摘要
目的 :探讨非动脉炎性前部缺血性视神经病变 (nonarteriticanteriorischemicopticneuropathy ,NAION)中视盘水肿程度、缺血部位对中心视力的影响 ,以利于疗效评定及预后判断。方法 :2 40例NAION患者 (160例接受住院治疗 )的临床资料 ,结合视野和荧光眼底血管造影 (fundusfluoresceinangiography ,FFA)检查进行治疗前中心视力与水肿程度、缺血部位两方面统计分析 ,并分析治疗效果。结果 :2 40例NAION患者发病时中心视力的损害程度 ,依视盘缺血部位、水肿程度之不同而均有显著的差异 (P <0 0 0 5 )。 160例住院患者 ,视盘水肿消退时间最长为 3 5天 ,最短 11天 ,平均时间 2 1 5天 ,FFA复查四项指标改善率 88 1% ,中心视力两行行上者 10 4例 ,占 65 %。结论 :视盘的缺血部位及水肿程度是影响NAION中心视力的重要因素之一 ,积极针对性的治疗对防止NAION致盲有重要意义。
Objective:To investigate the impacts on visual acuity of the edema at optic disc and ischemic area in nonarteritic anterior ischemic optic neuropathy (NAION). Methods:240 cases of NAION with the edema at optic disc were analyzed on visual acuity,optic disc ischemia,edema status,and fundus fluorescein angiography (FFA). Results:The visual acuities at onset time of 240 cases of NAION were significantly different depended on the edema status at optic disc and the ischemic area (P<0 005).In 160 in-patient cases,after treatment,the longest diminished time of optic disc edema was 35 days,the shortest 11 days (means 21 5 days).The visual acuity improved in 104 patients (65%). Conclusions:The results show that ischemic area and edema at optic disc are the important factors for the visual acuity of NAION.
