showed choroidal retrobulbar arteries in 8 eyes, hypofluorescence of the background in 35 eyes, SRNV in 8 eyes, and streak formation in 52 eyes.ConclusionThe iconographic characteristics of ICGA and FFA of high myopia include hypofluorescence of the background, SRNV and streak formation. ICGA can give more exact information on the lesions of choroid in high myopia. The synchronic examination of ICGA and FFA may act as a guide to the therapy for high myopia.
