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:比较病理性高度近视黄斑裂孔性视网膜脱离(MHRD)手术中硅油与C3F8填充后视网膜复位率和高眼压发生率,为此类手术的填充物提供临床参考。方法:采用回顾性病例对照设计。在不同时间段连续观察病理性高度近视MHRD患者,分别采用玻璃体切割联合眼内填充硅油和气体的两组患者分别进行观察,从手术后1wk;1,3,6,12mo,视网膜复位率和眼压进行对比研究,观察患者视网膜复位及眼压的情况,得出最佳的填充方式。结果:初次手术后,硅油组视网膜复位率高于气体组,但两组视网膜复位率差异无统计学意义;患者眼压:硅油组高眼压发生率高于气体组,但差异无统计学意义。结论:病理性高度近视MHRD患者玻璃体手术后使用哪种填充物,应采取个体化方案。
