泪液代用品“干眼灵”临床观察

局部滴用“干眼灵”滴眼剂治疗干眼症,用药后病人症状明显改善,其角膜前泪膜保留时间平均为25.818分钟,泪膜破裂时间(BUT)平均为31.363秒,对泪河宽度及泪液分泌试验(Schirmer's test)无明显影响。临床资料提示“干眼灵”滴眼剂可作为泪液代用品治疗干眼症。     

干眼病的药物治疗进展

干眼病是泪液量或质异常的一大类疾病。传统治疗方法有补充人工泪液、泪液保持、促进泪液分泌三大方面。近年来,随着对眼表免疫机制、性激素作用机制的深入研究,针对干眼病潜在病因的治疗有了新的进展。     

干眼病不能一滴眼药水了之

冬季过于干燥的天气让人感到嗓子干痛、眼睛干涩，一些老年人除了眼睛干涩外，眼睛还觉得容易疲劳，视力下降，有异物感甚至有刺痛感等，这是什么原因呢？原来是由于在冬季天气干燥，使泪液的蒸发加速而成为“干眼病”的诱因之一。这个季节，干眼病的患者明显增加，估计干眼病患者占眼科门诊患者的10％～20％的比例，而在我的专家门诊中此类患者更是接近70％。专家提醒，冬季干燥应预防干眼病。     

环戊硫酮治疗干眼的临床疗效评价

Objective To investigate anethol trithione therapic efficiency on dry eye. Methods It was a prospective random double-blind controlled study. Eighty cases diagnosed dry eye in Ocular Surface Out-patient Clinic of Xiamen University Affiliated Xiamen Eye Center from 2006 to 2008 were divided into two groups: anethol trithione group and control group, 40 cases in each group. Every group was then divided into two subgroups: weak dry eye subgroup, middle and severe dry eye subgroup. All groups had been added with 0.05% refresh drops. All patients had been detected and evaluated by subjective symptoms of dry eye, visual acuity,corneal fluorescent staining(F1), break-up time(BUT) and Schirmer Ⅰ test (SⅠT) at pre-therapy and 3,7,28 d of post-therapy. All groups had been compared and analyzed by F test and sample mean difference (SMD) or median difference (MD) comparison between pre-therapy and post-therapy. Results Except of tear and red eye, the other subjective symptoms of dry eye, F1, BUT and SⅠT of weak dry eye subgroup of both groups had been improved at 7 d after therapy. Only those of middle and severe dry eye subgroup of anethol trithione group had been improved at 7 d after therapy compared with those of pre-therapy: SMD=0.96 (visual tiredness), 1.26 (dry and unsmooth sensation), 0.82 (foreign body sensation), 1.28 (burning sensation), 1.05 (photophobia), 1.48 ( pain ) ; MD=0.30 (visual acuity), 4.00 (F1) ,5.00 (BUT), 5.00 (SⅠT) [F=15.30 (visual tiredness), 15.68 (dry and unsmooth sensation ), 13.56 (foreign body sensation), 20. 91 ( burning sensation ), 18.90 (photophobia), 27.22 ( pain ), 10.54 (visual acuity), 188.21 (F1) ,261.76 (BUT) ,269.05 (SⅠT) ;P<0. 05]. Those of middle and severe dry eye subgroup of control group hadn't significantly been improved at 28 d after therapy: SMD=0.10 (visual tiredness) ,0.16 (dry and unsmooth sensation) ,0.09 (foreign body sensation) ,0.38 ( burning sensation ), 0.24(photophobia) ,0.36 (pain) ,0.23 (red eye) ; MD=0.10 (visual acuity) ,0.50(F1) ,0.50(BUT), 0.50(SⅠT) [F=1.76 (visual tiredness), 1.61 (dry and unsmooth sensation), 1.02 (foreign body sensation),2.39 (burning sensation), 2.42 (photophobia), 2.73 ( pain ), 2.55 ( red eye ), 1.46 ( visual acuity) ,2.35 (F1) ,2.90 (BUT) ,2.76 (SⅠT) ; P>0.05]. SⅠT of anethol trithione group had been improved more significantly after therapy (F=13.77, P<0.05). Conclusion Anethol trithione could significantly improve middle and severe dry eye patients' symptoms and signs whose lacrimal gland function survival and it has clinical application value.     

干眼病患者红细胞和淋巴细胞免疫功能对比研究

本文对４８例干眼病患者的红细胞免疫和Ｔ淋巴细胞免疫功能进行了测定和对比研究。红细胞Ｃ３ｂ受体花环率均值为６．９８±３．１２％，红细胞免疫复合物花环率均值为８．１２±３．５３％，对照组分别为１２．８０±５．３５％和５．２０±１．１５％，二项均有显著性差异（Ｐ≤０．０１）。Ｔ细胞亚群均值为：ＣＤ３５８．１２±４．７６％，ＣＤ４３８．９２±３．９２％，ＣＤ８３７．５８±５．６１％，ＣＤ４／ＣＤ８＝１．０３±０．６９，对照组分别为６７．９８±５．８０％，４５．４２±５．２４％，２９．２４±３．０２％，１．５５±１．７３，各项均有显著性差异（Ｐ≤０．０１）。结果表明，干眼病患者的红细胞免疫功能和Ｔ淋巴细胞亚群均异常，且两者呈一致性关系，机体免疫调节机制紊乱。     

Keratograph眼表综合分析仪对高度近视患者眼表功能的评估

目的:通过Keratograph眼表综合分析仪和眼表疾病指数(OSDI)问卷调查评分分析高度近视患者干眼和眼表状况。方法:选取高度近视患者35例(70眼)为高度近视组,同期31例(62只眼)非高度近视患者为非高度近视组;分别进行OSDI问卷调查及Keratograph 5M眼表综合分析仪检查。记录泪河高度、泪膜首次破裂时间(NITBUTf)、泪膜平均破裂时间(NITBUTav)、脂质层厚度分级、睑板腺缺失程度、角膜荧光染色评分。结果:OSDI检测出高度近视组干眼患病率(54.29%),明显高于非高度近视组的干眼患病率(19.34%)(P<0.05);Keratograph 5M眼表分析仪检测高度近视患者干眼患病率(54.29%),高于非高度近视患者患病率(29.03%)(P<0.05)。高度近视组和非高度近视组泪河高度均在正常范围内(泪河高度>0.20mm)。高度近视组与非高度近视组相比,NITBUTf、NITBUTav缩短,睑板腺完整度的评分下降,角膜荧光素染色评分较高,差异均具有统计学意义(P均<0.05)。结论:Keratograph眼表综合分析仪可以客观、精确地用于评估高度近视患者泪膜的功能变化,这类患者是干眼的高发人群,要重视其防治。     

润目地黄汤治疗干眼症35例70只眼临床观察

干眼症是最常见的眼科疾病之一，是由多种原因导致泪膜的病理性改变，使角膜和结膜得不到正常的湿润而发生眼表上皮干涩的一组疾病的总称。除局部有刺激症状外，还可引起视物模糊或视力波动等，严重者可致视力严重下降，甚至失明。我国目前干眼症有很高的发病率，然而至今尚无特效疗法，临床治疗颇为棘手。笔者采用润目地黄汤治疗35例70只眼干眼症患者，取得较好疗效，并与用西药治疗的35例70只跟作对照观察，总结如下。
