摘要
目的 应用光学相干断层成像术 (opticalcoherencetomography ,OCT)研究巩膜扣带术后非屈光性视物变形患者的黄斑复位情况 ,探讨视物变形的原因和预后。方法 选择 82例 ( 82眼 )原发性裂孔性视网膜脱离患者 ,均经巩膜扣带术获得视网膜解剖复位但主诉视物变形 ,验光后无法矫正 ,利用OCT对黄斑区进行经中心凹水平和垂直线形扫描。结果 OCT检查患眼黄斑区有神经上皮下积液、神经上皮水肿、神经上皮变薄、黄斑前膜、黄斑下膜和黄斑区视网膜下出血 6种异常表现。其中 ,神经上皮下积液共 67眼 ( 82 % ) ,脱离高度平均为 ( 12 1± 10 1 3 6) μm ,脱离范围从 2 46μm到整个扫描区神经上皮下积液 ;神经上皮水肿共 11眼 ,中心凹处神经上皮厚度平均为 ( 3 64± 5 8) μm ;神经上皮变薄共 9眼 ,中心凹处神经上皮厚度平均 ( 92± 13 84) μm。 结论 OCT不仅能够精确的检测巩膜扣带术后黄斑复位情况 ,解释非屈光性视物变形的原因 ,而且能够对术后黄斑进行定量测定和随访 。
Objective Applying optical coherence tomography(OCT) to study the condition of macular reattachment for those who had non refractive visual distortion after scleral buckling surgery and detect the causes and prognosis of visual distortion.Methods To select 82 patients(82 eyes)who suffered from primary rhegmatogenous retinal detachment and successfully reattached by scleral buckling surgery but complied visual distortion which could not be corrected.To scan the macula of these patients through the fovea vertically and horizontally with OCT.Results Six abnormal conditions of macular reattachment were observed,including subretinal fluid,retinal edema,retina thinning,preretinal membrane,subretinal membrane and subretinal blood.Subretinal fluid occurred in 67 eyes(82%).The detachment height meant(121±101 36)μm and ranged from 246μm to all scanning area.Retinal edema occurred in 11 eyes and its thickness meant(364±58)μm.Retina thinning occurred in 9 eyes and its thickness meant(92±13 84)μm.Conclusions OCT can not only observe the condition of macular reattachment after scleral buckling surgery and explained the causes of non refractive visual distortion,but also measure the maculopathy in quantity,which was important in the follow up and prognosis.
