简介：目的采用不同色彩多焦视网膜电图（mfERG）刺激模式刺激正常眼黄斑部视网膜,观察不同刺激模式mfERG的波形改变及其特征,为将不同色彩刺激模式mfERG应用于黄斑疾病的检测提供正常基线标准和评估检查的可行性。方法分别采用黑/白刺激模式、黑/红刺激模式和黑/绿刺激模式对19例正常视力成年志愿者进行检测,比较分析一阶kernel反应（FOK）的平均反应密度和峰时变化特征,以及稳态闪烁光反应（flicker-30Hz）的平均反应密度和峰时的变化特征。结果正常人FOK以及flicker-30Hz1~5环P1波潜时与刺激色彩的亮度呈负相关,而P1波平均反应密度与刺激色彩亮度呈正相关,P1波峰时和平均反应密度与平均亮度均呈线性回归关系,表现为其亮度特征。结论不同色彩刺激模式存在亮度效应,由不同色彩的不同亮度特征性改变可以客观反映黄斑区不同亮度通道的功能情况。

简介：目的：探讨扭动模式超声乳化对年龄相关性白内障患者眼角膜的影响。方法：选取我院2012-01/2014-12眼科住院的年龄相关性白内障患者161例196眼,按随机化原则分为扭动模式组（A组）和传统模式组（B组）,晶状体核硬度按照Emery标准进行分级。记录术中所使用的有效超声时间（ultrasoundtime,UST）、有效累积释放能量（cumulativedissipatedenergy,CDE）,并比较术后最佳矫正视力（bestcorrectedvisualacuity,BCVA）、眼角膜水肿程度（cornealedemadegree,CED）、眼角膜中央厚度（centralcornealthickness,CCT）和眼角膜内皮细胞丢失率。结果：两组患者各级核硬度手术中所使用的UST和CDE比较,A组较B组低。术后的平均最佳矫正视力比较,术后1、7d时A组较B组高,而术后30d两组差异无统计学意义（P〉0.05）。眼角膜水肿和CCT比较,术后1、7d时A组较B组眼角膜水肿轻,平均CCT厚,术后30d两组患者差异无统计学意义（P〉0.05）。术后7、30d平均眼角膜内皮细胞计数比较,A组较B组高,丢失率低。结论：由于缩短了术中UST和减少了CDE,扭动模式超声乳化减轻了对眼角膜内皮细胞的损伤,使得患者术后恢复周期缩短,但并未根本解决超声乳化对眼角膜造成的损伤。
