  • 简介:目的探讨玻璃体的手术对复杂无晶状体眼视网膜脱离(AphakicRetinalDetachment,ARD)和人工晶状体眼视网膜脱离(PseudophakicRetinalDetachment,PPRD)(PVRC以上)的治疗效果.方法回顾性分析78例87眼ARD和PPRD,所有病人均行玻璃体切割联合眼内填充物治疗.结果首次手术视网膜复位率为78.16%,最终视网膜复位率90.8%.视力下降11眼(12.7%),不变15眼(17.2%),提高59眼(70.1%).结论彻底的玻璃体切除加视网膜切开、视网膜前膜剥除,适当应用环扎玻璃体填充物可使复杂PPRD,ARD达到较高的视网膜复位率.但ARD、PPRD旦发生则病情进展迅速,治疗棘手,视力预后差,应从白内障手术开始加强预防.

  • 简介:目的:观察4种睑下垂术式的临床效果。方法:为探讨睑下垂术的有效治疗方法,不断改进手术方式。结果:每种手术均有其优点及并发症,提上睑肌折叠术为目前较为理想的手术方法。结论:临床实践提上睑肌折叠术与以往专家理论:提上睑肌节制韧带上每缩短3~5mm肌肤,可矫正下垂量1mm不同:在节制韧带上缘折叠提上睑肌腱膜即可提起睑,且睑缘正好在角膜缘2mm,术后恢复在角膜缘处。

  • 简介:质量是个难以描述及定义的概念。人们对质量的评定各有不同的见解。拿出租车旅行来打个比方。你如何评定旅行的质量?你的评定时基于司机是否有礼貌还是车子的豪华程度?或者以你安全到达目的地为标准?如果让你的司机来评价同样场旅行的质量,他们可能认为旅途中没有抛锚或没有被交通事故耽搁就是好。评定质量有很多不同的标准,以那点为准取决于你的角色。
