应用荧光素眼底血管造影(fluoresceinfundusangiogra-phy,FFA)的方法研究前部缺血性视神经病变(anteriorischemicopticneuropathy,AION),使人们对AION的临床特点、病因和发病机制的认识逐渐加深。然而,AION的FFA视盘荧光形态很复杂,依据病期长短,是部分还是全部视盘梗塞,是否累 The study of anterior ischemic optic neuropathy (AION) by means of fluorescein fundus angiography (FFA) has gradually deepen the understanding of the clinical features, etiology and pathogenesis of AION. However, AION FFA optic disc fluorescence patterns are complex, depending on the length of the disease, is part or all of the optic disc infarction, is tired
