  • 简介:目的:研究板层角膜切除术联合那霉素治疗真菌性角膜溃疡的临床疗效及组织病理学基础。方法:选取2009-12/2011-11真菌性角膜溃疡患者32例32眼,角膜病变未累及内皮层,行角膜板层切除联合那霉素滴眼治疗,观察记录治疗前后视力、角膜情况、病程、并发症及致病菌种类,对切除组织行组织病理学检查。结果:治疗前视力≤0.05者20眼,~0.3者11眼,〉0.3者1眼。板层切除术后联合那霉素治疗痊愈28例(87.5%),治愈时间7~32(平均13.2±8.5)d,痊愈时视力≤0.05者5眼,~0.3者8眼,〉0.3者15眼。病情控制不良改行角膜移植术者4例。31例真菌培养阳性(96.9%),其中镰刀菌18例,曲霉菌属8例,链格孢霉3例,未知菌属2例。病理学检查显示溃疡灶中有多量中性粒细胞浸润,过碘酸-希夫(PAS)染色显示角膜组织中菌丝多数位于角膜浅层,并呈与板层胶原纤维平行方向生长,但也有少数呈斜形或垂直生长方式,侵及切除组织全层。不同菌属之间菌丝在角膜中生长方式无明显差异。结论:对于病变未累及全层的真菌性角膜溃疡患者,及时行板层角膜切除术可大大提高那霉素药物治疗有效性,缩短病程,恢复视力。

  • 简介:目的观察白三烯拮抗孟鲁司特对儿童分泌性中耳炎(SOM)声导抗曲线恢复的作用。方法选取门诊急性SOM患儿80例(108耳),随机分为观察组和对照组,观察组42例(56耳)、对照组38例(52耳)。2组均给予抗生素1周、糠酸莫米松鼻喷雾2周及黏液促排2周治疗,观察组在此基础上加用白三烯拮抗孟鲁司特,疗程2周,观察疗效。结果观察组的有效率(69.6%)明显高于对照组(42.3%),差异有统计学意义(P〈0.05)。结论在儿童SOM的治疗中加用白三烯拮抗有助于声导抗曲线的恢复。

  • 简介:目的探讨用改良圈匙娩核并注重粘弹应用对防止小切口非超声乳化白内障囊外摘出人工晶体植入术并发症的作用。方法用改良圈匙娩核并注重粘弹应用对355例白内障行小切口非超声乳化白内障人工晶体植入术。结果术后三天矫正视力≥0.5者291眼达82%,脱残339眼(95.5%)脱盲315眼(98.9%)。术后角膜水肿39眼,占10.98%均在3~6天后恢复透明。后囊破裂7眼,占1.97%,前房出血4眼,占1.13%。瞳孔轻度变形10眼,占2.8%,暂时性高眼压4眼,占1.13%。结论在行小切口白内障囊外摘出人工晶体植入时,应用改良后的圈匙娩核并注重粘弹应用,就会明显减少并发症,达到良好的效果。
