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。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 （P0.05）.The posteriorpole average thickness of RD subjects was 175.50±33.85μm with no significant difference compared with the fellow eyes （P0.05）.The posteriorpole maximum thickness of RD subjects was 310.18±158.40μm with significant difference compared with the fellow eyes （P0.01）. 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.
