目的探讨缺血性视神经病变的易患因素、临床特征、治疗及预防。方法回顾性分析64例67眼缺血性视神经病变的发病年龄、局部及全身存在的易患因素、临床特点及治疗体会。结果 60岁以上的患者52例(81.25%);男∶女=9∶7;单眼61例(95.31%)、双眼3例(4.69%);47例(73.44%)患者并存高血压、糖尿病、高血脂症,17例(26.56%)患者无全身疾病,但存在小视盘,无生理凹或小生理凹;且多为早晨起床后发现视野、视力有所改变。眼底荧光血管造影(FFA)检查:早期视盘部分或大部分呈弱荧光,晚期视盘呈强荧光或弱荧光。经临床治疗,视力有所提高者23眼(34.33%),视野有所改善者20眼(29.85%)。结论缺血性视神经病变发病受年龄、全身性易患因素及局部解剖因素的影响,眼底、视野、FFA等检查有其典型特征,治疗效果欠佳,为减少该病的患病率,应对易患人群进行早期干预性治疗。
Objective To investigate the predisposing factors, clinical features, treatment and prevention of ischemic optic neuropathy. Methods A retrospective analysis of 64 cases of ischemic optic neuropathy in 67 eyes of the age of onset, local and systemic risk factors, clinical features and treatment experience. Results There were 52 (81.25%) patients aged 60 and older; male and female 9: 7; 61 eyes (95.31%) were monocular, 3 eyes (4.69%) were eyes and 47 (73.44% Hyperlipidemia, 17 cases (26.56%) patients without systemic disease, but the presence of small video disc, no physiological concave or small physiological concave; and mostly found in the morning after vision, visual acuity changed. Fundus fluorescein angiography (FFA) examination: Early or most of the optic disc was weak fluorescence, late optic disc showed strong fluorescence or weak fluorescence. After clinical treatment, 23 eyes (34.33%) had visual acuity improvement and 20 eyes (29.85%) had visual field improvement. Conclusion The incidence of ischemic optic neuropathy is affected by age, generalized predisposing factors and local anatomical factors. The fundus, visual field, FFA and other tests have their typical features, the treatment effect is not good. In order to reduce the prevalence of the disease, People suffering from early intervention therapy.
