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 5 7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 5 7只眼中 FFA显示早期背景荧光减弱 2 5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 5 2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。
Objective To investigate the imaging features and their clinical significance of synchronous high-myopia fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA). Methods A total of 57 eyes of 30 high myopia patients with refractive status more than 6 D were enrolled in this study. FFA and ICGA were examined synchronously, and their FFA and ICGA images were compared. Results FFA in 57 eyes showed 25 eyes with early background fluorescence loss, 10 eyes with neovascularization in late stage and 40 eyes with lacquer pattern cracks. ICGA showed 8 eyes with short posterior ciliary artery and 35 eyes with reduced background fluorescence , Choroidal neovascularization in 8 eyes, lacquer-like cracks in 52 eyes. Conclusion The imaging features of FFA and ICGA examination in high myopia are mainly manifested as the decrease of background fluorescence, lacquer-like crack and choroidal neovascularization. FFA and ICGA simultaneous examination can more fully understand the high myopia retinal and choroidal fundus pathological changes, help to fully understand the disease and guide further treatment.
