简介：患女，3岁。家长发现其右眼内有白色球状物质。外院诊断为“右眼玻璃体积血”。家长否认患儿既往有眼病和外伤史，否认全身其他系统严重的器质性疾病。眼科检查：右眼眼压Tn＋1。眶缘光滑，未扪及肿物。角膜透明，色素性KP（＋）。前房深浅正常，下方见数枚球形白色物质，直径约1～2min。虹膜表面新生血管。瞳孔散大，直径约6min，对光反应迟钝，

简介：目的探讨不同程度眼外伤前房积血的综合治疗。方法回顾性分析我院2007年1月至2010年10月收治的47例外伤性前房积血临床资料。结果Ⅰ级和Ⅱ级外伤性前房积血无再出血和其他并发症者恢复顺利,预后良好,Ⅲ级以上外伤性前房积血,或合并有再出血或其他并发症者恢复慢,预后不良。结论采取及时、合理的药物治疗,把握恰当的手术时机、选择正确的手术方法,促进积血吸收,防止再出血和并发症的发生是治疗的关键。

简介：患者男性，56岁。2009年8月20日因用力吹气球，当日出现左眼无痛性视力下降，9月23日就诊于我院眼科门诊。既往史、家族史无特殊。全身检查无异常。右眼视力1．0，左眼视力手动／眼前，矫正不能提高。双眼结膜无充血，角膜透明，前房深度正常，瞳孔圆，对光反射正常。双眼晶状体轻度混浊，左眼玻璃体积血，视网膜无法窥见，右眼眼底无异常。

简介：目的：探讨人工晶状体眼老视的科学检测方法。方法：随机抽取年龄在40～75岁之间“白内障超声乳化＋人工晶状体植入”术后老视患者80例（118眼）从术后1wk开始随访6mo以上，检测角膜散光度数变化，并根据患者的阅读需要和距离进行客观和主观验光。结果：白内障术后角膜散光1wk～1mo的平均度数与术前比较差异有显著性（P〈0．01），3mo的角膜散光与术前比较差异无显著性，白内障人工晶状体眼的老视近附加3个年龄组间比较差异无统计学意义。结论：白内障术后人工晶状体眼的近附加验配不随年龄的增加而增加，应待角膜散光稳定后根据被测的调节参数进行精确的验配，而不能简单地按照经验公式开出处方。

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：观察链脲佐菌素（STZ）诱发糖尿病大鼠在造模后血-视网膜屏障（blood—retinabarrier，BRB）变化情况，并以阳性药为对照研究中药芪灯明目胶囊对STZ诱发糖尿病大鼠的视网膜血管渗漏影响。方法：采用STZ腹腔注射制作糖尿病大鼠模型，在造模后6too内各时点（2wk；1，2，3，4，5，6mo）采用伊文思蓝灌注示踪显示血一视网膜的渗漏情况，在造模后3too开始用中药芪灯明目胶囊（低中高剂量组分别给予125，250，500mg／kg体质量剂量的胶囊内容物灌胃），对照组用安多明胶囊（200mg／kg体质量剂量，相当于10倍成人剂量），灌胃3mo，观察药物对BRB的影响。结果：STZ糖尿病大鼠在2wk即可出现BRB的损害，并随着高血糖状态的持续而不断加重。对造模3tooSTZ糖尿病模型大鼠连续灌胃中药芪灯治疗3mo，结果提示：中药芪灯对STZ糖尿病BRB有保护作用，可明显减少视网膜血管的渗漏。结论：STZ糖尿病模型大鼠在早期即可出现BRB损害，并随着高血糖的持续而加重，中药芪灯明目胶囊可减少高血糖导致的BRB损害。

简介：目的探讨角膜隧道切口前房冲洗术治疗创伤性前房积血的疗效和临床价值。方法对我院自2005年1月至2010年6月收治27例严重创伤性前房积血患者行角膜隧道切口前房冲洗术。观察术中并发症,术后视力,眼压。结果27例均一次清除完前房积血,无术中并发症,术中虹膜无脱出。术后随访6月,矫正视力0.8以上者7例,0.3-0.8者16例,0.05-0.3有4例,23例低于21mmHg。结论角膜隧道切口前房冲洗术操作简单,手术损伤小,是安全有效的手术方法。

简介：目的研究高纤维蛋白原血症在突发性耳聋发病中的作用.方法40例诊断明确、发病在7d以内的患者为研究对象(共49只耳),42例正常健康人作为对照组,分别对其血液流变学、血生化、全血细胞计数、凝血功能作检测,检测结果输入SPSS软件作处理进行统计学分析.结果突发性耳聋患者纤维蛋白原水平、红细胞聚集指数、血浆粘度明显高于对照组;差异有显著统计学意义(P＜0.05),血浆凝血酶原时间、白陶土部分凝血活酶时间明显短于对照组,差异也有显著统计学意义(P＜0.05),血生化和全血细胞计数无明显统计学意义(P＞0.05).结论血浆纤维蛋白原水平的提高可能是突发性耳聋血管性病因中的主要因素.

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。
