【摘要】 目的 观察分析23例(35眼)急性前部缺血性视神经病变的眼底荧光造影(FFA)图像表现特点。方法 收集本院做过FFA检查的视盘水肿病例分为两组进行回顾性、对比性分析。Ⅰ组为确诊急性前部缺血性视神经病变患者，Ⅱ组包括急性视乳头炎、视乳头水肿、视盘血管炎的视盘水肿患者。结合视野检查，部分患者做头颅CT或MR检查。重点关注Ⅰ组急性前部缺血性视神经病变病例。结果 (1)FFA资料:Ⅰ组病例35眼(100%)在造影早期视盘均呈弱荧光，造影后期视盘呈强荧光或强弱荧光不对称，形态比较复杂。视盘荧光染料渗漏显现时间Ⅰ组(静脉期后20～45s)较Ⅱ组(动脉早期10～20s)明显延长。经统计学处理，差异有显著性(P<0.05)。造影早期视盘周脉络膜弱荧光28眼，两组发生比率差异有非常显著性(P<0.01)。(2)视野资料:26眼视野检查，20眼荧光图像与视野缺损呈对应关系，3例未出现相应现象，3例出现相反现象。其中下部半盲5眼，扇型或象限性缺损21眼。结论 造影早期视盘呈弱荧光，造影后期视盘呈强荧光或强弱不对称是急性前部缺血性视神经病变的FFA图像特征。FFA检查对急性前部缺血性视神经病变有较高诊断价值，结合病史、症状、视野检查常能获得早期的诊断。
