  • 简介:目的:探讨应用532倍频激光阈值下光凝治疗糖尿性黄斑水肿(diabeticedema,DME)的临床效果。方法:选取非增殖期的弥漫性DME患者32例57眼,按随机化原则分为实验组和对照组,实验组采用阈值能量的80%进行黄斑区格栅样光凝,对照组采用阈值激光进行光凝,两组除能量不同外,其他的激光治疗参数均一致。两组患者均在光凝前、光凝后1wk;1,3mo进行视力、OCT、眼底检查;在光凝前、光凝后3mo进行FFA检查;并对这些检查结果进行对比分析。结果:光凝后1mo,实验组的眼视力提高占11.1%,不变占66.7%,下降占22.2%,对照组中提高占13.3%,不变占63.3%,下降占23.3%;实验组黄斑水肿部分吸收占40.7%,不吸收占59.3%,对照组黄斑水肿完全吸收占6.7%,部分吸收占53.3%,不吸收占40.0%。实验组在视力提高和黄斑水肿吸收两方面均比对照组差,但差异没有统计学意义(P〉0.05)。光凝后3mo,实验组在视力提高和黄斑水肿吸收两方面数据接近,差异没有统计学意义(P〉0.05)。结论:阈值下激光光凝治疗DME可取得和阈值激光相似的治疗效果,并可减少激光对视网膜的损害。

  • 简介:目的:分析增殖期糖尿视网膜病变(proliferativediabeticretinopathy,PDR)患者进行围手术期干预的临床效果。方法:回顾性分析2009—05/2011—12我院40例52眼糖尿视网膜病变的病历及随访资料,其中男15例20眼,女25例32眼,年龄31~78岁。全部患者术前均进行视力、眼压、裂隙灯显微镜眼底检查、眼B超、角膜内皮镜等检查,术后1,2wk;1,2,3,6mo随访,观察患者的视力、眼压、人工晶状体、眼底情况,围手术期观察患者的血糖、血压、全身情况、不良事件等结果。全部患者实施围手术期干预措施。依据患者患有的与糖尿相关的全身合并症的诊断进行评分,每种合并症记1分,无合并症记0分。手术方式为玻璃体切割十全视网膜光凝,合并黄斑水肿及黄斑前膜者行黄斑内界膜剥离,合并白内障者同期行自内障超声乳化吸出,I期植入或不植入人工晶状体,根据术中情况眼内填充长效气体/硅油/曲安奈德;术中常规进行心电监护,出现明显血压波动者在麻醉医师监护下行控制性降压。结果:所有糖尿视网膜病变患者中I型5例,双眼手术者12例(30%),左右眼各14例(35%)。PDRIV期15眼(28.8%),V期16眼(30.8%),VI期21眼(40.4%)。术前视力低于0.02者38眼(73.1%),0.02~0.1者7眼(13.5%),0.1~0.3者5眼(9.6%),0.3以上者2眼(3.8%)。术后随访视力低于0.02者17眼(32.7%),0.02~0.1者9眼(17.3%),0.1~0.3者14眼(26.9%),0.3以上者12眼(23.1%)。1次手术治愈者47眼(90.4%),再次手术者5眼(9.6%);术后早期轻度玻璃体再出血者5眼(9.6%),晚期玻璃体再出血合并新生血管性青光眼者1眼(1.9%),感染性眼内炎者1眼(1.9%)。本组患者在我院内科确诊患有合并症的患者为17例(42.

  • 简介:眼遗传病中有些是单基因遗传,有些是多基因遗传。有些眼遗传的发病还需要特定的环境因子或表观遗传学与致病基因共同作用。致病基因和致病突变位点都存在异质性,而且不同地域或民族间有较大差异。近年来,很多与眼遗传相关的致病基因或致病突变位点被相继报道,这些已知的致病突变位点可作为基因标记,用于眼遗传的临床基因诊断、症状前诊断和产前诊断。本文主要关注常见眼遗传的基因标记,介绍眼遗传分子诊断的常用技术,并讨论如何建立较规范和完善的眼遗传分子诊断体系。
