简介:泪道阻塞是眼科的常见病,有先天性和后天性两大类,易发展为急,慢性泪囊炎,以手术治疗为主,目的是重建或恢复泪液的引流通路,传统手术方面报道较多的是泪囊鼻腔吻合术(EXT-DCR)虽然成功率可达85%,但在颜面部残留永久性疤痕,影响美容,非手术方法主要有:探通,置线,置管等,但只是简单的解决问题,而且易致周围组织刺激,更容易形成粘连和疤痕使管腔再度阻塞。目前,虽然报道使用激光泪道成形术收到较好的效果,泪道能够冲洗通畅,但部分仍有溢泪症状。近年来,随着内窥镜技术不断成熟,既微创又美观的手术要求越来越高,因此,诸如鼻内窥镜下泪囊鼻腔吻合术(IECR)得以开展和创新。另外高分子材料及其它医疗器械的不断更新和完善,其治疗手段有了长足的进步。
简介:目的探讨带虹膜隔张力环植入手术治疗虹膜缺损的护理措施。方法回顾分析我院所诊治的虹膜缺损患者24例,24例患者均行带虹膜隔张力环植入的手术,针对性的对该手术不同类型的患者加强心理护理、术前准备、术后护理及预防并发症的发生。结果所有患者均根据虹膜缺损的范围和程度选择并放置合适型号的带虹膜隔张力环,术后随访3个月,均未发现张力环、人工晶状体偏位、移位,晶状体囊袋损伤及瞳孔阻滞等现象。结论囊袋内植入带人工虹膜的张力环治疗部分或完全虹膜缺损,取得了较好的治疗效果,开辟了该类疾病治疗的新思路,手术期间应加强患者的心理护理及术后的密切观察,及时采取相应的护理措施,从而减少并发症,提高疗效。
简介:亚洲神经眼科协会(ASNOS)于2002年在日本东京成立。由亚洲神经眼科协会每两年主办一次的亚洲神经眼科大会是一个大型国际神经眼科会议,代表了亚洲神经眼科基础研究及临床研究的最高水平。历届会议都有数百名各国神经眼科专业人士进行学术交流,对国际最近神经眼科新技术及学术前沿进行介绍及讨论。亚洲神经眼科大会提供了一个国际化平台,让世界各地的参会者对前沿的神经眼科研究课题交流想法,探讨最新进展及促进未来的合作。在亚洲神经眼科大会中一个尤其出名且重要的病例讨论版块“WalshinAsia”,选取各国出色的带病理结果的病例进行深入剖析,非常具有挑战性。
简介:目的探讨不同手术方式治疗复发性翼状胬肉的疗效。方法选取复发性翼状胬肉患者60例(60只眼)随机分成两组:A组30个病人(30只眼)翼状胬肉切除联合冻干羊膜移植术;B组30个病人(30只眼)翼状胬肉切除联合带自体角膜缘干细胞结膜瓣移植术。结果两组病人术后随访6个月至2年,翼状胬肉切除联合冻干羊膜移植术组与翼状胬肉切除联合带自体角膜缘干细胞结膜瓣移植术组术后复发率分别为:36.7%和10%,差异具有统计学意义(P〈0.05).结论复发性翼状胬肉的治疗中翼状胬肉切除联合带自体角膜缘干细胞结膜瓣移植术相对于翼状胬肉切除联合冻干羊膜移植术疗效更明确。

简介:目的观察自制全结膜囊羊膜固定器在重症眼表烧伤行羊膜遮盖手术中应用效果。方法在11例(13眼)眼部重症烫伤患者治疗中采用自制全结膜囊羊膜固定器将羊膜固定于眼表及眼睑皮肤面。根据病情需要更换羊膜,随访3月至3年。结果患者平均手术时间为(8.0±3.0)分钟;眼表组织上皮化时间(13.2±11.3)天。重复手术次数3.5次,患者手术依从性良好,观察病例无角膜穿孔,无睑球粘连。结膜囊狭窄5例,角膜斑翳5例,角膜血管化2例。结论采用自制全结膜囊羊膜固定器手术,缩短手术时间,无创伤,重症烧伤患者可多次重复手术,特别适合重症眼表烧伤早期治疗,减少晚期严重并发症的发生。
简介:目的:探讨高度近视黄斑病变的光学相干断层扫描(OCT)和眼底荧光血管造影(FFA)的形态学特征、分类和对比分析。方法:对入选的高度近视黄斑病变患者61例101眼均行标准对数视力表检查,验光确定屈光度及最佳矫正视力(BCVA),并用IOL-Master测量眼轴长度。入选者需在同一天内行散瞳眼底检查、OCT及FFA检查,必要时行眼底联合造影(FFA&ICGA)。分析不同类型的OCT及FFA形态学特征之间的相互联系,并探讨其与屈光度、最佳矫正视力、眼轴长度及中心凹厚度之间的关系。结果:FFA分类的漆样裂纹型在OCT分类的1型中所占比例为57.14%,显著高于新生血管型和黄斑萎缩型(21.43%),差异有统计学意义(P<0.05)。FFA分类的黄斑萎缩型在OCT分类的2型中所占的比例为67.80%,显著高于漆样裂纹型(18.64%)和新生血管型(13.56%),差异有统计学意义(P<0.05)。OCT3型均属于FFA分类的黄斑萎缩型。OCT1型的屈光度、眼轴长度明显低于2型和3型,而最佳矫正视力和中心凹厚度则明显高于2型和3型。FFA的漆样裂纹型与新生血管型在屈光度及眼轴长度上虽无明显差异,但后者的BCVA及中心凹厚度显著低于前者(P<0.05)。漆样裂纹型及新生血管型的屈光度、眼轴长度均显著低于黄斑萎缩型,最佳矫正视力则明显高于黄斑萎缩型(P<0.05)。结论:高度近视黄斑病变的OCT和FFA形态学特征密切相关,结合OCT和FFA的图像特征对高度近视黄斑病变形态学改变进行对比分析,不仅有助于明确病变的性质,提高我们对疾病发病机制及预后转归的认识,更为临床诊疗提供了有力的支持。
