摘要
目的 探讨光学相干断层扫描 (optical coherence tomography,OCT)图像在评价特发性黄斑裂孔 (idiopathic macular hole,IMH)手术疗效中的作用。 方法 用 OCT检测 19例 IMH患者 19只眼手术前、后的裂孔直径、孔晕直径、孔缘厚度及裂孔形态变化特征。 结果 OCT定量检测显示 ,裂孔直径平均由术前 (5 70 .95± 2 6 4.5 9)μm减少到术后 (337.0 5± 335 .95 )μm,孔晕直径平均由术前 (10 43.5 3± 2 78.80 )μm减少到术后 (6 95 .0 0± 483.0 0 )μm,孔缘厚度平均由术前 (389.78± 6 0 .5 8)μm减少到术后 (2 98.78±10 9.80 )μm。裂孔闭合、缩小 ,孔晕缩小 ,孔缘厚度减少共 17只眼 ,手术解剖成功率为 89%。 结论 OCT能客观、精确、有效地判断 IMH手术的解剖疗效。
Purpose To evaluate the surgical effect of idiopathic macular hole (IMH),with optical coherence tomography (OCT). Methods To measure the diameter of holes and hole halos,the thickness of hole in edge,the changes of hole pattern in 19 cases (19 eyes) with IMH using OCT. Results By quantitatively measuring,OCT showed that after surgery the mean hole diameter lessened from (570.95±264.59) μm to (337.05±335.95) μm.The mean diameter of hole halo lessened from (1 043.53±278.80) μm to (695.00±483.00) μm and the mean thickness of the hole edge thinned from (389.78±60.58) μm to (298.78±109.80) μm.In 17 eyes the holes became closed or reduced in size or the hole halo,and thinned in hole edge.The anatomic successful rate of the surgery is 89%. Conclusion OCT can objectively,accurately and effectively judge the anatomic effect of IMH surgery.
