摘 要:目的观察降眼压治疗对非动脉炎性前部缺血性视神经病变(NA10N)眼部血流动力学的影响。方法lI缶床确诊为NAION的68例患者68只眼纳入研究。采用随机数字表法将患者随机分为眼压干预组及对照组,分别为38例38只眼、30例30只眼。所有患者常规行甲基强的松龙200mg3d冲击治疗,静脉滴注血栓通注射液300mg扩血管治疗,鼠神经生长因子30弘g视神经营养治疗及颞侧穴位注射复方樟柳碱2m1。总疗程10d。眼压干预组在此基础上采用噻吗心胺滴眼液及布林佐胺滴眼液滴眼降低患者眼压至≥8mmHg(1mmHg=0.133kPa)或降低眼压程度≥30%。对照组不作任何降眼压处理。治疗前后两组患眼行彩色多普勒超声血流成像检查,对比分析治疗前后两组眼动脉(OA)、视网膜中央动脉(CRA)及睫状后短动脉(PCA)的收缩期峰值血流速度(PSV)、搏动指数(PI)及阻力指数(RI)变化。结果治疗前,眼压干预组及对照组0A、CRA及PCA的PSV(t=1.023、1.145、0.569)、PI(t=0.679、0.956、1.634)及RI(t=0.816、1.657、0.998)比较,差异均无统计学意义(P〉0.05)。与治疗前比较,治疗后眼压干预组OA、CRA及PCA的PSV(t=3.150、7.650、3.520)、PI(t=2.420、5.430、7.650)明显增加,差异有统计学意义(P〈O.05);RI(t=5.320、9.640、18.360)明显降低,差异有统计学意义(P〈O.05)。与治疗前比较,治疗后对照组()A、CRA及PCA的PSV(t=2.090、-2.550、-2.100)、PI(t=-2.310、-2.230、-4.490)有所增加,差异有统计学意义(P〈0.05);RI(t=2.970、2.160、2.690)有所降低,差异有统计学意义(P〈0.05)。治疗后,眼压干预组0A、CRA及PCA的PSV(t=2.632、2.135、5.364)、PI(t=3.251、2.432、4.243)均较对照组明显增加,差异有统计学意义(P%0.05);RI(t=3.664、2.938�Objective To observe the effect of lowering intraocular pressure(IOP) treatment on ocular hemodynamics in patients with nonarteritic anterior ischemie optic neuropathy (NAION). Methods A total of 68 patients with NAION (68 eyes) were enrolled in this study. The patients were randomly divided into treatment group (38 eyes of 38 patients) and control group (30 eyes of 30 patients). All the patients were received methylprednisolone pulse therapy (200 mg, three days), vasodilator therapy with intravenous infusion of Xueshuantong solution (300 mg), optic nerve nutritional therapy with mouse nerve growth factor (30 μg) and acupoint injection in temporal with compound anisodine (2 ml). The total course was 10 days. The patients of treatment group received IOP lowering treatment to reduce the IOP to 〉 8 mm Hg (1 mm Hg=0. 133 kPa) or in a 30% reduction, The patients of control group received no IOP lowering treatment. The peak systolic velocity (PSV), pulsatility index (PI) and resistance index (RI) of ophthalmic artery (OA), central retinal artery (CRA) and short posterior ciliary arteries (PCA) before and after treatment were comparatively analyzed by color doppler flow imaging. Results The differences of PSV (t= 1. 023, 1. 145, 0. 569), PI (t=0. 679, 0. 956, 1. 634) and RI (t=0. 816, 1. 657, 0. 998) of OA, CRA and PCA before treatment in treatment group and control group were not statistically significant (P〈0.05). Compared with before treatment, PSV (t=3.150, 7. 650, 3. 520) and PI (t=2.420, 5. 430, 7. 650) of OA, CRA and PCA increased obviously (P〈0.05), RI of OA, CRA and PCA decreased obviously (t= 5. 320, 9. 640, 18. 360; P〈0.05) after treatment in treatment group. In control group, the differences ofPSV (t=2.090, --2.550, --2.100) and PI (t=--2.310, --2.230, -4.490) of OA, CRA and PCA between before and after treatment were not statistically significant (P〈0.05) ; but the differences of RI of OA,
