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:目的对临床可疑青光眼患者进行长期的偏振激光扫描仪联合个体化角膜补偿技术(scanninglaserpolarimetrywithvariablecornealcompensation,GDxVCC)随访,分析GDxVCC对该类患者的诊断价值。方法选取门诊可疑青光眼的眼底检查视乳头杯/盘比(C/D)≥0.4,或双眼不对称且C/D差值〉10.2,静态视野检查结果正常患者68例,随访前后均用GDxVCC检查(采用相同的角膜补偿值)。如双跟C/D值相同,随机选取1眼,如C/D值不同,则选取C/D值大的1眼,对结果进行t检验统计学分析。结果随访时间6~30个月,平均(12.5±7.0)个月,眼底C/D值为0.57±0.17。随访前后GDxVCC检查:椭圆平均值分别为50.33±7.72和49.66±8.12,上方平均值为58.72±13.56和58.18±12.01,下方平均值为60.71±11.31和59.13±11.95,神经纤维指数为30.85±19.62和33.03±21.22,差异无统计学意义,但从绝对数值上,椭圆平均值、上方平均值和下方平均值变小,神经纤维指数变大。其中7例(10.3%)诊断为青光眼,21例(30.9%)排除青光眼,40例(58.8%)仍需进一步随访。结论对临床怀疑青光眼的患者应长期进行随访,GDxVCC随访对青光眼的诊断有一定的价值。(中国眼耳鼻喉科杂志,2009,9:92—94)
简介:目的观察准分子激光原位角膜磨镶术(laserinsitukeratomileusis,LASIK)后早期眩光对暗视下对比敏感度的影响。方法采用MesotestⅡb对比敏感度仪,检测72例行LASIK患者术后3个月的对比敏感度,并比较有和无眩光两种情况对暗视下对比敏感度的影响。结果无眩光时,未通过各测试等级的患者数较术前增加,但仅第4级(1:2)差异有统计学意义;有眩光时,各测试等级未通过患者数较术前明显增加,第6级(1:5)、第7级(1:2.7)、第8级(1:2)差异均有统计学意义。暗视下有眩光时,对比度降低2个等级以上的患者数明显多于无眩光时,差异有统计学意义。结论LASIK术后早期有眩光时暗视下对比敏感度明显降低。
简介:目的:探讨激光周边虹膜成形术(laserperipheraliridoplasty,LPIP)治疗急性闭角型青光眼(acuteangle-closureglaucoma,AACG)急性发作期药物不能控制的高眼压持续状态中的疗效。方法:原发性急性闭角型青光眼67例69眼发作期药物治疗3~6h后眼压仍〉30mmHg时,行LPIP治疗。监测术前和术后30,60min和2h眼压、视力变化。应用UBM测量术前、术后2h房角宽度和虹膜厚度,并应用房角镜观察前房角粘连情况。结果:LPIP后2h,房角开放距离(AOD)较术前明显增大(P〈0.01),小梁虹膜夹角(TIA)增宽、部分患者周边虹膜前粘连(PAS)减少、周边虹膜变薄。所有患者眼压在激光虹膜成形术后不同时间均有不同程度下降。术前平均眼压53.81±10.22mmHg,术后30min平均眼压33.81±9.22mmHg,术后60min为21.93±7.19mmHg,2h后眼压下降至15.16±3.07mmHg,治疗前后差异有显著统计学意义(F=151.79,P〈0.01)。同时所有患者视力都有所提高。结论:LPIP可以明显加深患者的周边前房,增宽房角入口,降低患者眼压,是治疗AACG急性发作期药物不能控制高眼压持续状态的重要辅助措施,为青光眼的进一步治疗创造了条件,并且能够改善预后。
