Abstract： 目的了解光相干断层扫描(optical coherence tomography, OCT)对检测巩膜扣带术后黄斑形态改变及与视功能的意义. 方法应用Zeiss-Humphrey OCT检查仪对68例(70只眼)巩膜扣带术复位成功的患者黄斑区进行经中心凹水平、垂直扫描,观察黄斑形态. 结果 70只受检眼中,黄斑区结构正常22只眼,神经上皮平均厚度为(146.47±20.59) μm,黄斑结构异常48只眼,检测异常率为68.6%,其中黄斑区视网膜神经上皮下较多残液"间隙"存留19只眼,局限性残液存留9只眼;黄斑区视网膜水肿8只眼,神经上皮变薄4只眼,黄斑区、后极部视网膜下增生4只眼,黄斑、后极部视网膜前膜4只眼.OCT黄斑结构正常组,手术后2周视力≥0.3者:6只眼,3个月时有14只眼;黄斑水肿组8只眼,手术后2周视力≥0.3者:1只眼,3个月时有2只眼;视网膜神经上皮下残存液体,手术后2周视力≥0.3者5只眼,3个月时有23只眼,说明巩膜扣带术后的黄斑结构变化与手术后视功能存在一定关系.随访3个月时,黄斑正常组、神经上皮脱离组和其它病变组视力在0.3以上所占的比例差异有显著性的意义(χ2=18.91,P＜0.01). 结论 OCT能精确地探查视网膜复位术后黄斑结构的变化,并且能较好地解释患眼视功能变化.
