光学相干断层成像对黄斑部视网膜手术疗效的评价

Evaluation of optical coherence tomography on retinal surgery of macular disease

目的 :探讨光学相干断层成像 (opticalcoherencetomography ,OCT)在黄斑部视网膜手术疗效评价中的作用。方法 :应用OCT检查 35例 35只眼行黄斑部视网膜手术的患者 ,其中特发性黄斑裂孔 2 3例 2 3只眼 ,黄斑前膜 1 2例 1 2只眼。于术前和术后 2～ 4周 ,分别对黄斑裂孔和黄斑前膜形态进行观察 ,测量裂孔直径、晕轮直径、孔缘厚度。结果 :OCT显示黄斑裂孔术后裂孔直径、晕轮直径和孔缘厚度均明显缩小。黄斑前膜术后视网膜厚度在术后 2周与术前对比 ,无显著性差异 ;术后4周与术前有显著性差异。结论 :OCT可定量客观地提供黄斑病变形态学特征 。

Objective:To evaluate the effect of optical coherence tomography(OCT)on the retinal surgery in macular disease.Methods:35 patients (35 eyes) with macular diseases (23 eyes idiopathic macular hole (IMH)and 12 eyes macular epiretinal membrane (MEM)) had been studied with OCT,and all eyes were operated on for macular disease.Preoperative and postoperative examinations included the conformation of IMH and MEM,the diameters of holes and halos,and the thickness of hole edge.Results:Postoperatively,OCT showed that the mean diameters of holes and halos ,and the thickness of hole edge became shorter obviously.The mean macular thickness before surgery was significantly different from that at 4 weeks after surgery but had no such difference from that at 2 weeks after surgery.Conclusion:OCT can objectively and quantificationally desccribe the morphological character of macular disease.The evaluation of effect on retinal surgery of macular disease is irrefragable.
