  • 简介:目的:评价青光眼患者的生存质量并探讨影响其生存质量的因素。方法:采用国家眼科研究所视功能问卷-25,对126例青光眼患者的生活质量进行评价。结果:青光眼患者的生存质量普遍下降,不同程度的视力损害明显影响着患者的生存质量得分(P〈0.01)。多因素逐步直线回归显示:生存质量的得分与年龄、经济收入、遵医行为有密切关系(P〈0.05)。结论:在保护青光眼患者视功能的同时,要重视其社会、心理等因素,给予其必要的健康教育和心理辅导,以期提高其生存质量。

  • 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。
