Abstract Background Loss of retinal ganglion cells(RGCs)is a dominant feature of optic nerve in glaucoma.Our previous study showed that traditional Chinese herbs have a neuoprotective effect on RGCs. Objective This study was to evaluate the protective effect of yiyanming on optic nerve in glaucoma patient after controlled intraocular pressure(IOP). Methods Fifty—two patients(101 eyes)suffered from primary open—angle glaucoma with visual field defect and IOP less than 1 8 mmHg were enrolled in this survey.The patients were randomly assigned to the therapeutic group(n=53)and the control group(n=48).Yiyanming solution 10 mL was administered orally three times per day for 12 weeks associated with the topical administration of in therapeutic group,and only was topically administered in the control group.The therapeutic effects of Yiyanming solution were assessed before treatment and at the end of the first,second,third month after treatment respectively.The changes of visual acuity,fundus and the mean defect(MD),mean sensitivity(MS)and 1 OSS variance(LV)of perimetry were observed.Written informed consent was obtained from the patients at the initial of this tria1. Results No obvious changes were found in visual acuity and fundus in all patients after administration of Yiyanming in both groups.In the 4th week after treatment, the MS value was significantly elevated(t=4.009,P=0.000),but the MD value was declined(t=一2.587,P=0.013)in comparison with before treatment.In the 8th week after treatment,the MS value was considerably increased(t=4.009,P=0.000), but the MD and LV values were decreased(t=一3.874,P=0.000;t=一2.868,P=0.O06)in comparison with before treatment in Yiyanming group The rise of MS value.decline of MD and LV were statistically different after treatment versus before treatment(t= 5.086,P=0.000;t=一2.580,P=0.013;t=一2.765,P=0.008)at the 12nd week in the therapeutic group. Conclusion Yiyanming oral solution may have protective effect on visual function of primary glaucoma with controlable IOP in some extent.

摘要 目的探讨益眼明151服液对眼压已控制的青光眼患者视神经的保护作用。方法选择有视野缺损、眼压控 制在≤18 mmHg的原发性开角型青光眼患者52例101眼,随机分为试验组27例53眼和对照组25例48眼。对照组仅 用噻吗心胺滴眼液点眼,试验组同时应用噻吗心胺滴眼液点眼及益眼明口服液每日3次口服,连续用药12周;观察用药 前后视力、眼底的变化,分别于用药后4、8、l2周检测视野平均敏感度(MS)、平均缺损值(MD)和丢失方差(LV)等指标, 并与其术前值进行比较。 结果 用药前后各时间点试验组和对照组视力及眼底均未见明显改变。试验组用药4周后 患者视野MS值明显高于用药前,差异有统计学意义(t=4.009,P=0.000);MD值明显低于用药前,差异有统计学意义 (t=一2.587,P=0.013)。用药后8周,患者视野MS值明显高于用药前值,差异有统计学意义(t=8.848,P=0.000); MD和LV值明显下降,差异均有统计学意义(t=一3.874,P=0.000;t=一2.868,P=0.006)。试验组用药l2周后,MS 值的升高、MD与LV的下降与用药前比较差异均有统计学意义(t=5.086,P=0.000;t=一2.580,P=0.013;t=一2.765, P:0.008)。结论益眼明13服液对原发性开角型青光眼患者的视神经有一定程度的保护作用。 关键词 中药/益眼明口服液;原发性青光眼;视神经 中图分类号R 775.05文献标志码A 

青光眼是常见的不可逆性致盲性眼病之一,世界 DOI:10.3969/j.issn.1003 ̄808.2010.11.019 作者单位:510120广州,广东省中医院眼科 通讯作者:王燕(Email:wangyan96000@126.tom) 

卫生组织已将青光眼列为第二位致盲性眼病。研究表 明,细胞凋亡是导致青光眼视网膜神经节细胞(retinal ganglion cells,RGCs)进行性减少的主要机制之一…, 

因此,除降低眼压外,对抗RGCs的凋亡和保护视神经 成为青光眼防治的主要课题。近年来,中药在治疗青 光眼RGCs进行性减少保护方面的研究中具有独特的 优势,可以有效地改善青光眼患者的视功能 -31。为 了进一步开发对视神经有保护作用的中药,本研究采 用益眼明口服液对眼压已控制的原发性开角型青光眼 患者进行前瞻性、随机分组研究,客观地评价其对青光 眼患者视功能的保护作用。 1资料与方法 1.1一般资料 收集2006--2008年广东省中医院眼科诊断为原 发性开角型青光眼且眼压已控制在≤18 mmHg (1 mmHg=0.133 kPa)的患者52例101眼,病程2~5 年。将52例101眼随机单盲法分为试验组27例53 眼,其中男l1例,女16例;平均年龄62岁。对照组25 例48眼,其中男10例,女15例;平均年龄61岁。2组 患者病程、原治疗方法、眼压程度、眼底检查、视野损害 程度基本匹配。纳入标准:(1)原发性开角型青光眼 局部应用降眼压药物(噻吗心胺或贝他根滴眼液,每 日2次,每次1滴)眼压可控制者。(2)非接触眼压计 测量眼压每次均≤18 mmHg。(3)矫正视力/>0.1,符 合中晚期青光眼视野改变的原发性开角型青光眼患 者。排除标准:(1)原发性开角型青光眼合并有糖尿 病视网膜病变(diabetic retinopathy,DR)及其他眼底病 变或视神经疾病者。(2)原发性开角型青光眼合并有 心血管系统、神经系统等全身疾病并长期服用扩张血 管、改善血液循环的中西药物治疗者。所有患者进入 试验前均签署知情同意书。 1.2方法 试验组局部点用噻吗心胺或贝他根滴眼液,同时 口服中成药益眼明口服液(广东省中医院研制),每日 3次,每次10 mL,连续服用l2周;对照组仅局部点用 噻吗心胺滴眼液,不服用其他任何药物。分别用国际 标准视力表观察患者服药前及服药后4、8、l2周的视 力,同时检查眼底和视野。其中视野检查采用Octopus 101型全自动视野计(瑞士Interzeg公司),有屈光不正 或老视者均用镜片矫正后进行检查,检测背景光 4 asb,选用Ⅲ型光标,光标持续时间100 ms,将检查结 果存人电脑并打印。主要观察视野的平均缺损(mean defect,MD)值、平均敏感度(mean sensitivity,MS)、丢 失方差(1oss variance LV)、可靠性因素(reliability factor,RF),RF>15%者不纳入统计。 1.3统计学方法 采用SPSS 10.0统计学软件对数据进行统计分 析。试验测试指标均以 ±s表示,各组内试验前后视 野MS、MD、LV值的差异比较均采用配对t检验。P< 0.05为差异有统计学意义。
