简介:目的:分析复方血塞通联合康柏西普对病理性近视脉络膜新生血管(choroidalneovascularization,CNV)患者黄斑中心视网膜厚度(centralmacularretinalthickness,CMT)、荧光素眼底血管造影及最佳矫正视力(BCVA)的影响。方法:根据不同治疗方法将60例60眼病理性CNV患者分为观察组(复方血塞通联合康柏西普治疗)与对照组(单纯康柏西普治疗),各30例,比较两组患者治疗前后CMT、眼压(IOP)、CNV面积、BCVA及血清中血管内皮生长因子(VEGF)变化情况,统计随访期间并发症情况。结果:观察组术后12wk视力恢复总有效率(97%)显著高于对照组的80%,差异有统计学意义(P〈0.05);与术前比较,两组患者术后12wk时CMT、IOP、CNV面积及血清VEGF水平均显著下降,BCVA显著提高,差异有统计学意义(P〈0.01),且观察组术后上述指标均明显优于对照组,差异有统计学意义(P〈0.01)。两组患者均无局部并发症及全身严重并发症发生。结论:复方血塞通联合康柏西普能有效降低CMT及IOP,缩小CNV面积,显著提高视力。

简介:目的分析角膜塑形镜试戴患者的基本情况及相关屈光参数,以期提高试戴成功率,并分析试戴失败原因。方法回顾分析45例(89只眼)进行角膜塑形镜试戴近视眼患者的资料。结果45例患者中,41例(91.1%)试戴成功,其中37例(82.2%)定制了镜片;4例(8.9%)试戴失败。通过对达到良好适配时的K值与平坦K值比较,得出角膜越平坦,两者的差值越小;而角膜越陡峭,两者的差值越大。4例试戴失败病例中,3例E值较试戴成功者E值明显偏低(P〈0.01),1例存在逆规散光。结论严格掌握好角膜塑形镜试戴者人选标准、规范验配流程,才能提高角膜塑形镜试戴成功率。对于E值偏低及存在逆规散光的患者试戴须谨慎。(中国眼耳鼻喉科杂志,2010,10:221.223)
