本文通过眼底荧光血管造影(FFA)对前部缺血性视神经病变66例(74眼)的造影图像进行分析。结果表明:造影早期视盘缺血区均呈弱荧光,显示缺血累及的部位和范围,伴随相应的视野缺损。造影晚期视盘荧光形态各异,其中主要表现为强荧光者67眼(90.54%),多见于病程早期;视盘仍呈弱荧光者7眼(9.46%),见于病程较长者。认为FFA是本病诊断的重要依据,但应参照临床症状、眼底和视野等资料综合分析才能有利于准确确诊。
In this study, 66 cases of anterior ischemic optic neuropathy (74 eyes) were analyzed by fundus fluorescein angiography (FFA). The results showed that: early ischemic optic disc imaging showed weak fluorescence, showing the location and extent of ischemia, accompanied by the corresponding visual field defects. The fluorescence patterns of the late optic disc were different. Among them, 67 eyes (90.54%) had strong fluorescence, which was more common in early stage of disease; 7 eyes (9.46%) were still weak in optic disc. FFA is considered an important basis for the diagnosis of this disease, but should be based on clinical symptoms, fundus and visual field and other comprehensive analysis of information can be conducive to accurate diagnosis.
