简介：目的探讨康柏西普联合激光光凝治疗视网膜分支静脉阻塞继发黄斑水肿的效果。方法选择本院2016年1月至2017年6月收治的90例（98眼）视网膜分支静脉阻塞继发黄斑水肿患者,根据随机数字表法将其分为两组,各45例（49眼）。对照组采用激光光凝治疗,观察组采用康柏西普联合激光光凝治疗,比较两组最佳矫正视力、黄斑中心视网膜厚度。结果观察组治疗1周后、治疗3个月后BCVA水平较对照组高,CMI水平均较对照组低,差异具有统计学意义（P〈0.05）。结论康柏西普联合激光光凝治疗视网膜分支静脉阻塞继发黄斑水肿效果确切,可明显改善黄斑中心视网膜厚度,促进患者视力恢复。

简介：目的：研究家兔静脉注射头孢哌酮钠／舒巴坦钠在眼内的透过性及蓄积作用。方法：用高效液相色谱法（highperformanceliquidchromatography，HPLC）测定给药后不同疗程时间点各组兔眼房水和玻璃体中的药物浓度。结果：房水中舒巴坦钠的药物浓度分别为23．4±4．8和23．6±3．7mg／L；头孢哌酮钠浓度分别为8．9±1．2和8．9±1．7mg／L；玻璃体中舒巴坦钠浓度分别为71．2±4．6和69．3±6．8mg／L，头孢哌酮钠未检出。结论：头孢哌酮Ca／舒巴坦钠静脉注射后在正常的眼内透过性不良。
