简介：手法小切口白内障术（manualsmallincisioncataractsurgepy，MSICS）特别是在发展中国家已广泛应用于临床手术。本文旨在比较传统白内障囊外摘除术（extracapsularcataractextraction，ECCE）、MSICS以及超声乳化白内障吸除术治疗效果以及安全性（术中并发症以及术后并发症）。通过使用PubMed搜索引擎，我们收集了传统ECCE、MSICS以及超声乳化白内障吸除术的相关文献，以评价其安全性和治疗效果。同时，也参考了国内出版的相关文献。结果发现，与超声乳化白内障吸除术相比，传统ECCE以及MSICS也取得了很好的治疗效果，并且具有并发症少等优点。MSICS不需要依赖昂贵的仪器，并且具有手术快速、费用低廉以及技术门槛低等特点，特别适用于硬核白内障的治疗。虽然在白内障手术治疗过程中MSICS需要一定的技术和耐心，但它仍然是一种安全、有效、经济治疗手段，特别是在发展中国家可以替代超声乳化进行白内障的治疗。

简介：目的研究高眼压及其持续时间对大鼠视网膜caspase-3表达的影响。方法通过前房灌注平衡盐液建立大鼠急性高眼压模型：高眼压持续时间均为4h，依据眼内压的不同将sD大鼠60只随机分为正常对照组、40mmHg（1mmHg=0．133kPa）组、60mmHg组、80mmHg组、100mmHg组，每组12只。将眼内压为80mmHg的48只sD大鼠随机分为正常对照组、2h组、4h组、8h组，每组12只。正常对照组不给予前房灌注，其他各组分别给予不同的高眼压或高眼压持续不同时间。各组灌注结束后快速摘除眼球，分别采用Western印迹法和免疫组织化学法检测视网膜caspase-3的表达。结果与对照组相比，40mmHg组大鼠视网膜caspase-3的表达无增加（P〉0．05）；60mmHg组、80mmHg组和100mmHg组大鼠视网膜caspase-3的表达均强于正常对照组（q值分别为4．87、5．28和6．71；P〈0．01），但各组之间差异无统计学意义（P〉0．05）。与对照组相比，2h组大鼠视网膜caspase-3的表达差异无统计学意义（P〉0．05），4h组和8h组大鼠视网膜caspase-3的表达均增加（q值分别为2．81和3．67；P〈0．01）。表达caspase-3的视网膜细胞主要位于神经节细胞层、外丛状层和内丛状层。结论采用前房灌注平衡盐液制作急性高眼压模型研究高眼压大鼠视网膜caspase-3的表达时，眼内压为80mmHg、高眼压持续4h即可。
