  • 简介:目的探讨白内障超声乳化联合人工晶状体植入治疗原发性闭角型青光眼伴白内障的疗效。方法选取2015年2月至2016年10月在我院治疗的原发性闭角型青光眼伴白内障患者82例103眼,均给予白内障超声乳化联合人工晶状体植入治疗,观察治疗前后视力、眼压、中央前房深度(ACD)、房角开放距离500(AOD500)、房角开放情况以及并发症。结果术后3个月、6个月、12个月最佳矫正视力明显较术前改善(P〈0.05);患者术后3个月、6个月和12个月眼压明显较术前降低(P〈0.05);术后6个月和12个月眼压分别为(15.43±1.55)mmHg和(15.50±1.60)mmHg,高于术后3个月眼压(P〈0.05),但明显低于术前(P〈0.05);患者术后3个月、6个月和12个月ACD和AOD500明显较术前改善(P〈0.05);术后3个月、6个月和12个月房角关闭情况明显较术前改善(P〈0.05),其中术后12个月房角开放眼数达28眼,占27.18%;术后未出现人工晶体夹持、黄斑囊样水肿、角膜失代偿等并发症。结论白内障超声乳化联合人工晶状体植入治疗原发性闭角型青光眼伴白内障有较好的效果,能改善患者视力、降低眼压、开放房角。

  • 简介:目的:利用频域三维相干光学断层扫描(threedimensionalfrequencydomaincoherentopticaltomography,3D-OCT)评估准分子激光原位角膜磨镶(laserinsitukeratomileusis,LASIK)对视网膜神经纤维层厚度(retinalnervefibrelayerthickness,RNFLT)的影响。方法:对83例83右眼接受LASIK治疗的受试者分别于术前及术后1d;1wk;1,3mo行3D-OCT检查,测量视乳头上方、下方、鼻侧、颞侧及12个钟点位RNFLT,利用重复测量方差分析及配对t检验对术前及术后的数据统计学处理。结果:术前及术后各时间点行重复测量方差分析显示,视乳头下方、颞侧、5:00~11:00位RNFLT均值无显著差异(P〉0.05),而视乳头上方、鼻侧、1:00~4:00位、12:00位RNFLT有显著差异(P〈0.05);进一步对术前及术后各时间点视乳头上方、鼻侧、1:00~4:00位、12:00位RNFLT分别行配对t检验得出,术后1d时视乳头上方、鼻侧及1:00~4:00位、12:00位RNFLT较术前变薄,差异有统计学意义(P〈0.05),术后1wk;1,3mo时以上各方位RNFLT较术前比较均无统计学差异(P〉0.05)。同时表明RNFLT变薄与屈光度及激光时间成正相关。结论:LASIK术后早期上方及鼻侧RNFLT变薄,但术后1wk恢复至正常水平,LASIK手术对RNFLT无长远影响。
