视网膜脱离巩膜扣带术后后极部视网膜定量分析

Measurement of human retinal thickness at posterior pole after successful scleral buckling surgery using retinal thickness analyzer

摘要:

目的:研究视网膜脱离(retinal detachment,RD)巩膜扣带术后后极部视网膜水肿情况。方法:应用视网膜厚度分析仪(RTA)对38例38眼孔源性RD巩膜扣带术后手术成功眼后极部视网膜厚度进行测量。结果:术后进行RTA测量随访的时间为72.61±57.27d,经RTA测量,RD术后黄斑中心凹平均厚度168.03±38.27μm,与对侧眼比较二者差异无显著性(P>0.05);RD眼术后后极部平均厚度175.50±33.85μm,与对侧眼比较二者差异无显著性(P>0.05),RD眼术后后极部最大厚度(310.18±158.40μm)与对侧眼比较,二者差异有显著性(P<0.01)。结论:通过RTA可精确测量并观察后极部视网膜水肿发生情况,视网膜脱离巩膜扣带术后2mo后极部视网膜局限性水肿仍存在,术后这个时间患者仍存在视物变形与此有关,仍需进行进一步的长期随访观察后极部视网膜水肿消退的时间。而且,在这段时间内考虑给予相应的干预治疗,以改善视功能。

Abstract:

AIM:To investigate retinal edema at posterior pole after scleral buckling surgery for retinal detachment (RD). METHODS:Retinal thickness analyzer(RTA) was used to measure the retinal thickness at the posterior pole in 38 eyes of 38 patients after scleral buckling surgery for RD. RESULTS:Average follow-up time was 72.61±57.27 days after scleral buckling surgery.The foveal average thickness of RD subjects was 168.03±38.27μm with no significant difference compared with the fellow eyes (P>0.05).The posteriorpole average thickness of RD subjects was 175.50±33.85μm with no significant difference compared with the fellow eyes (P>0.05).The posteriorpole maximum thickness of RD subjects was 310.18±158.40μm with significant difference compared with the fellow eyes (P<0.01). CONCLUSION:Through the RTA the occurrence of retinal edema of the posterior pole can be accurately measured and observed, posterior pole retinal localized edema persists 2 months after scleral buckling for retinal detachment. The metamorphopsia of patients are related with it during this period of time after surgery. It still needs a very long-term follow-up to observe withdrawal time of retinal edema. Moreover, in this period of time, it is considered for the appropriate intervention to improve visual function.
