简介：探讨特殊人群前葡萄膜炎的治疗方法。方法针对全身应用激素治疗受限制的特殊人群,应用散瞳、局部肾上腺皮质激素的应用及热敷等局部治疗方法,对43例前葡萄膜炎的治疗效果进行临床总结。结果43例特殊人群前葡萄膜炎全部临床治愈。结论特殊人群前葡萄膜炎应用局部治疗,方法简单,疗效可靠,与全身应用激素治疗的一般葡萄膜炎病例无明显差异,能避免葡萄膜炎格式化的静脉滴注和大剂量的激素治疗误区。

简介：目的：通过分析细胞因子的性质，旨在探讨前葡萄膜炎可能的发病机制。方法：取20例HLA-B27相关前葡萄膜炎患者、20例小柳原田患者外周血和正常人作为对照组，通过酶联免疫反应（ELISA）检测患者外周血IFN-γ，IL-4和IL-10的含量。结果：两组患者外周血IFN-γ的含量较正常人显著增高（P〈0．05），且小柳原田患者外周血中IFN-γ含量显著高于HLA-B27相关前葡萄膜炎患者外周血中IFN-γ含量（P〈0．05）。结论：前葡萄膜炎发病机制可能和对自身抗原诱发的Th1型免疫反应过强有关。

简介：<正>白内障囊外摘除及人工晶体植入,术后常发生不同程度的炎症反应,这些反应经过药物治疗,多数在术后1～2周内逐渐消退和消失。但也有炎症消退后突然又复发,甚至导致严重葡萄膜炎而致眼球萎缩。我们曾遇到4例,现报告如下。

简介：目的：探讨糖皮质激素治疗角膜葡萄膜炎的方法。方法：对27例27眼角膜葡萄膜炎患者采取抗感染药物联合应用微小剂量糖皮质激素治疗,观察疗效并评价其安全性。结果：全部病例经上述治疗后均得到治愈,无药物并发症发生。结论：微小剂量糖皮质激素应用于角膜葡萄膜炎的治疗是一种有效、安全、实用性较好的方法。

简介：目的：评价超声乳化术治疗葡萄膜炎并发白内障的治疗效果。方法：回顾分析40例48眼葡萄膜炎并发性白内障患者超声乳化手术治疗前后的情况。结果：术后2wk有44眼（92％）视力较术前提高；术中5眼（10％）计划外后囊破裂，6眼（13％）发生虹膜出血；术后第2d角膜水肿38眼（79％），前房渗出43眼（90％），5眼（10％）术后眼压增高，12眼（25％）瞳孔欠圆。结论：超声乳化术治疗葡萄膜炎并发白内障相对较复杂，并发症较多，但整体效果良好。

简介：目的探讨前葡萄膜炎并发白色白内障超声乳化吸除术治疗的临床效果。方法选取我院2013年8月~2015年8月确诊为并发性白色白内障患者15例24眼行超声乳化吸除联合人工晶状体植入术治疗,虹膜后粘连范围广泛采用23G玻切环切虹膜缘瞳孔再造,每例均行前囊膜染色。术后观察视力、眼压、瞳孔对光反应、前房炎症反应、并发症及葡萄膜炎复发情况。结果24眼术后视力均有不同程度提高,1w后脱残率87.5%,6m脱残率92.7%。瞳孔恢复灵敏对光反应8眼,对光反应迟钝10眼,并发症包括后发性白内障1眼（0.04%）,轻微虹膜后粘连眼3眼（12.5%）,一过性高眼压眼3眼（12.5%）,术后未见葡萄膜炎复发。结论前葡萄膜炎并发白色白内障常常伴随虹膜粘连,晶体全白膨胀,手术复杂,但选好手术时机熟练掌握手术方法,超声乳化吸除术安全可靠,视力恢复好。

简介：目的探讨葡萄膜炎并发白内障晶状体超声乳化吸出及人工晶状体植入术的疗效。方法对38例38眼葡萄膜炎并发白内障患者行晶状体超声乳化吸出及人工晶状体植入术。结果38眼术后裸眼视力均有不同程度的提高。术后3月≥0.5者31眼（80.77%）,0.3～0.4者3眼（7.69%）,0.1～0.2者2眼（5.77%）,〈0.1者2眼（5.77%）。结论晶状体超声乳化吸出术治疗葡萄膜炎并发白内障,术前充分准备,术中、术后处理得当,则术后炎症反应轻,视力恢复好。

简介：目的探讨非穿透性小梁手术（nonpenetratingtrabecularsurgery，NPTS）对葡萄膜巩膜房水流出量的影响，从房水动力学的角度揭示NPTS降眼压的机制。方法用示踪剂异硫氰酸荧光素牛血清白蛋白（fluoresceinisothiocyanate—bovineserumalbumin：FITC—BSA）于术后7d分别对手术后的兔眼模型组和正常兔眼组进行前房持续灌注30min，灌注毕处死家兔，摘除双侧眼球，并将组织分离为前巩膜、后巩膜、前葡萄膜、后葡萄膜、视网膜和残余液体等6种组织。测定每种组织的荧光强度，计算葡萄膜巩膜流出量（uveoscleraloutflow，Fu）。结果实验组葡萄膜巩膜流出量明显高于正常组，两组前房水再现量均以前葡萄膜、前巩膜和残余液体为多，实验组术后葡萄膜巩膜通道各组织房水再现量与正常组相比差异有统计学意义（p〈0．001）。结论非穿透性小梁手术能增加葡萄膜巩膜途径房水流出量，房水主要由前巩膜排出。

简介：青光眼是全球第二大致盲眼病,是不可逆性盲最主要原因,而原发性闭角型青光眼（primaryangleclosure[1]glaucoma,PACG）是我国最主要的青光眼类型。原发性闭角型青光眼（PACG）的发病机制复杂。PACG发病的主要危险因素是晶状体位置偏前、前房变浅而导致的瞳孔阻滞。此外,周边虹膜肥厚以及睫状体位置前移也是PACG发病的常见危险因素。

简介：目的分析常年性变应性鼻炎的狗、猫上皮变应原皮肤点刺试验的阳性结果，对其他气传变应原的反应性，并进一步探讨环境接触与其相关性。方法总结1022例常年性变应性鼻炎患者采用阿罗格叶7种气传变应原标准化试液进行的皮肤点刺试验；分析狗、猫上皮变应原的皮试结果及合并其他气传变应原阳性的比例；并根据是否有环境接触分类，比较各组在阳性率分布上的差异。结果常年性变应性鼻炎中狗上皮变应原皮试阳性占13．80％，猫上皮阳性占6．95％；且98％以上合并其他气传变应原阳性，尤以合并粉尘螨、屋尘螨阳性居多。其中21．93％和26．32％环境接触狗／猫的变应性鼻炎相应狗／猫上皮变应原皮试阳性；无环境接触组的阳性率分别为12．78％和6．58％，差异均有统计学意义（P〈0．01）。结论常年性变应性鼻炎的狗上皮及猫上皮的阳性率位居前列，其中绝大多数合并其他气传变应原阳性。鉴于环境接触对狗、猫上皮过敏的高危险性，变应性鼻炎患者应该尽可能地避免饲养、接触宠物。
