目的探讨前部缺血性视神经病变的发生因素及诊断。方法回顾性分析前部缺血性视神经病变 95例 (10 3只眼 )的发病特点 ,以及视野和眼底荧光素血管造影的表现。结果平均发病年龄 5 2 .4岁。 8例 (10只眼 )无原发病 ,87例 (93只眼 )伴有糖尿病、高血压和 (或 )眼底动脉硬化。眼底荧光素血管造影早期视盘全部或部分荧光充盈延缓或缺损 ,伴有相应的视野缺损。造影晚期视盘荧光形态有多种表现形式 ,缺血区呈强荧光者 76只眼(73 .79% ) ,呈弱荧光者 2 7只眼 (2 6 .2 1% )。结论中老年的糖尿病、高血压和 (或 )动脉硬化患者是前部缺血性视神经病变的高危人群 ,其诊断应综合考虑临床症状、视野和眼底荧光素血管造影检查结果。
Objective To investigate the occurrence and diagnosis of anterior ischemic optic neuropathy. Methods The clinical features of 95 cases (103 eyes) of anterior ischemic optic neuropathy were retrospectively analyzed, as well as the visual field and fundus fluorescein angiography. Results The average age of onset was 52.4 years. Eight patients (10 eyes) had no primary disease, and 87 patients (93 eyes) had diabetes, hypertension and / or fundus arteriosclerosis. Fundus fluorescein angiography early or full partial or partial fluoroscopic filling delay or defect, accompanied by the corresponding visual field defects. There are many manifestations of late-stage optic disc fluorescence morphology in 76 cases with strong fluorescence in the ischemic area (73.79%) and 27 eyes (26.21%) with weak fluorescence. Conclusions Middle-aged and elderly patients with diabetes, hypertension and atherosclerosis who are at high risk for anterior ischemic optic neuropathy should be diagnosed with clinical symptoms, visual field and fundus fluorescein angiography.
